OPA4344UA

Texas Instruments · Operational Amplifier · SOIC-14

OPA4344UA 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 Amplifier A rail-to-rail output (within 1mV of the rails at 100kΩ load), with short-circuit current of ±15mA.
2 -In A input Amplifier A inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
3 +In A input Amplifier A non-inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
4 +V power_in Positive supply (V+), operating range 2.5V to 5.5V single supply, 7.5V absolute maximum between V+ and V-.
5 +In B input Amplifier B non-inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
6 -In B input Amplifier B inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
7 Out B output Amplifier B rail-to-rail output (within 1mV of the rails at 100kΩ load), with short-circuit current of ±15mA.
8 Out C output Amplifier C rail-to-rail output (within 1mV of the rails at 100kΩ load), with short-circuit current of ±15mA.
9 -In C input Amplifier C inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
10 +In C input Amplifier C non-inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
11 -V power_in Negative supply (V-) or ground in single-supply operation; the input and output ranges are referenced to this rail.
12 +In D input Amplifier D non-inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
13 -In D input Amplifier D inverting input, with common-mode range of -0.3V to (V+)+0.3V and diode-clamped to the supply rails (limit current to 10mA).
14 Out D output Amplifier D rail-to-rail output (within 1mV of the rails at 100kΩ load), with short-circuit current of ±15mA.
