# TLC2252AIPWR

**Texas Instruments** · Operational Amplifier · TSSOP-8

TLC2252AIPWR from Texas Instruments, in a TSSOP-8. 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 amplifier 1, which swings to both supply rails (rail-to-rail output). |
| 2 | 1IN- | input | Inverting input of amplifier 1; the common-mode input voltage range includes the negative rail. |
| 3 | 1IN+ | input | Non-inverting input of amplifier 1; the common-mode input voltage range includes the negative rail. |
| 4 | VDD-/GND | power_in | Negative supply rail (VDD- or GND); the part is specified for both single-supply and split-supply operation. |
| 5 | 2IN+ | input | Non-inverting input of amplifier 2; the common-mode input voltage range includes the negative rail. |
| 6 | 2IN- | input | Inverting input of amplifier 2; the common-mode input voltage range includes the negative rail. |
| 7 | 2OUT | output | Output of amplifier 2, which swings to both supply rails (rail-to-rail output). |
| 8 | VDD+ | power_in | Positive supply rail (VDD+) for the device. |
