OPA1641AIDGKR

Texas Instruments · Audio Amplifiers · VSSOP-8

OPA1641AIDGKR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection.
2 -IN input Inverting input with input bias current of ±20 pA maximum and common-mode input voltage range of (V-)-0.1 V to (V+)-3.5 V.
3 +IN input Noninverting input with input bias current of ±20 pA maximum and common-mode input voltage range of (V-)-0.1 V to (V+)-3.5 V.
4 V- power_in Negative (lowest) power supply with recommended operating range of ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply.
5 NC unconnected No internal connection.
6 OUT output Output with rail-to-rail swing from (V-)+0.2 to (V+)-0.2 V at RL=10kΩ or (V-)+0.35 to (V+)-0.35 V at RL=2kΩ, output current limits: 36 mA source and 30 mA sink.
7 V+ power_in Positive (highest) power supply with recommended operating range of ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply.
8 NC unconnected No internal connection.
