ADS1242IPWT from Texas Instruments, in a TSSOP-16. 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 | VDD | power_in | Power supply, 2.7V to 5.25V supply range; absolute maximum VDD to GND is -0.3V to +6V. |
| 2 | XIN | input | Clock input; master clock rate is 1 to 5 MHz, and VIL for XIN is GND to GND + 0.05V. |
| 3 | XOUT | output | Clock output, used with a crystal or ceramic resonator. |
| 4 | PDWN | input | Active LOW power-down input; the power-down function shuts down the analog and digital circuits. |
| 5 | VREF+ | power_in | Positive differential reference input; reference input range is 0 to VDD, with VREF (REF IN+ minus REF IN-) of 0.1V to 1.25V (1.30V max) for RANGE = 0. |
| 6 | VREF- | power_in | Negative differential reference input; reference input range is 0 to VDD. |
| 7 | AIN0/D0 | bidirectional | Analog input 0 / data I/O 0; analog input range is GND - 0.1V to VDD + 0.1V with buffer OFF and GND + 0.05V to VDD - 1.5V with buffer ON, and the pin can be used as data input or output. |
| 8 | AIN1/D1 | bidirectional | Analog input 1 / data I/O 1; analog input range is GND - 0.1V to VDD + 0.1V with buffer OFF and GND + 0.05V to VDD - 1.5V with buffer ON, and the pin can be used as data input or output. |
| 9 | AIN2/D2 | bidirectional | Analog input 2 / data I/O 2; analog input range is GND - 0.1V to VDD + 0.1V with buffer OFF and GND + 0.05V to VDD - 1.5V with buffer ON, and the pin can be used as data input or output. |
| 10 | AIN3/D3 | bidirectional | Analog input 3 / data I/O 3; analog input range is GND - 0.1V to VDD + 0.1V with buffer OFF and GND + 0.05V to VDD - 1.5V with buffer ON, and the pin can be used as data input or output. |
| 11 | GND | power_in | Ground reference for the device. |
| 12 | CS | input | Active LOW chip select; DOUT goes tri-state immediately when CS goes HIGH. |
| 13 | DIN | input | Serial data input with Schmitt trigger input. |
| 14 | DOUT | output | Serial data output; goes tri-state immediately when CS goes HIGH. |
| 15 | SCLK | input | Serial clock input with Schmitt trigger input. |
| 16 | DRDY | output | Active LOW data-ready output. |
