Overview

The AD7781BRZ is a 20-bit pin-programmable low power sigma-delta Analog-to-digital Converter (ADC) for bridge sensor products. Consuming only 330µA, the AD7781BRZ is particularly suitable for portable or battery-operated products where very low power is required. It also has a power-down mode that allows the user to switch-OFF the power to the bridge sensor and power down the AD7781BRZ when not converting, thus increasing the battery life of the product. For ease of use, all the features of the converter are controlled by dedicated pins. Each time a data read occurs, eight status bits are appended to the 24-bit conversion. These status bits contain a pattern sequence that can be used to confirm the validity of the serial transfer.
