LMP91051MT 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 | IN1 | input | Analog signal input for channel 1 of the dual-channel programmable gain amplifier. |
| 2 | IN2 | input | Analog signal input for channel 2 of the dual-channel programmable gain amplifier. |
| 3 | CMOUT | output | Analog common mode voltage output, which is set to 1.15 V or 2.59 V by the common mode generator. |
| 4 | A0 | output | First stage output, used for external filtering (high pass, low pass or band pass) to remove out-of-band noise. |
| 5 | A1 | input | Second stage input, used for external filtering (high pass, low pass or band pass) to remove out-of-band noise. |
| 6 | GND | power_in | Power ground. |
| 7 | NC | unconnected | No connect. |
| 8 | NC | unconnected | No connect. |
| 9 | OUT | output | Signal output, referenced to the same potential as CMOUT. |
| 10 | CSB | input | Digital chip select input, active low. |
| 11 | SCLK | input | Digital SPI interface clock input. |
| 12 | SDIO | bidirectional | Digital serial data input/output for the SPI interface. |
| 13 | VIO | power_in | Digital input/output supply, specified from 2.7 V to 5.5 V. |
| 14 | VDD | power_in | Positive analog supply, specified from 2.7 V to 5.5 V. |
