AD7789BRM Datasheet PDF - ADI

●Product Details

●The AD7788/AD7789 are low power, low noise, analog front ends for low frequency measurement applications. The AD7789 contains a low noise, 24-bit, ∑-∆ analog-to-digital converter (ADC) with one differential input. The AD7788 is a 16-bit version of the AD7789.

●The devices operate from an internal clock. Therefore, the user does not have to supply a clock source to the devices. The output data rate is 16.6 Hz, which gives simultaneous 50 Hz/60 Hz rejection.

●The devices operate with a single power supply from 2.5 V to 5.25 V. When operating from a 3 V supply, the power dissipation for the device is 225 µW maximum. The AD7788/AD7789 are available in a 10-lead MSOP.
