TLV2772AMDRG4 Equivalent & Substitute Parts

Part Overview

The TLV2772AMDRG4 is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for general-purpose amplification applications requiring low power consumption and wide supply voltage range. The TLV2772AMDRG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing circuit designs while meeting the same electrical and mechanical specifications.

Engineering Selection Recommendations

CMOS Amplifier Substitutes (AD8602 Series)

The AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, and AD8602WARZ-R7 are all manufactured by Analog Devices Inc. and represent the closest functional equivalents to the TLV2772AMDRG4. All four variants share identical electrical specifications and are part of the active DigiTrim® product line. These devices maintain CMOS amplifier architecture, dual-channel configuration, rail-to-rail output, and 8-SOIC packaging. The primary differences among these variants are packaging formats: tube, tape & reel, and cut tape with Digi-Reel®. All AD8602 variants are ROHS3 compliant with MSL 1 rating and are suitable for direct substitution in applications where the original TLV2772AMDRG4 was specified.

The AD8602 series exhibits higher gain bandwidth product (8.4 MHz versus 5.1 MHz) and lower input bias current (0.2 pA versus 2 pA) compared to the TLV2772AMDRG4. The minimum supply voltage is 2.7 V, which is 0.2 V higher than the original part. The operating temperature range is -40°C to 125°C, which does not extend to the original -55°C minimum. Applications requiring operation below -40°C must use alternative substitutes or the original TLV2772AMDRG4 if available from alternative sources.

General-Purpose Amplifier Substitutes

The LMV822IDT (STMicroelectronics), MAX4326ESA+ and MAX4326ESA+T (Analog Devices Inc./Maxim Integrated), MCP6282-E/SN and MCP6282T-E/SN (Microchip Technology), and MCP6482-E/SN (Microchip Technology) are general-purpose amplifiers that meet the core mechanical and electrical compatibility requirements. All devices feature dual-channel configuration, rail-to-rail output, and 8-SOIC packaging with MSL 1 rating.

The LMV822IDT is qualified to AEC-Q100 automotive standards and operates across -40°C to 125°C. The MAX4326 series extends the maximum supply voltage to 6.5 V but limits the maximum operating temperature to 85°C, making it unsuitable for applications requiring 125°C operation. The MCP6282 and MCP6482 series support the full -40°C to 125°C temperature range and offer lower minimum supply voltage (2.2 V). The MCP6482-E/SN provides the lowest supply current (240 µA per two channels) but delivers reduced output current per channel (12 mA) compared to the original specification (50 mA).

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the AD8602ARZ series be used as a direct replacement for the TLV2772AMDRG4?

A: The AD8602ARZ series provides functional equivalence in terms of package type, pin configuration, and core electrical specifications. However, the minimum operating temperature is -40°C rather than -55°C. If your application operates only within the -40°C to 125°C range, the AD8602 series is suitable for direct substitution. Applications requiring -55°C operation must use alternative parts or source the original TLV2772AMDRG4 from alternative suppliers.

Q: What is the difference between AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, and AD8602WARZ-R7?

A: These four part numbers represent the same device with identical electrical specifications but different packaging formats. AD8602ARZ is supplied in tube packaging. AD8602ARZ-REEL is supplied in tape & reel format. AD8602ARZ-REEL7 is supplied in cut tape with Digi-Reel® format. AD8602WARZ-R7 is also supplied in cut tape with Digi-Reel® format. Selection depends on your procurement and assembly requirements. All four variants are electrically and mechanically interchangeable.

Q: Why do some substitute parts have lower output current per channel than the TLV2772AMDRG4?

A: The MCP6282 series specifies 25 mA output current per channel, and the MCP6482 series specifies 12 mA per channel, both lower than the original 50 mA specification. These devices are suitable only for applications where the output current requirement does not exceed their rated limits. If your circuit requires 50 mA output current per channel, use the AD8602 series, LMV822IDT, or MAX4326 series, which all meet or exceed this specification.

Q: Is the LMV822IDT suitable for automotive applications?

A: The LMV822IDT is qualified to AEC-Q100 automotive standards and is designated as an automotive-grade device. If your application requires automotive qualification, the LMV822IDT is the appropriate choice among the substitute options. Other substitutes are not explicitly qualified to automotive standards.

Q: What is the impact of the higher gain bandwidth product in the AD8602 series?

A: The AD8602 series exhibits 8.4 MHz gain bandwidth product compared to 5.1 MHz in the TLV2772AMDRG4. This higher bandwidth provides improved frequency response and faster signal settling. In most applications, this represents an improvement. However, circuits designed with specific compensation networks or frequency response characteristics based on the original 5.1 MHz specification may require re-evaluation to ensure stability and performance remain within design margins.

Q: Can I use the MAX4326 series in applications requiring 125°C operation?

A: No. The MAX4326ESA+ and MAX4326ESA+T are rated only to 85°C maximum operating temperature. Applications requiring operation at 125°C must use the AD8602 series, LMV822IDT, MCP6282 series, or MCP6482 series, all of which support the full 125°C specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating, matching the original TLV2772AMDRG4 specifications.

Q: What is the significance of the 2.7 V minimum supply voltage in the AD8602 series versus 2.5 V in the TLV2772AMDRG4?

A: The AD8602 series requires a minimum supply voltage of 2.7 V, which is 0.2 V higher than the original 2.5 V specification. Applications operating at supply voltages between 2.5 V and 2.7 V cannot use the AD8602 series. For such applications, use the LMV822IDT (2.5 V minimum), MAX4326 series (2.4 V minimum), or MCP6282/MCP6482 series (2.2 V minimum).

Q: How do I select between the MCP6282 and MCP6482 series?

A: Both series are dual-channel, rail-to-rail amplifiers in 8-SOIC packaging. The MCP6282 provides 25 mA output current per channel and 450 µA supply current per two channels. The MCP6482 provides 12 mA output current per channel and 240 µA supply current per two channels. Select MCP6282 if your application requires higher output current. Select MCP6482 if power consumption is the primary concern and output current requirements do not exceed 12 mA per channel.
