Product Summary

The AD7720BRU is a 7th order sigma-delta modulator that converts the analog input signal into a high speed 1-bit data stream. It operates from a +5 V supply and accepts a differential input range of 0 V to +2.5 V or ±1.25 V centered about a common-mode bias. The AD7720BRU provides an accurate on-chip 2.5 V reference. A reference input/output function is provided to allow either the internal reference or an external system reference to be used as the reference source for the part. The AD7720BRU is offered in a 28-lead TSSOP package and designed to operate from –40℃ to +85℃.
