AD7663ASTZRL LQFP-48_ 7x7x05P lowest inventory clearing price

explain

The AD7663 is a 16 bit, 250 kSPS, charge redistribution SAR, analog to digital converter that operates from a 5V power supply. It includes a high-speed 16 bit sampling ADC, a resistive input expander that allows a variety of input ranges, an internal conversion clock, error correction circuits, and serial and parallel system interface ports.

The AD7663 is factory calibrated and has been comprehensively tested. In addition to the more traditional gain, offset and linearity, it also ensures the signal to noise ratio, SNR, total harmonic distortion (THD) and other AC parameters. It adopts the high performance of analog devices, and is manufactured with 0.6 μ m CMOS process. It can use 48 lead LQFP and micro 48 lead LFCSP, and its operating range is from - 40 ° C to+85 ° C.

PRODUCT HIGHLIGHTS

1. Fast Throughput

The AD7663 is a 250 kSPS charge redistribution, 16-bit

SAR ADC with various bipolar and unipolar input ranges.

2. Single-Supply Operation

The AD7663 operates from a single 5 V supply and dissipates

only 35 mW typical. Its power dissipation decreases with

the throughput to, for instance, only 15 µW at a 100 SPS

throughput.

It consumes 7 µW maximum when in power-down.

3. Superior INL

The AD7663 has a maximum integral nonlinearity of 3 LSB

with no missing 16-bit code.

4. Serial or Parallel Interface

Versatile parallel (8 bits or 16 bits) or 2-wire serial interface

arrangement compatible with both 3 V or 5 V logic.
