The AD7783BRUZ is a read-only pin configured Analog-to-digital Converter (ADC) with excitation current sources for low frequency measurement applications. The 24-bit sigma-delta ADC contains one fully differential input channel that can be configured with a gain of 1 or 16 allowing full-scale input signal ranges of ±2.56V or ±160mV from a 2.5V differential reference input. It also contains two 200mA integrated current sources. It has an extremely simple, read-only digital interface that can be operated in master/slave mode. There are no on-chip registers to be programmed. The input signal range and current source selection are configured using two external pins. The device operates from a 32.768kHz crystal with an on-chip PLL generating the required internal operating frequency. The output data rate from the part is fixed via the master clock at 19.79Hz and provides simultaneous 50 and 60Hz rejection at this update rate. At this update rate, 18-bit p-p resolution can be obtained.
