OPA4314AIPWR

Texas Instruments · Operational Amplifier · TSSOP-14

OPA4314AIPWR 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 A	output	Output of amplifier A with rail-to-rail swing, typically within 5-20 mV from supply rails at 10 kΩ load.
2	-IN A	input	Inverting input of amplifier A, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
3	+IN A	input	Noninverting input of amplifier A, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
4	V+	power_in	Positive (highest) supply voltage, operating range 1.8 V to 5.5 V, absolute maximum 7 V.
5	+IN B	input	Noninverting input of amplifier B, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
6	-IN B	input	Inverting input of amplifier B, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
7	OUT B	output	Output of amplifier B with rail-to-rail swing, typically within 5-20 mV from supply rails at 10 kΩ load.
8	OUT C	output	Output of amplifier C with rail-to-rail swing, typically within 5-20 mV from supply rails at 10 kΩ load.
9	-IN C	input	Inverting input of amplifier C, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
10	+IN C	input	Noninverting input of amplifier C, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
11	V-	power_in	Negative (lowest) supply voltage reference, typically connected to ground in single-supply or negative rail in dual-supply operation.
12	+IN D	input	Noninverting input of amplifier D, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
13	-IN D	input	Inverting input of amplifier D, accepts common-mode voltage from (V-) - 0.2 V to (V+) + 0.2 V with input current limited to ±10 mA.
14	OUT D	output	Output of amplifier D with rail-to-rail swing, typically within 5-20 mV from supply rails at 10 kΩ load.
