AD7495ARMZ from Analog Devices, in a MSOP-8. 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 | REF OUT | power_out | Reference output for the AD7495 requires a minimum 100 nF capacitance to GND, and buffering is required before the internal reference is applied elsewhere in the system. |
| 2 | VIN | power_in | Single-ended analog input channel with an input range of 0 to REF IN. |
| 3 | GND | power_in | Analog ground reference point for all circuitry; all analog input signals and any external reference signal are referred to this voltage. |
| 4 | SCLK | input | Serial clock logic input that provides the serial clock for accessing data and is also the clock source for the conversion process. |
| 5 | SDATA | output | Serial data output carrying four leading zeros followed by the 12 conversion bits MSB first, clocked out on the falling edge of SCLK. |
| 6 | VDRIVE | power_in | Logic power supply input that sets the operating voltage of the serial interface. |
| 7 | CS | input | Active-low chip select logic input that initiates conversions and frames the serial data transfer. |
| 8 | VDD | power_in | Power supply input with a VDD range of 2.7 V to 5.25 V. |
