OPA2835IDR

Texas Instruments · Operational Amplifier · SOIC-8

OPA2835IDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT1 output Amplifier 1 output. Rail-to-rail output stage, drives up to 40 mA typical continuous output current.
2 VIN1- input Amplifier 1 inverting input. Voltage-feedback op-amp input; input voltage range extends 0.2 V below VS- (negative-rail input).
3 VIN1+ input Amplifier 1 non-inverting input. Voltage-feedback op-amp input; input voltage range extends 0.2 V below VS- (negative-rail input).
4 VS- power_in Negative power supply input. Tie to GND for single-supply operation (2.5 V to 5.5 V across VS+/VS-) or to a negative rail for split-supply operation (±1.25 V to ±2.75 V).
5 VIN2+ input Amplifier 2 non-inverting input. Voltage-feedback op-amp input; input voltage range extends 0.2 V below VS- (negative-rail input).
6 VIN2- input Amplifier 2 inverting input. Voltage-feedback op-amp input; input voltage range extends 0.2 V below VS- (negative-rail input).
7 VOUT2 output Amplifier 2 output. Rail-to-rail output stage, drives up to 40 mA typical continuous output current.
8 VS+ power_in Positive power supply input. 2.5 V to 5.5 V (single-supply, referenced to VS-=GND) or +1.25 V to +2.75 V (split-supply). Bypass locally with 0.1 µF ceramic capacitor.
