The AD7880BNZ is a LC2MOS high speed, low power 12-bit Analog-to-digital Converter (ADC) which operates from a single 5V supply. It consists of a 3μs track/hold amplifier, a 12μs successive-approximation ADC, versatile interface logic and a multiple-input-range circuit. The part also includes a power save feature. An internal resistor network allows the part to accept both uni-polar and bipolar input signals. Fast bus access times and standard control inputs ensure easy interfacing to modern microprocessors and digital signal processors. It features a total throughput time of 15μs and can convert full power signals up to 33kHz with a sampling frequency of 66kHz. In addition to the traditional DC accuracy specifications such as linearity, full-scale and offset errors, the converter is also fully specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio.
