Manufactured by Analog Devices - Part # AD7895ANZ-3 - PDIP8 Package

DESCRIPTION

The AD7895 is a fast 12-bit ADC that operates from a single +5 V supply and is housed in a small 8-pin mini-DIP and 8-pin SOIC. The part contains a 3.8 µs successive approximation A/D converter, an on-chip track/hold amplifier, an on-chip clock and a high speed serial interface.

Output data from the AD7895 is provided via a high speed, serial interface port. This two-wire serial interface has a serial clock input and a serial data output with the external serial clock accessing the serial data from the part.

In addition to the traditional dc accuracy specifications such as linearity and full-scale and offset errors, the AD7895 is specified for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio.
