Product Details
●The AD7660 is a 16-bit, 100 kSPS, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. 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 comprehensively tested to ensure ac parameters such 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 and a tiny 48-lead LFCSP with operation specified from –40°C to +85°C.
●Product Highlights
● 1. Fast throughput
●The AD7660 is a 100 kSPS, 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 µW typical. Its power dissipation decreases with the throughput to, for instance, only 21 µW at a 100 SPS throughput. It consumes 7 µW maximum when in power-down.
● 4. Serial or parallel interface
●Versatile parallel or 2-wire serial interface arrangement compatible with both 3 V or 5 V logic.
