AD7660ASTZRL

ADC Single SAR 100KSPS 16Bit Parallel/Serial 48Pin LQFP T/R

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.
