OPA4703UA

Texas Instruments · Operational Amplifier · SOIC-14

OPA4703UA from Texas Instruments, in a SOIC-14. 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 A output Output of amplifier A, rated for ±10 mA output current (
2 -In A input Inverting input of amplifier A; input terminals are diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be current-limited to 10 mA or less.
3 +IN A input Non-inverting input of amplifier A; the common-mode voltage range extends 0.3V beyond each rail, from (V-) - 0.3V to (V+) + 0.3V.
4 V+ power_in Positive supply; single supply 4V to 12V or dual supplies ±2V to ±6V, with an absolute maximum V+ to V- of 13.2V.
5 +IN B input Non-inverting input of amplifier B; the common-mode voltage range extends 0.3V beyond each rail, from (V-) - 0.3V to (V+) + 0.3V.
6 -In B input Inverting input of amplifier B; input terminals are diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be current-limited to 10 mA or less.
7 OUT B output Output of amplifier B, rated for ±10 mA output current (
8 OUT C output Output of amplifier C, rated for ±10 mA output current (
9 -In C input Inverting input of amplifier C; input terminals are diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be current-limited to 10 mA or less.
10 +IN C input Non-inverting input of amplifier C; the common-mode voltage range extends 0.3V beyond each rail, from (V-) - 0.3V to (V+) + 0.3V.
11 V- power_in Negative supply rail (V-); the absolute maximum V+ to V- is 13.2V and the specified dual-supply range is ±2V to ±6V.
12 +IN D input Non-inverting input of amplifier D; the common-mode voltage range extends 0.3V beyond each rail, from (V-) - 0.3V to (V+) + 0.3V.
13 -In D input Inverting input of amplifier D; input terminals are diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be current-limited to 10 mA or less.
14 OUT D output Output of amplifier D, rated for ±10 mA output current (
