OPA2990IDSGR

Texas Instruments · Operational Amplifier · WSON-8-EP(2x2)

OPA2990IDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 OUT1 output Output, channel 1; DC output with rail-to-rail swing capability within specified voltage margins per supply voltage (45-300mV at 40V, 5-50mV at 2.7V).
2 IN1- input Inverting input, channel 1; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V.
3 IN1+ input Non-inverting input, channel 1; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V.
4 V- power_in Negative (lowest) power supply rail; establishes analog ground reference and completes output current return path; typical supply range 2.7V to 40V above absolute minimum.
5 IN2+ input Non-inverting input, channel 2; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V.
6 IN2- input Inverting input, channel 2; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V.
7 OUT2 output Output, channel 2; DC output with rail-to-rail swing capability within specified voltage margins per supply voltage (45-300mV at 40V, 5-50mV at 2.7V).
8 V+ power_in Positive (highest) power supply rail; provides bias current and enables output stage amplification; typical supply range 2.7V to 40V above V-.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
