Engineering Selection Recommendations
Direct Equivalent (Same Manufacturer)
AD8052ARMZ is the recommended direct equivalent to the obsolete AD8052ARM. Both devices are manufactured by Analog Devices Inc. and share identical electrical specifications across all critical parameters: 170 V/µs slew rate, 80 MHz gain bandwidth product, 110 MHz -3dB bandwidth, 1.4 µA input bias current, and 1.7 mV input offset voltage. The AD8052ARMZ is classified as Active product status and is ROHS3 compliant, providing long-term supply chain continuity. The primary difference is packaging format: AD8052ARMZ is supplied in Tube packaging, whereas the original AD8052ARM packaging format is not specified. Both devices operate across the identical -40°C to 125°C temperature range and 3V to 12V supply span.
Texas Instruments LMH6643 Series
The LMH6643MM/NOPB, LMH6643QMM/NOPB, and LMH6643QMMX/NOPB devices from Texas Instruments are functionally equivalent voltage feedback amplifiers with dual-channel, rail-to-rail output configuration. These devices feature a -3dB bandwidth of 130 MHz, exceeding the AD8052ARM specification of 110 MHz. The slew rate of 135 V/µs is lower than the AD8052ARM (170 V/µs) but remains within acceptable substitution parameters. Input bias current is 1.6 µA and input offset voltage is 1 mV, both meeting or exceeding the AD8052ARM specifications. Supply current is reduced to 2.7 mA (x2 Channels) compared to 4.8 mA, and output current per channel is increased to 75 mA versus 45 mA. All three variants are ROHS3 compliant and MSL 1 rated. The LMH6643QMM/NOPB and LMH6643QMMX/NOPB variants include AEC-Q100 automotive qualification. Operating temperature range is -40°C to 85°C, which is narrower than the AD8052ARM (-40°C to 125°C). Maximum supply voltage is 12.8V for the LMH6643MM/NOPB and 10V for the automotive-qualified variants.
Maxim Integrated Buffer Amplifiers
The MAX4017EUA+, MAX4017EUA+T, MAX4217EUA+, and MAX4217EUA+T devices are buffer-type voltage feedback amplifiers with enhanced slew rate (600 V/µs) and bandwidth performance. The MAX4017 series provides 200 MHz -3dB bandwidth, while the MAX4217 series provides 230 MHz -3dB bandwidth. These devices feature higher input bias current (5.4 µA) and input offset voltage (4 mV) compared to the AD8052ARM, and higher supply current (5.5 mA x2 Channels). Output current per channel is significantly higher at 120 mA. Supply voltage range is 3.15V to 11V. Operating temperature range is -40°C to 85°C. All variants are ROHS3 compliant and MSL 1 rated. The primary distinction between variants is packaging: EUA+ denotes Tube packaging, while EUA+T denotes Tape & Reel packaging.
Maxim Integrated Video Amplifier
The MAX4392EUA+ is a video amplifier with voltage feedback topology, dual-channel configuration, and rail-to-rail output. This device features 500 V/µs slew rate and 85 MHz -3dB bandwidth. Supply voltage range is 4.5V to 11V (single supply) or ±2.25V to ±5.5V (dual supply). Output current per channel is 95 mA. This device is ROHS3 compliant and MSL 1 rated. The MAX4392EUA+ is optimized for video signal processing applications and may not be suitable for general-purpose amplifier applications requiring the full bandwidth and slew rate of the AD8052ARM.
Product Status and Compliance Considerations
All substitute parts listed are classified as Active product status, ensuring ongoing availability and manufacturer support. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The AD8052ARMZ provides the most direct substitution path with identical electrical performance and Active status from the original manufacturer. Texas Instruments LMH6643 variants provide enhanced bandwidth performance with reduced power consumption. Maxim Integrated devices provide enhanced slew rate and bandwidth for applications requiring higher-speed signal processing.
Frequently Asked Questions (FAQ)
Q: Can the AD8052ARMZ be used as a direct replacement for the AD8052ARM?
A: Yes. The AD8052ARMZ is electrically identical to the AD8052ARM across all specified parameters: 170 V/µs slew rate, 80 MHz gain bandwidth product, 110 MHz -3dB bandwidth, 1.4 µA input bias current, 1.7 mV input offset voltage, 4.8 mA supply current (x2 Channels), 45 mA output current per channel, and -40°C to 125°C operating temperature range. Both devices operate across 3V to 12V supply span. The AD8052ARMZ is Active product status and ROHS3 compliant. The primary difference is packaging format (Tube for AD8052ARMZ).
Q: What are the key differences between the AD8052ARM and the Texas Instruments LMH6643 series?
A: The LMH6643 series provides higher -3dB bandwidth (130 MHz versus 110 MHz) and lower supply current (2.7 mA x2 Channels versus 4.8 mA). However, slew rate is reduced to 135 V/µs compared to 170 V/µs. Input bias current is slightly higher at 1.6 µA versus 1.4 µA, and input offset voltage is lower at 1 mV versus 1.7 mV. Output current per channel is increased to 75 mA versus 45 mA. Operating temperature range is narrower at -40°C to 85°C versus -40°C to 125°C. All LMH6643 variants are ROHS3 compliant and MSL 1 rated.
Q: Are the Maxim Integrated MAX4017 and MAX4217 devices suitable substitutes for the AD8052ARM?
A: The MAX4017 and MAX4217 devices are functionally compatible as voltage feedback amplifiers with dual-channel, rail-to-rail output configuration and identical 8-pin package footprint. However, these devices feature significantly higher slew rate (600 V/µs) and bandwidth performance (200 MHz and 230 MHz respectively), which may introduce different circuit behavior in applications sensitive to these parameters. Input bias current is higher at 5.4 µA, and input offset voltage is higher at 4 mV. Supply current is higher at 5.5 mA (x2 Channels). These devices are optimized for high-speed buffer applications rather than general-purpose amplification. Operating temperature range is -40°C to 85°C.
Q: What is the operating temperature range limitation for substitute parts?
A: The AD8052ARM operates across -40°C to 125°C. The AD8052ARMZ maintains this full temperature range. The Texas Instruments LMH6643 series and Maxim Integrated MAX4017, MAX4217, and MAX4392 devices operate across -40°C to 85°C, which is narrower than the original device. Applications requiring operation above 85°C must use the AD8052ARMZ or verify that the narrower temperature range is acceptable for the specific application.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed (AD8052ARMZ, LMH6643MM/NOPB, LMH6643QMM/NOPB, LMH6643QMMX/NOPB, MAX4017EUA+, MAX4017EUA+T, MAX4217EUA+, MAX4217EUA+T, and MAX4392EUA+) are ROHS3 compliant and REACH unaffected. The original AD8052ARM does not specify RoHS status.
Q: What is the difference between the LMH6643QMM/NOPB and LMH6643QMMX/NOPB variants?
A: Both devices are electrically identical and feature AEC-Q100 automotive qualification. The primary difference is packaging format: LMH6643QMM/NOPB is supplied in standard packaging format, while LMH6643QMMX/NOPB is supplied in Tape & Reel (TR) format. Both devices operate across -40°C to 85°C with maximum supply voltage of 10V.
Q: Can the MAX4392EUA+ be used in place of the AD8052ARM?
A: The MAX4392EUA+ is a video amplifier with voltage feedback topology, dual-channel configuration, and rail-to-rail output, making it mechanically compatible with the AD8052ARM package footprint. However, the MAX4392EUA+ features lower -3dB bandwidth (85 MHz versus 110 MHz) and is optimized for video signal processing applications. This device is suitable only for applications where the reduced bandwidth and video-specific optimization are acceptable.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in multiple packaging formats: Tube (standard packaging), Tape & Reel (TR) for automated assembly, and Cut Tape (CT) & Digi-Reel® for component distribution. The AD8052ARMZ is supplied in Tube format. The LMH6643MM/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format. The LMH6643QMM/NOPB packaging format is not specified. The LMH6643QMMX/NOPB is supplied in Tape & Reel (TR) format. The MAX4017EUA+ and MAX4217EUA+ are supplied in Tube format. The MAX4017EUA+T and MAX4217EUA+T are supplied in Tape & Reel (TR) format. The MAX4392EUA+ is supplied in Tube format. All devices use identical 8-pin surface mount package footprint (8-TSSOP, 8-MSOP).
Q: What is the Moisture Sensitivity Level (MSL) for all substitute parts?
A: All substitute parts are rated MSL 1 (Unlimited), indicating unlimited shelf life without moisture control requirements. This matches the MSL 1 rating of the original AD8052ARM.
