OPA703NA

Texas Instruments · Operational Amplifier · SOT-23-5

OPA703NA 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, which swings to within 40mV of the rail (RL = 100kΩ) and sources or sinks ±10mA with
2 V- power_in Negative supply (ground in single-supply use); supply range V+ to V- is 4V to 12V specified, 13.2V absolute maximum.
3 +In input Non-inverting input, with common-mode range from (V-) - 0.3V to (V+) + 0.3V and diode-clamped to the supply rails (limit input current to 10mA).
4 -In input Inverting input, with common-mode range from (V-) - 0.3V to (V+) + 0.3V and diode-clamped to the supply rails (limit input current to 10mA).
5 V+ power_in Positive supply; specified for 4V to 12V single supply (±2V to ±6V dual), 13.2V absolute maximum between V+ and V-.
