GENERAL DESCRIPTION
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
system interface ports. A falling edge on CNVST 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
to 10 V, ±5 V, and ±10 V. Power consumption is scaled linearly
with throughput. The device is available in Pb-free 48-lead, low-
profile quad flat package (LQFP) and a lead frame chip-scale
(LFCSP_VQ) package. Operation is specified from −40°C to
+85°C.
