Overview
The LTC2482IDD#PBF is a 16-bit Delta-Sigma analog-to-digital converter (ADC) produced by Analog Devices Inc. This component integrates the patented Easy Drive technology, which eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows for the direct digitization of input signals with large external source impedances and rail-to-rail input range, maintaining exceptional DC accuracy.
