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. The device operates from a 32kHz crystal with an onboard PLL generating the required internal operating frequency. The output data rate from the part is software programmable. The pk-pk resolution from the part varies with the programmed gain and output data rate. The part operates from a single +3V or +5V supply. When operating from +3V supplies, the power dissipation for the part is XmW. The AD7709 are housed in a 24pin SOIC and TSSOP packages.
