The part contains an internal conversion clock, error correction circuits, and both serial and parallel system interface ports. The AD7660 is hardware factory calibrated and is prehensively tested to ensure such ac parameters as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity. It is fabricated using Analog Devices’ high-performance, 0.6 micron CMOS process with correspondingly low cost, and is available in a 48-lead LQFP with operation specified from - 40°C to +85°C. 1. Fast Throughput The AD7660 is a 100 k SPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry. 2. Superior INL The AD7660 has a maximum integral nonlinearity of 3 LSBs with no missing 16-bit code. 3. Single-Supply Operation The AD7660 operates from a single 5 V supply and only dissipates 21 m W typical. Its power...
