Part Details:

Low Power, 16-Bit Buffered Sigma-Delta ADC AD7790 FEATURES FUNCTIONAL BLOCK DIAGRAM Power GND V REFIN DD Supply: 2.5 V to 5.25 V operation Normal: 75 µA maximum VDD INTERNAL Power-down: 1 µA maximum CLOCK RMS noise: 1.1 µV at 9.5 Hz update rate 16-bit p-p resolution 16-BIT SERIAL AIN DIGITAL BUF ADC INTERFACE PGA Integral nonlinearity: 3.5 ppm typical Simultaneous 50 Hz and 60 Hz rejection AD7790 Internal clock oscillator GND Programmable gain amplifier 03538-0-001 Rail-to-rail input buffer Figure 1. VDD monitor channel Temperature range: ­40°C to +105°C GENERAL DESCRIPTION 10-lead MSOP The AD7790 is a low power, complete analog front end for INTERFACE low frequency measurement applications. It contains a low 3-wire serial noise 16-bit - ADC with one differential input that can be SPI®, QSPITM, MICROWIRETM, and DSP compatible buffered or unbuffered along with a digital PGA, which allows gains of 1, 2, 4, and 8. Schmitt trigger on SCLK The device operates from an internal clock. Therefore, the user APPLICATIONS does not have to supply a clock source to the device. The output Smart transmitters data rate from the part is software programmable and can be Battery applications varied from 9.5 Hz to 120 Hz, with the rms noise equal to
