# ADC128S052CIMT

**Texas Instruments** · Analog To Digital Converters (ADC) · TSSOP-16

ADC128S052CIMT 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 | CS | input | Chip select: a conversion begins on the falling edge of CS and continues as long as CS is held low. |
| 2 | VA | power_in | Positive analog supply, also used as the reference voltage, must be a quiet 2.7 V to 5.25 V source bypassed to GND with 1 µF and 0.1 µF ceramic capacitors within 1 cm of the pin. |
| 3 | AGND | power_in | Ground return for the analog supply and signals. |
| 4 | IN0 | input | Analog input, which can range from 0 V to VREF. |
| 5 | IN1 | input | Analog input, which can range from 0 V to VREF. |
| 6 | IN2 | input | Analog input, which can range from 0 V to VREF. |
| 7 | IN3 | input | Analog input, which can range from 0 V to VREF. |
| 8 | IN4 | input | Analog input, which can range from 0 V to VREF. |
| 9 | IN5 | input | Analog input, which can range from 0 V to VREF. |
| 10 | IN6 | input | Analog input, which can range from 0 V to VREF. |
| 11 | IN7 | input | Analog input, which can range from 0 V to VREF. |
| 12 | DGND | power_in | Ground return for the digital supply and signals. |
| 13 | VD | power_in | Positive digital supply, must be connected to a 2.7 V to VA supply and bypassed to GND with a 0.1 µF ceramic capacitor within 1 cm of the pin. |
| 14 | DIN | input | Digital data input, loading the control register on the rising edges of SCLK. |
| 15 | DOUT | output | Digital data output, clocking the output samples out on the falling edges of SCLK. |
| 16 | SCLK | input | Digital clock input with an ensured performance range of 3.2 MHz to 8 MHz, directly controlling the conversion and readout processes. |
