AH30217

The AH30217 is designed as one kind of 17-bit integrating A/D converter with high precision,high speed.It is an ultra-high-resolution 17-bit integrating A/D converter in a hybrid,40-pin,dual-in-line package.Performing up to 300 conversions per second,the AH30217 ensures accurate conversions by effectively eliminating internal drifts using a four-phase triple-slope integrating conversion scheme and an autozero before each conversion.The AH30217 features TTL-compatible data and control,making it easy to integrate into a system.Furthermore,the hybrid package minimizes the amount of valuable printed circuit board real eatate required to deliver this level of performance.

Features of the AH30217 are:(1)ultra-high resolution(17 bits);(2)high speed(300 conversions/second);(3)hybrid 40-pin DIP;(4)high input impedance(1000 M);(5)excellent differential linearity(+/-0.2 ppm FSR);(6)autozero before each conversion;(7)high absolute accuracy(+/-0.0025% FSR);(8)low input current(50 nA @ 100 conversions/second);(9)TTL compatibility;(10)low power(600 mW);(11)ratiometric measurements using external reference;(12)external system offset.

And the AH30217 can be used in (1)high resolution data acquisition and control systems;(2)precision chemical process control systems;(3)gas chromatography;(4)high resolution laboratory and R&D systems;(5)analytical instrumentation;(6)high precision automatic test equipment and (7)precision pharmaceutical mixing and grading systems.
