# OPA364AIDBVR

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

OPA364AIDBVR 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 | VOUT | output | Amplifier output; it swings to within about 10 mV of the supply rails at RL = 10 kΩ and 25°C, and 20 mV at −40°C to +125°C. |
| 2 | V- | power_in | Negative (lowest) power supply; the operating supply [V+] - [V-] is specified from 1.8 V to 5.5 V, with an absolute maximum of 5.5 V. |
| 3 | +IN | input | Positive (non-inverting) input; the common-mode range extends 100 mV beyond each supply rail, and input current is limited to 10 mA if the input is driven more than 0.5 V beyond a rail. |
| 4 | -IN | input | Negative (inverting) input; it shares the same 100 mV beyond-rail common-mode range and the same 10 mA input current limit as +IN. |
| 5 | V+ | power_in | Positive (highest) power supply; the operating supply [V+] - [V-] is specified from 1.8 V to 5.5 V, with an absolute maximum of 5.5 V. |
