16-Bit Sigma Delta ADC With Current Sources, Switchable Reference Inputs And I/O Port

The AD7709 is a complete Analog front-end for low frequency measurement applications. The AD7709 contains a 16-bit sigma delta ADC with PGA and CAN be configured as 2 fully-differential input channels or 4 pseudo-differential input channels. Inputs signal ranges from 20mV to 2.56V CAN be directly converted using the AD7709. These signals CAN be converted directly from a transducer without the need for Signal Conditioning Other on-chip features include three software configurable current sources, switchable reference inputs, low side Power Switches and a 4-bit digital I/O port.
