TL3474IPWR

Texas Instruments · Operational Amplifier · TSSOP-14

TL3474IPWR 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 1OUT output Output of channel 1 (the datasheet gives no separate output limit for this pin beyond the absolute maximum output current of ±80 mA).
2 1IN- input Inverting input of channel 1, which must stay between VCC- and VCC+ (absolute maximum) with input current limited to ±1 mA.
3 1IN+ input Non-inverting input of channel 1, whose common-mode range extends down to VCC- (ground in single-supply use).
4 VCC+ power_in Positive supply voltage pin; the recommended total supply VCC± is 4 V to 36 V.
5 2IN+ input Non-inverting input of channel 2, whose common-mode range extends down to VCC- (ground in single-supply use).
6 2IN- input Inverting input of channel 2, which must stay between VCC- and VCC+ (absolute maximum) with input current limited to ±1 mA.
7 2OUT output Output of channel 2 (the datasheet gives no separate output limit for this pin beyond the absolute maximum output current of ±80 mA).
8 3OUT output Output of channel 3 (the datasheet gives no separate output limit for this pin beyond the absolute maximum output current of ±80 mA).
9 3IN- input Inverting input of channel 3, which must stay between VCC- and VCC+ (absolute maximum) with input current limited to ±1 mA.
10 3IN+ input Non-inverting input of channel 3, whose common-mode range extends down to VCC- (ground in single-supply use).
11 VCC-/GND power_in Negative supply voltage pin or ground for single-supply operation; the common-mode input range includes this pin.
12 4IN+ input Non-inverting input of channel 4, whose common-mode range extends down to VCC- (ground in single-supply use).
13 4IN- input Inverting input of channel 4, which must stay between VCC- and VCC+ (absolute maximum) with input current limited to ±1 mA.
14 4OUT output Output of channel 4 (the datasheet gives no separate output limit for this pin beyond the absolute maximum output current of ±80 mA).
