Product Summary

The AD7705BR is a 2-/3-channel, 16-bit, sigma-delta ADC. It can accept low level input signals directly from a transducer and produce serial digital output. The devices employ a conversion technique to realize up to 16 bits of no missing codes performance. The selected input signal is applied to a proprietary, programmable-gain front end based around an analog modulator.

Parametrics

AD7705BR absolue maximum rating (1)VDD to GND: -0.3 to 7V; (2)analog input voltage to GND: -0.3 to VDD+0.3V; (3)Reference input voltage to GND: -0.3 to VDD+0.3V; (4)Operating temperature range: -40 to 85℃; (5)junction temperature: 150℃.

Features

AD7705BR features: (1)2 fully differential input channel ADCs; (2)Programmable gain front end: gains from 1 to 128; (3)Power dissipation 1 mW maximum @ 3 V; (4)Standby current 8 μA maximum; (5)16-lead PDIP, 16-lead SOIC, and 16-lead TSSOP packages.
