Overview
The LTC2480CDD#PBF is a 16-bit, no-latency ΔΣ (Delta-Sigma) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is distinguished by its 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 large external source impedances and input signals with a rail-to-rail input range, maintaining exceptional DC accuracy.
