|---|---|---|---|---|
| FFF Compatibility | The AD8651ARZ has the exact same pin assignments as the OPA350UA in an 8-SOIC package, with NC pins on 1, 5, and 8.Both parts share the identical standard 8-SOIC (0.154 in width, 3.90 mm) surface mount footprint.Meets or exceeds most electrical specifications. The only minor trade-off is a slightly higher supply current and a 2.7 V minimum operating voltage compared to 2.5 V. | Shares the identical pin assignments (Pin 1, 5, and 8 are No Connect) as the OPA350UA in the 8-SOIC package.Both parts utilize the standard 8-SOIC surface-mount package.While offering much higher bandwidth and speed, it trades off precision with a higher maximum input offset voltage of 2 mV vs 150 µV and a higher supply current of 8.3 mA vs 5.2 mA. | ||
 AI Summary | OPA350UA by Texas Instruments: Standard (General Purpose) Amplifier 1 Circuit Rail-to-Rail 8-SOIC. | The AD8651ARZ is an active, high-performance CMOS operational amplifier from Analog Devices that serves as an excellent replacement for the end-of-life OPA350UA. It provides a superior slew rate, larger bandwidth, and lower offset voltage, making it a reliable precision upgrade. It shares the identical SOIC-8 footprint and pinout for true drop-in compatibility.
| The OPA356AID is an active, high-speed CMOS replacement option from Texas Instruments that offers a substantial boost in bandwidth and slew rate. Since the OPA350UA is under Last Time Buy status, the OPA356AID represents a highly reliable, active TI alternative that remains completely pin-compatible. However, its offset voltage and supply current are higher, which may impact precision DC applications.
