AD7610

14位， 1 MSPS ，差分可编程输入的PulSAR ADC 14-Bit, 1 MSPS, Differential, Programmable Input PulSAR ADC

Product Details

The is a 16-bit charge redistribution successive approximation register SAR, architecture analog-to-digital converter ADC fabricated on Analog Devices, Inc."s _i_CMOS 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.
