∆Σ™ analog-to-digital converter with patented Easy Drive™
technology. The patented sampling scheme eliminates
dynamic input current errors and the shortcomings of onchip buffering through automatic cancellation of differential
input current. This allows large external source impedances
and input signals, with rail-to-rail input range to be directly
digitized while maintaining exceptional DC accuracy. n APPLICATIONS Direct Sensor Digitizer Weight Scales …
