OPA388IDR

Texas Instruments · Operational Amplifier · SOIC-8

OPA388IDR 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 NC unconnected No internal connection. Can be left floating; may optionally be tied to any potential within the supply range for layout convenience.
2 -IN input Inverting analog input. True rail-to-rail input (V-)-0.5 V to (V+)+0.5 V absolute max common-mode; typical input bias currents are very low (chopper-stabilized front end). Differential input voltage limited to (V+)-(V-)+0.2 V; series input current must stay within ±10 mA.
3 +IN input Noninverting analog input. True rail-to-rail input with EMI/RFI filtering; common-mode range extends from (V-)-0.5 V to (V+)+0.5 V (absolute max). Same ±10 mA input current limit as -IN.
4 V- power_in Negative (lowest) power-supply rail. Ground in single-supply operation, or the negative rail in dual-supply operation. Total supply (V+)-(V-) must be 2.5 V to 5.5 V (absolute max 6 V single / ±3 V dual). Bypass with a 0.1 µF ceramic capacitor placed close to the pin.
5 NC unconnected No internal connection. Can be left floating.
6 OUT output Amplifier output. True rail-to-rail output stage swings to within a few millivolts of both supplies with a 10 kΩ load; short-circuit-to-ground is continuous. Typical output impedance is low and settles to 0.01% in ~2 µs for a 1 V step.
7 V+ power_in Positive (highest) power-supply rail. 2.5 V to 5.5 V single-supply relative to V-, or up to +2.75 V in dual-supply operation. Bypass with a 0.1 µF ceramic capacitor placed close to the pin.
8 NC unconnected No internal connection. Can be left floating.
