GENERAL DESCRIPTION
Simultaneous/ AD7654 The AD7660 is a 16-bit, 100 kSPS, charge redistribution SAR, Multichannel AD7655 analog-to-digital converter that operates from a single 5 V power supply. The part contains an internal conversion clock, error cor- rection circuits, and both serial and parallel system interface ports.
PRODUCT HIGHLIGHTS
1. Fast Throughput The AD7660 is hardware factory-calibrated and is comprehen- The AD7660 is a 100 kSPS, charge redistribution, 16-bit sively tested to ensure ac parameters such as signal-to-noise ratio SAR ADC with internal error correction circuitry. (SNR) and total harmonic distortion (THD), in addition to the 2. Superior INL more traditional dc parameters of gain, offset, and linearity. The AD7660 has a maximum integral nonlinearity of 3 LSBs It is fabricated using Analog Devices’ high performance, with no missing 16-bit code. 0.6 micron CMOS process with correspondingly low cost and is 3. Single-Supply Operation available in a 48-lead LQFP and a tiny 48-lead LFCSP with The AD7660 operates from a single 5 V supply and only operation specified from –40∞C to +85∞C. dissipates 21 mW typical. Its power dissipation decreases with the throughput to, for instance, only 21 mW at a 100 SPS throughput. It consumes 7 mW maximum when in power-down. 4. Serial or Parallel Interface Versatile parallel or 2-wire serial interface arrangement com- patible with both 3 V or 5 V logic. REV.
