Key Parameters

Substitute Part Grouping Explanation

Substitute components for the OPA699IDG4 are identified based on strict electrical and mechanical parameter compatibility within the voltage feedback amplifier category. The substitution logic is based on the following criteria:

Primary Compatibility Criteria:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 1
• Package / Case: 8-SOIC surface mount
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Range: Minimum 5 V to Maximum 12 V
• RoHS3 Compliance

Secondary Performance Parameters:

• Slew Rate: 1400 V/µs (OPA699IDG4 specification)
• Gain Bandwidth Product: 1 GHz (OPA699IDG4 specification)
• -3dB Bandwidth: 260 MHz (OPA699IDG4 specification)
• Current - Output / Channel: 120 mA (OPA699IDG4 specification)

Substitute parts must maintain the 8-SOIC package footprint and surface mount configuration to ensure direct PCB compatibility. All identified substitutes operate within the specified temperature and supply voltage ranges.

Parameter Comparison

Engineering Selection Recommendations

OPA699ID (Texas Instruments)

The OPA699ID is the direct equivalent substitute for the OPA699IDG4. Both devices share identical electrical specifications, including 1400 V/µs slew rate, 1 GHz gain bandwidth product, 260 MHz -3dB bandwidth, and 120 mA output current per channel. The OPA699ID maintains the same 8-SOIC package configuration and operating temperature range. This part is currently in active production status with higher inventory availability (1108 pcs) compared to the discontinued OPA699IDG4. The OPA699ID carries ROHS3 compliance and identical moisture sensitivity rating (MSL 2, 1 Year). This substitute provides direct functional and mechanical compatibility with no design modifications required.

AD8036ARZ-REEL7 (Analog Devices Inc.)

The AD8036ARZ-REEL7 is an alternative voltage feedback amplifier in the 8-SOIC package suitable for applications where the OPA699IDG4 specifications can accommodate minor parameter variations. The AD8036ARZ-REEL7 operates within the same temperature range (-40°C to 85°C) and shares the 8-SOIC surface mount package footprint. Key differences include: slew rate of 1200 V/µs (200 V/µs lower than OPA699IDG4), -3dB bandwidth of 240 MHz (20 MHz lower), input bias current of 4 µA (1 µA higher), input offset voltage of 2 mV (0.5 mV higher), supply current of 20.5 mA (5 mA higher), and output current of 70 mA per channel (50 mA lower). The AD8036ARZ-REEL7 requires minimum supply voltage of 6 V (1 V higher than OPA699IDG4). This device carries ROHS3 compliance and superior moisture sensitivity rating (MSL 1, Unlimited). The AD8036ARZ-REEL7 is supplied in Tape & Reel packaging format with higher inventory availability (3200 pcs).

Frequently Asked Questions (FAQ)

Q: Can the OPA699ID be used as a direct replacement for the OPA699IDG4?

A: Yes. The OPA699ID is the direct equivalent substitute. Both parts share identical electrical specifications, package configuration (8-SOIC), and operating parameters. The OPA699ID is currently in active production status, making it the recommended substitute for discontinued OPA699IDG4 applications.

Q: What are the key differences between the OPA699IDG4 and AD8036ARZ-REEL7?

A: The AD8036ARZ-REEL7 differs in several electrical parameters: slew rate is 1200 V/µs versus 1400 V/µs, -3dB bandwidth is 240 MHz versus 260 MHz, output current per channel is 70 mA versus 120 mA, and minimum supply voltage is 6 V versus 5 V. The AD8036ARZ-REEL7 has higher input bias current (4 µA versus 3 µA) and higher input offset voltage (2 mV versus 1.5 mV). Both devices use the same 8-SOIC package and operate across the same temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The OPA699ID and AD8036ARZ-REEL7 are both ROHS3 compliant, matching the compliance status of the OPA699IDG4.

Q: What is the difference in packaging between OPA699ID and AD8036ARZ-REEL7?

A: The OPA699ID is supplied in Tube packaging, while the AD8036ARZ-REEL7 is supplied in Tape & Reel (TR) format. Both devices use the same 8-SOIC (0.154", 3.90mm Width) package case for surface mount applications. The packaging format affects handling and automated assembly processes but does not impact electrical compatibility or PCB footprint.

Q: Can the AD8036ARZ-REEL7 be used in applications requiring 120 mA output current?

A: No. The AD8036ARZ-REEL7 is rated for 70 mA output current per channel, which is 50 mA lower than the OPA699IDG4 specification of 120 mA. Applications requiring the full 120 mA output current must use the OPA699ID substitute.

Q: What is the moisture sensitivity level difference between the substitutes?

A: The OPA699IDG4 and OPA699ID both have MSL 2 (1 Year) rating. The AD8036ARZ-REEL7 has a superior MSL 1 (Unlimited) rating, indicating lower moisture sensitivity and longer shelf life without baking requirements.

Q: Is the minimum supply voltage difference between OPA699IDG4 and AD8036ARZ-REEL7 significant?

A: The OPA699IDG4 operates at minimum 5 V supply, while the AD8036ARZ-REEL7 requires minimum 6 V. This 1 V difference may be significant in applications with tight supply voltage margins. Designs operating at 5 V supply must use the OPA699ID substitute rather than the AD8036ARZ-REEL7.
