The AD7883 is a high speed, low power, 12-bit A/D converter which operates from a single +3 V to +3.6 V supply. It consists of a 5 µs track/hold amplifier, a 15 µs successive-approximation ADC, versatile interface logic and a multiple-input-range circuit. The part also includes a power save feature.
Fast bus access times and standard control inputs ensure easy interfacing to modern microprocessors and digital signal processors.
The AD7883 features a total throughput time of 20 µs and can convert full power signals up to 25 kHz with a sampling frequency of 50 kHz.
In addition to the traditional dc accuracy specifications such as linearity, full-scale and offset errors, the AD7883 is also fully specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio.
The AD7883 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 24-pin, 0.3 inch-wide, plastic dual-in-line package (DIP) as well as a small 24-lead SOIC package.
