# ADS8330IBPWR

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

ADS8330IBPWR 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 | +VA | power_in | Analog supply voltage, +2.7 V to +5.5 VDC. |
| 2 | +IN1 | input | Second noninverting analog input. |
| 3 | +IN0 | input | First noninverting analog input. |
| 4 | COM | input | Common inverting input, typically connected to ground. |
| 5 | AGND | power_in | Analog ground reference. |
| 6 | REF- | input | Reference negative input; connect to AGND via individual via. |
| 7 | REF+ | input | External reference positive input. |
| 8 | NC | unconnected | No connection. |
| 9 | CONVST | input | Conversion start input; triggers conversion with next rising edge of internal clock. |
| 10 | EOC/INT/CDI | tri_state | Status output programmable as end-of-conversion or interrupt; also functions as chain data input in daisy-chain mode. |
| 11 | FS/CS | input | Frame sync or chip select input for TMS320 DSP or SPI serial interface. |
| 12 | SDI | input | Serial data input enabling conversion start and reset commands. |
| 13 | SDO | tri_state | Serial data output. |
| 14 | BDGND | power_in | Digital interface ground reference. |
| 15 | SCLK | input | Serial interface clock input. |
| 16 | +VBD | power_in | Digital interface supply voltage. |
