GENERAL DESCRIPTION

Table 1. 48-Lead 14-/16-/18-Bit PulSAR Selection

The AD7610 is a 16-bit charge redistribution successive approxi-

mation register (SAR), architecture analog-to-digital converter

(ADC) fabricated on Analog Devices, Inc.’s iCMOS high voltage

process. The device is configured through hardware or via a

dedicated write only serial configuration port for input range

and operating mode. The AD7610 contains a high speed 16-bit

sampling ADC, an internal conversion clock, an internal reference

(and buffer), error correction circuits, and both serial and parallel
