ADS8512IBDW from Texas Instruments, in a SOIC-16-300mil. 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 | R1IN | input | Analog input whose connection to BUF, GND, or VIN sets the input range per Table 1 and Table 3, and the input may swing to ±25 V without damage. |
| 2 | GND | power_in | Ground connection; ground voltage differences are limited to ±0.3 V per the absolute maximum ratings. |
| 3 | R2IN | input | Analog input whose connection to BUF, GND, or VIN sets the input range per Table 1 and Table 3, and the input may swing to ±25 V without damage. |
| 4 | R3IN | input | Analog input whose connection to BUF, GND, or VIN sets the input range per Table 1 and Table 3, and the input may swing to ±25 V without damage. |
| 5 | BUF | output | Reference buffer output that is connected to R1IN, R2IN, or R3IN as needed for the selected input range. |
| 6 | CAP | passive | Reference buffer compensation node that should be decoupled to ground with a 1-µF tantalum capacitor in parallel with a 0.01-µF ceramic capacitor. |
| 7 | REF | bidirectional | Reference input/output that outputs the internal 2.5-V reference through a series 4-kΩ resistor, is decoupled with 1-µF to 2.2-µF tantalum to ground, and is overridden if an external reference is applied. |
| 8 | GND | power_in | Ground connection; ground voltage differences are limited to ±0.3 V per the absolute maximum ratings. |
| 9 | DATACLK | bidirectional | Serial data clock that is an output 3-stated when CS is high if EXT/INT is low, and an input requiring an externally supplied serial clock if EXT/INT is high. |
| 10 | DATA | output | Serial data output carrying the result of the last completed conversion, synchronized to DATACLK, and 3-stated when CS is high. |
| 11 | EXT/INT | input | Selects the DATACLK source: high requires an external serial clock, while low derives the clock from the internal conversion clock. |
| 12 | CONV | input | A falling edge places the sample/hold in hold, starts a conversion regardless of CS, and is ignored if a conversion is already in progress. |
| 13 | CS | input | Chip select that 3-states DATA, BUSY, and DATACLK (when EXT/INT is low) when high and enables all outputs when low. |
| 14 | BUSY | output | Goes low when a conversion starts and remains low through the conversion; it is 3-stated when CS is high. |
| 15 | PWRD | input | Power-down input that places the device in a low-power mode when high; CONV must be taken low first to achieve the lowest power consumption. |
| 16 | VS | power_in | +5-V supply input (4.75 V to 5.25 V) that should be decoupled to ground with a 0.1-µF ceramic capacitor in parallel with a 10-µF tantalum capacitor. |
