The AD7709BRUZ is a complete analog front end sigma-delta Analog-to-digital Converter (ADC) with switchable current sources. It is suitable for use with the low frequency measurement applications. It contains a 16-bit ADC, selectable reference inputs, three switchable matched excitation current sources, low-side power switches and a digital I/O port. The 16-bit channel with PGA accepts fully differential, uni-polar and bipolar input signal ranges from 1.024 REFIN/128 to 1.024 REFIN. It can be configured as two fully differential input channels or four pseudo-differential input channels. Signals can be converted directly from a transducer without the need for signal conditioning. 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 software programmable. The p-p resolution from the part varies with the programmed gain and output data rate.

• Programmable gain front end
• VREF Select? Allows absolute and ratiometric measurement capability
• 3-wire serial SPI?/QSPI?/MICROWIRE?/DSP compatible Schmitt trigger on SCLK
• Rail-to-rail input buffer and PGA
• Low-side power switches
