ADI AD7893ANZ-5

The AD7893 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 6 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 AD7893 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 traditional dc accuracy specifications such as linearity, full-scale and offset errors, the AD7893 is also specified for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio. The part accepts an analog input range of ±10 V (AD7893-10), ±2.5 V (AD7893-3), 0 V to +5 V (AD7893-5) or 0 V to +2.5 V (AD7893-2) and operates from a single +5 V supply, consuming only 25 mW typical. The AD7893 is fabricated in Analog Devices’ Linear Compatible CMOS (LC²MOS) process, a mixed technology process that combines precision bipolar circuits with low power CMOS logic. 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).
