# TS321QDBVRQ1

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

TS321QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 | OUT | output | Amplifier output; the datasheet states the output can be shorted to ground for an unlimited duration. |
| 2 | VCC- | power_in | Negative supply rail, which is GND in single-supply operation (VCC- = GND in the test conditions); the device supports single supply 3 V to 30 V or dual supply ±1.5 V to ±15 V. |
| 3 | IN+ | input | Non-inverting input; neither input may be driven more positive than VCC+ or more negative than VCC-, and the common-mode range is 0 V to VCC+ - 1.5 V, with no more than 0.3 V below VCC-. |
| 4 | IN- | input | Inverting input; neither input may be driven more positive than VCC+ or more negative than VCC-, and the common-mode range is 0 V to VCC+ - 1.5 V, with no more than 0.3 V below VCC-. |
| 5 | VCC+ | power_in | Positive supply rail; the absolute maximum supply voltage is 32 V and the recommended supply is 3 V to 30 V single supply or ±1.5 V to ±15 V dual supply. |
