# ADS1203IPWT

**Texas Instruments** · Analog To Digital Converters (ADCs) · TSSOP-8

ADS1203IPWT 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 | M0 | input | Mode input that selects the ADS1203 operating mode; the datasheet gives no further limits for this pin. |
| 2 | VIN+ | power_in | Noninverting analog input; the differential input VIN+ − VIN− is specified from −250 mV to +250 mV for the TSSOP package. |
| 3 | VIN− | power_in | Inverting analog input forming the differential input VIN+ − VIN−, specified from −250 mV to +250 mV for the TSSOP package. |
| 4 | M1 | input | Mode input that selects the ADS1203 operating mode; the datasheet gives no further limits for this pin. |
| 5 | GND | power_in | Power supply ground; internally connected to both AGND and BGND in the TSSOP package. |
| 6 | MDAT | output | Modulator data output (bit stream), specified for a 30 pF load capacitance. |
| 7 | MCLK | bidirectional | Modulator clock input or output; the external clock is specified at 16 MHz to 24 MHz (20 MHz nominal), with reduced accuracy from 1 MHz up to 32 MHz. |
| 8 | VDD | power_in | Power supply pin, +5 V nominal (4.5 V to 5.5 V); internally connected to both AVDD and BVDD in the TSSOP package. |
