# OPA838SIDCKR

**Texas Instruments** · Operational Amplifier · SC-70-6

OPA838SIDCKR from Texas Instruments, in a SC-70-6. 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 | VOUT | output | Amplifier output; rail-to-rail output swings to within about 100 mV of the supply rails under light load, and output current is limited by the datasheet's saturated and linear output current figures. |
| 2 | VS- | power_in | Negative supply input; for single-supply use it is tied to ground, and the total supply range VS+ to VS- is 2.7 V to 5.4 V (absolute maximum 5.5 V). |
| 3 | VIN+ | power_in | Non-inverting input; the linear input common-mode range runs from VS- (about 0 V in single supply) to within about 1.3 V of VS+ at 25°C. |
| 4 | VIN- | power_in | Inverting input; the input voltage must stay within the absolute maximum range of VS- - 0.5 V to VS+ + 0.5 V, and in inverting configurations the reference voltage must be within the common-mode input range. |
| 5 | PD | input | Power-down control referenced to VS-: driving it low (at or below VS- + 0.55 V) disables the amplifier, driving it high (at or above VS- + 1.5 V) enables it, and it must be actively driven rather than left floating. |
| 6 | VS+ | power_in | Positive supply input; operating supply range is 2.7 V to 5.4 V with absolute maximum 5.5 V. |
