OPA4990IPWR

Texas Instruments · Operational Amplifier · TSSOP-14

OPA4990IPWR 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	OUT1	output	Output of amplifier channel 1; the short-circuit current is specified as ±80 mA.
2	IN1-	input	Inverting input of amplifier channel 1; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
3	IN1+	input	Non-inverting input of amplifier channel 1; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
4	V+	power_in	Positive (highest) power supply; the operating supply range is 2.7 V to 40 V (±1.35 V to ±20 V) and the absolute maximum is 42 V.
5	IN2+	input	Non-inverting input of amplifier channel 2; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
6	IN2-	input	Inverting input of amplifier channel 2; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
7	OUT2	output	Output of amplifier channel 2; the short-circuit current is specified as ±80 mA.
8	OUT3	output	Output of amplifier channel 3; the short-circuit current is specified as ±80 mA.
9	IN3-	input	Inverting input of amplifier channel 3; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
10	IN3+	input	Non-inverting input of amplifier channel 3; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
11	V-	power_in	Negative (lowest) power supply; the input and output voltage limits are referenced to this pin.
12	IN4+	input	Non-inverting input of amplifier channel 4; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
13	IN4-	input	Inverting input of amplifier channel 4; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
14	OUT4	output	Output of amplifier channel 4; the short-circuit current is specified as ±80 mA.
