ADS7280IPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +VA | power_in | Analog power supply input rated 2.7V to 5.5VDC. |
| 2 | +IN1 | input | Second noninverting analog input channel for dual-channel operation. |
| 3 | +IN0 | input | First noninverting analog input channel, 0V to VREF range. |
| 4 | COM | input | Common inverting input for both analog channels, typically connected to ground. |
| 5 | AGND | power_in | Analog ground reference. |
| 6 | REF- | input | Negative reference input; connect to AGND through individual via. |
| 7 | REF+ (REFIN) | input | External voltage reference input with range 0.3V to +VA V. |
| 8 | NC | unconnected | No internal connection. |
| 9 | CONVST | input | Conversion start trigger input that freezes sample-and-hold with minimum pulse duration 40ns low. |
| 10 | EOC/INT/CDI | bidirectional | Status output programmed as EOC (low when conversion in progress), INT (low pulse after conversion), or chain data input CDI in daisy-chain mode. |
| 11 | FS/CS | input | Frame sync signal for TMS320 DSP serial interface or chip select input for SPI interface. |
| 12 | SDI | input | Serial data input for configuration and conversion start/reset commands. |
| 13 | SDO | output | Serial data output tri-stated when FS/CS is high. |
| 14 | BDGND | power_in | Digital interface ground reference. |
| 15 | SCLK | input | Serial clock input supporting DC to 50MHz frequency. |
| 16 | +VBD | power_in | Digital interface power supply rated 1.65V to 5.5VDC. |
