# OPA842IDBVR

**Texas Instruments** · Operational Amplifier · SOT-23-5

OPA842IDBVR from Texas Instruments, in a SOT-23-5. 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 | Output | output | Op-amp output. Drives up to +/-90mA (typ at RL=100 ohm) with output swing typically +/-3.0V on +/-5V supplies. |
| 2 | -Vs | power_in | Negative power supply pin. Nominal -5V (specified range +/-5V; operating range +/-3.5V to +/-6V). Bypass locally to ground. |
| 3 | Noninverting Input | input | Noninverting (+) op-amp input. Common-mode input range +/-3.0V typical on +/-5V supplies; input bias current typically -35uA. |
| 4 | Inverting Input | input | Inverting (-) op-amp input. Used with feedback network (RF typical 402 ohm for G=+2) to set closed-loop gain. |
| 5 | +Vs | power_in | Positive power supply pin. Nominal +5V (specified range +/-5V; operating range +/-3.5V to +/-6V). Bypass locally to ground. |

## CAD (KiCad official)

- Symbol: `OPA842IDBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `opa842idbvr-etched.step` / `opa842idbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa842idbvr.step` / `opa842idbvr.glb` are the bare package body.
