Substitute Part Grouping Explanation

The ADA4622-1BRZ qualifies for direct substitution with the ADA4622-1ARZ based on strict parametric equivalence within the ADA4622 base product family. Both devices share identical electrical specifications across all critical performance parameters: J-FET amplifier topology, single-circuit configuration, rail-to-rail output, 23V/µs slew rate, 8 MHz gain bandwidth product, 15.5 MHz -3dB bandwidth, 2 pA input bias current, 715 µA supply current, 20 mA output current per channel, and 5V to 30V supply voltage range. Both devices operate across the -40°C to 125°C temperature range, utilize identical 8-SOIC surface mount packaging, and maintain equivalent compliance certifications (RoHS3, MSL 1, REACH Unaffected, EAR99).

The substitution relationship is determined by the following key parameters:

• Amplifier Type: J-FET
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 125°C
• Supply Voltage Range: 5V to 30V
• Slew Rate: 23V/µs
• Gain Bandwidth Product: 8 MHz

Parameter Comparison

Engineering Selection Recommendations

Both the ADA4622-1BRZ and ADA4622-1ARZ are Active products from Analog Devices Inc. with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), qualifying both for use in equivalent applications. The devices are electrically and mechanically interchangeable across all specified parameters with the exception of input offset voltage specification.

The ADA4622-1ARZ provides superior input offset voltage performance at 40 µV compared to the ADA4622-1BRZ at 400 µV. This specification difference represents a tighter tolerance grade within the same product family. Selection between these devices depends on application-specific offset voltage requirements. Both devices maintain identical supply voltage ranges (5V to 30V), operating temperature range (-40°C to 125°C), slew rate (23V/µs), gain bandwidth product (8 MHz), and output current capability (20 mA per channel).

Both parts are available in Active status with equivalent compliance certifications (REACH Unaffected, EAR99 classification). The ADA4622-1ARZ currently maintains higher inventory availability (2991 Pcs) compared to the ADA4622-1BRZ (2253 Pcs), which may influence supply chain decisions.
