Product Description

The AD7791BRMZ is a 1-channel 24-bit Ultra Low Power Sigma-Delta (Σ-Δ) Buffered ADC for low frequency measurement applications. It contains a low noise 24-bit Σ-Δ ADC with one differential input that can be buffered or unbuffered. The complete analogue front end device operates from an internal clock. Therefore, the user does not have to supply a clock source to the device. The output data rate from the part is software programmable and can be varied from 9.5Hz to 120Hz, with the RMS noise equal to 1.1µV at the lower update rate. The internal clock frequency can be divided by a factor of 2, 4 or 8, which leads to a reduction in the current consumption. The update rate, cut-off frequency and settling time will scale with the clock frequency. The part operates with a power supply from 2.5 to 5.25 V. When operating from a 3V supply, the power dissipation for the part is 225µW maximum.
1.1µV RMS noise at 9.5Hz update rate
19.5-bit p-p resolution (22-bit effective resolution)
3.5ppm Typical integral nonlinearity
Simultaneous 50 and 60Hz rejection
Internal clock oscillator
Rail-to-rail input buffer
ESD sensitive device, take proper precaution while handling the device.
