AD7895BRZ-10

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

AD7895BRZ-10 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 REF IN input Voltage reference input, buffered on chip, with a nominal reference voltage of +2.5 V for correct operation of the AD7895.
2 VIN power_in Analog input channel with an input range of ±10 V (AD7895-10), ±2.5 V (AD7895-3) and 0 V to +2.5 V (AD7895-2).
3 GND power_in Analog ground serving as the ground reference for the track/hold, comparator, digital circuitry and DAC.
4 SCLK input Serial clock input; a new serial data bit is clocked out on its falling edge, data is guaranteed valid for 10 ns after the falling edge, and the clock should be taken low at the end of serial data transmission.
5 SDATA output Serial data output providing sixteen bits (four leading zeros followed by 12 bits of conversion data), which is three-stated after the sixteenth falling edge of SCLK.
6 BUSY output Goes high on the falling edge of CONVST to indicate a conversion is in progress and returns low when the conversion is complete.
7 CONVST input Edge-triggered convert start input; its falling edge puts the track/hold into hold mode and initiates conversion, and if it is low at the end of conversion the part enters power-down, with a rising edge waking the part.
8 VDD power_in Positive supply voltage of +5 V ± 5%.
