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  
100 kSPS to

samples the  
analog input on IN+ with respect to a ground sense, IN−. The  
AD7610 features four different analog input ranges: 0 V to 5 V, 0 V

profile quad flat package (LQFP) and a lead frame chip-scale  
(LFCSP_VQ) package. Operation is specified from −40°C to  
+85°C.
