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). |
