OPA2743EA

Texas Instruments · Operational Amplifier · VSSOP-8

OPA2743EA from Texas Instruments, in a VSSOP-8. 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, which swings to within 100mV of the rails at light load and sources or sinks up to ±20mA with
2 -In A input Inverting input of amplifier A; the input terminals are diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be current-limited to 10mA or less.
3 +In A input Noninverting input of amplifier A, with a common-mode voltage range of (V-) - 0.1V to (V+) + 0.1V.
4 V- power_in Negative power supply; the part is specified for 3.5V to 12V single supply or ±1.75V to ±6V dual supplies, with a 13.2V absolute maximum from V+ to V-.
5 +In B input Noninverting input of amplifier B, with a common-mode voltage range of (V-) - 0.1V to (V+) + 0.1V.
6 -In B input Inverting input of amplifier B; the input terminals are diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be current-limited to 10mA or less.
7 Out B output Output of amplifier B, which swings to within 100mV of the rails at light load and sources or sinks up to ±20mA with
8 V+ power_in Positive power supply; the part is specified for 3.5V to 12V single supply or ±1.75V to ±6V dual supplies, with a 13.2V absolute maximum from V+ to V-.
