ADS7853IPWR 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 | AINP_A | input | Positive analog input channel A; input voltage within configured full-scale range (0 to VREF single-ended, -VREF/2 to VREF/2 pseudo-differential). |
| 2 | AINM_A | input | Negative analog input channel A; externally connect to GND (single-ended) or FSR_ADC_A/2 (pseudo-differential). |
| 3 | REFIO_A | bidirectional | Reference voltage input/output channel A; 2.495 to 2.505 V internal reference or 2.4 to 2.5 V external, requires 10 µF bypass capacitor to REFGND_A. |
| 4 | REFGND_A | power_in | Reference ground potential channel A; return path for REFIO_A with 10 µF decoupling capacitor. |
| 5 | REFGND_B | power_in | Reference ground potential channel B; return path for REFIO_B with 10 µF decoupling capacitor. |
| 6 | REFIO_B | bidirectional | Reference voltage input/output channel B; 2.495 to 2.505 V internal reference or 2.4 to 2.5 V external, requires 10 µF bypass capacitor to REFGND_B. |
| 7 | AINM_B | input | Negative analog input channel B; externally connect to GND (single-ended) or FSR_ADC_B/2 (pseudo-differential). |
| 8 | AINP_B | input | Positive analog input channel B; input voltage within configured full-scale range (0 to VREF single-ended, -VREF/2 to VREF/2 pseudo-differential). |
| 9 | DVDD | power_in | Digital I/O supply voltage 1.65 to 5.5 V; provides power to digital interface circuitry with 10 µF bypass to GND. |
| 10 | SDI | input | Serial data input; receives configuration register, REFDAC_A, and REFDAC_B data during serial frames. |
| 11 | CS | input | Chip-select input (active low); defines start and end of serial interface frames with minimum 40 ns high time between frames. |
| 12 | SCLK | input | Serial clock input; synchronizes data transfers with frequency range 1 to 20 MHz for 32-CLK mode or 1 to 34 MHz for 16-CLK mode. |
| 13 | SDO_A | tri_state | Serial data output A (tri-state, high-Z when CS high); outputs ADC_A conversion result or both ADC_A and ADC_B results depending on interface mode. |
| 14 | SDO_B | tri_state | Serial data output B (tri-state, high-Z when CS high); outputs ADC_B conversion result in dual-SDO mode or remains high-Z in single-SDO mode. |
| 15 | GND | power_in | Digital ground; reference potential for digital circuitry and must connect to PCB ground plane. |
| 16 | AVDD | power_in | Analog supply voltage 4.5 to 5.5 V (internal reference) or 5.0 to 5.5 V (external reference); provides power to analog circuits with 10 µF bypass to GND. |
