The AD7896 is a fast, 12-bit ADC which operates from a single +2.7 V to 5.5 V supply and is housed in a small 8-pin mini-DIP and 8-pin SOIC. The part contains an 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 AD7896 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, full-scale and offset errors, the AD7896 is also specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio. The part accepts an analog input range of 0 V to VDD and operates from a single +2.7 V to +5.5 V supply consuming only 9 mW typical. The VDD input is also used as the reference for the part so that no external reference is required. The AD7896 features a high sampling rate mode and, for low power applications, a proprietary automatic power down mode where the part automatically goes into power down once con-version is complete and "wakes up" before the next conversion cycle. The part is available in a small, 8-pin, 0.3" wide, plastic or hermetic dual-in-line package (mini-DIP) and in an 8-pin, small outline IC (SOIC).
