Product Summary

The AD7708BRZ is a low voltage ADC for low frequency measurement applications. Input signal ranges from 20 mV to 2.56 V can be directly converted using these ADC. Signals can be converted directly from a transducer without the need for signal conditioning. The AD7708BRZ operates from a 32 kHz crystal with an on-board PLL generating the required internal operating frequency. The applications of the AD7708BRZ are Industrial Process Control, Instrumentation, Pressure Transducers, Portable Instrumentation, Smart Transmitters.
