AD7896ARZ

Analog Devices · Analog To Digital Converters (ADCs) · SOIC-8

AD7896ARZ from Analog Devices, in a SOIC-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 VIN power_in Analog input with an input range of 0 V to VDD.
2 VDD power_in Positive supply voltage, 2.7 V to 5.5 V, also used as the reference for the part.
3 AGND power_in Analog ground, the ground reference for the track-and-hold, comparator, and DAC.
4 SCLK input Serial clock input that clocks out a new serial data bit on each falling edge, with data valid for 10 ns after the falling edge; it should be taken low at the end of the serial data transmission.
5 SDATA tri_state Serial data output providing sixteen bits (four leading zeros then 12 bits of straight binary conversion data) clocked out on SCLK falling edges, and three-stated after the 16th falling edge.
6 DGND power_in Digital ground, the ground reference for digital circuitry.
7 CONVST input Edge-triggered convert start input; the falling edge puts the track-and-hold in hold mode and starts conversion, if low at end of conversion the part powers down, and the rising edge wakes it up.
8 BUSY output Busy indicator that goes high on the falling edge of CONVST and returns low when the conversion is complete.
