The AD7783 is a single-channel, 24-bit ADC with excitation current sources. It features pin-configurable input ranges, fixed update rate, simultaneous rejection of 50Hz and 60Hz, and more.
The AD7783 is a complete analog front-end designed for low-frequency measurement applications. It features a single-channel, 24-bit sigma-delta ADC that can be configured with gains of 1 or 16 to support full-scale input signal ranges of +2.56 V or +160 mV from a +2.5 V differential reference.
The device includes two integrated 200 pA current sources and operates in either master or slave mode via a simple, read-only digital interface with no on-chip registers to program. It is specified for single 3 V or 5 V operation and is available in a 16-lead TSSOP package.
