OPA310SIDCKR

TEXAS INSTRUMENTS · Global Sourcing Parts · SC-70-6(SOT-363)

OPA310SIDCKR from TEXAS INSTRUMENTS, in a SC-70-6(SOT-363). 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 IN+ input Noninverting input; the recommended input voltage range is -0.1 V to 5.6 V.
2 V- power_in Negative (low) supply or ground for single-supply operation; supply voltage (V+) - (V-) is 1.5 V to 5.5 V.
3 IN- input Inverting input.
4 OUT output Amplifier output.
5 SHDN input Shutdown: low = amplifier disabled, high = amplifier enabled; valid logic low is between V- and (V-) + 0.2 V, valid logic high is between (V-) + 1.2 V and V+, and the maximum voltage allowed is (V+) + 0.5 V.
6 V+ power_in Positive (high) supply; supply voltage (V+) - (V-) is 1.5 V to 5.5 V.
