The AD7782BRUZ is a 24-bit sigma-delta analog-to-digital converter (ADC) from Analog Devices designed for low-frequency measurement applications. It features two fully differential input channels with pin-programmable input ranges of ±2.56V or ±160mV, achieved via an on-chip programmable gain amplifier (PGA). The ADC operates at a fixed 19.79 Hz update rate and provides simultaneous 50 Hz and 60 Hz rejection, making it suitable for noisy industrial environments.
The AD7782 has a simple, read-only digital interface that supports SPI, QSPI, MICROWIRE, and DSP-compatible protocols. It can operate in master or slave mode and includes a Schmitt trigger on the SCLK input. The device requires an external voltage reference and can be powered from a single 3V or 5V supply. In normal operation at 3V, it draws 1.3 mA; a power-down mode reduces current to 9 µA.
The ADC is available in a 16-lead TSSOP surface-mount package and operates over the industrial temperature range of -40°C to +85°C. The peak-to-peak resolution is 18.5 bits on the ±2.56V range and 16.5 bits on the ±160mV range. The architecture is sigma-delta with a MUX-PGA-ADC configuration, ensuring high-resolution conversion without missing codes.
The AD7782BRUZ operates from a 3V supply (2.7V to 3.6V) or a 5V supply.
It is available in a 16-TSSOP (0.173", 4.40mm Width) surface mount package.
