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 40C to +85C. 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.
