## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN1 | input | Multiplexer analog input channel 1 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 2 | IN2 | input | Multiplexer analog input channel 2 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 3 | IN3 | input | Multiplexer analog input channel 3 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 4 | IN4 | input | Multiplexer analog input channel 4 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 5 | IN5 | input | Multiplexer analog input channel 5 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 6 | IN6 | input | Multiplexer analog input channel 6 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 7 | IN7 | input | Multiplexer analog input channel 7 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
| 8 | RESET | input | External reset input, active low. |
| 9 | EOC/INT/CDI | bidirectional | Programmable status output (EOC low during conversion by default, or INT low after conversion until FS/CS goes low, polarity programmable) that can also act as chain data input CDI in daisy-chain mode. |
| 10 | SCLK | input | SPI clock for the serial interface. |
| 11 | FS/CS | input | Frame sync signal for DSP (such as TMS320) or chip select input for SPI. |
| 12 | SDI | input | SPI serial data input. |
| 13 | SDO | output | SPI serial data output. |
| 14 | DGND | power_in | Digital interface ground. |
| 15 | CONVST | input | Conversion start input that freezes the sample-and-hold and starts the conversion. |
| 16 | VBD | power_in | Digital interface supply, 1.65 V minimum to VA + 0.2 V maximum (recommended operating conditions). |
| 17 | VA | power_in | Analog supply, 2.7 V to 5.5 V. |
| 18 | REF+ | input | External reference input. |
| 19 | REF- | power_in | External reference ground, to be connected to AGND through an individual via on the printed-circuit board. |
| 20 | AGND | power_in | Analog ground. |
| 21 | ADCIN | input | ADC input to the converter, with the absolute maximum range of -0.3 V to VA + 0.3 V to AGND. |
| 22 | MUXOUT | output | Multiplexer output. |
| 23 | COM | input | Common ADC input, usually connected to AGND; absolute maximum range is -0.3 V to 0.3 V to AGND. |
| 24 | IN0 | input | Multiplexer analog input channel 0 of the ADS8332 8-channel mux; inputs must stay within -0.3 V to VA + 0.3 V with respect to AGND (absolute maximum ratings). |
