OPA4342EA

Texas Instruments · Operational Amplifier · TSSOP-14

OPA4342EA from Texas Instruments, in a TSSOP-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 D output Output of amplifier D, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground.
2 -In D input Inverting input of amplifier D; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA.
3 +In D input Non-inverting input of amplifier D; the common-mode voltage range extends 300mV beyond the supply rails.
4 +V power_in Negative power supply (single-supply ground); the specified supply range is 2.7V to 5.5V across V+ to V-, with an absolute maximum of 7.5V.
5 +In C input Non-inverting input of amplifier C; the common-mode voltage range extends 300mV beyond the supply rails.
6 -In C input Inverting input of amplifier C; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA.
7 Out C output Output of amplifier C, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground.
8 Out A output Output of amplifier A, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground.
9 -In A input Inverting input of amplifier A; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA.
10 +In A input Non-inverting input of amplifier A; the common-mode voltage range extends 300mV beyond the supply rails.
11 +V power_in Positive power supply; the specified supply range is 2.7V to 5.5V across V+ to V-, with an absolute maximum of 7.5V.
12 +In B input Non-inverting input of amplifier B; the common-mode voltage range extends 300mV beyond the supply rails.
13 -In B input Inverting input of amplifier B; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA.
14 Out B output Output of amplifier B, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground.
