# OPA684IDBVR

**Texas Instruments** · Operational Amplifier · SOT-23-6

OPA684IDBVR from Texas Instruments, in a SOT-23-6. 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 | Output | output | Amplifier output, rated for 120mA output current and a ±4VPP swing on ±5V supplies into 100Ω; goes high impedance when disabled. |
| 2 | -VS | power_in | Negative supply pin; the device operates on dual ±2.5 to ±6.0V supplies (absolute maximum ±6.5V) or a single +5V to +12V supply. |
| 3 | Noninverting Input | input | Noninverting amplifier input with 50kΩ || 2pF input impedance and a ±3.75V typical common-mode input range at ±5V supplies. |
| 4 | Inverting Input | input | Inverting input of the current-feedback amplifier, with a low open-loop input resistance of 2.5Ω typical that senses the feedback error current. |
| 5 | DIS | input | Disable control: leaving it open or holding it HIGH gives normal operation, while pulling it LOW cuts supply current to less than 100µA and puts the I/O pins in a high-impedance state. |
| 6 | +VS | power_in | Positive supply pin; the device operates on dual ±2.5 to ±6.0V supplies (absolute maximum ±6.5V) or a single +5V to +12V supply. |
