General Description

D 52 Pin HTQFP Package With Exposed Heatsink D Pin Compatible to the AD6644/45 D Industrial Temperature Range = −405C to 855C APPLICATIONS D Single and Multichannel Digital Receivers D Base Station Infrastructure D Instrumentation D Video and Imaging RELATED DEVICES D Clocking: CDC7005 D Amplifiers: OPA695, THS4509 The ADS5423 is a 14 bit 80 MSPS analog-to-digital converter (ADC) that operates from a 5 V supply, while providing 3.3 V CMOS compatible digital outputs.

The ADS5423 input buffer isolates the internal switching of the on-chip Track and Hold (T&H) from disturbing the signal source.

An internal reference generator is also provided to further simplify the system design.
