Description

The AD7610 is a 16-bit charge redistribution successive approximation register (SAR), architecture analog-to-digital converter (ADC) fabricated on Analog Devices, Inc.'siCMOS 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 onCNVSTsamples 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.ApplicationsProcess controlMedical instrumentsHigh speed data acquisitionDigital signal processingInstrumentationSpectrum analysisATE
