AD7708BRUZ

The AD7708BRUZ from Analog Devices is a versatile 16-bit analog-to-digital converter (ADC) suitable for low-frequency measurement applications. It is part of the AD7708/AD7718 family, offering direct conversion of input signals ranging from 20 mV to 2.56 V without the need for external signal conditioning.

Key features include a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP systems. The device supports simultaneous 50 Hz and 60 Hz rejection, enhancing measurement accuracy in noisy environments. It operates from a single 3 V or 5 V supply, with typical current consumption of 1.28 mA at 3 V in normal mode and 30 µA in power-down mode.

Designed for applications such as industrial process control, instrumentation, pressure transducers, portable instrumentation, and smart transmitters, the AD7708BRUZ provides factory-calibrated performance. Its programmable gain front end and VREF Select™ capability allow for both absolute and ratiometric measurement configurations. The device can be optimized for analog performance or channel throughput based on the CHOP setting.

The AD7708BRUZ is available in a surface mount package. Its integrated functions include a rail-to-rail input buffer and PGA, along with a 2-bit digital I/O port.
