Overview
The LTC2480IDD#TRPBF is a 16-bit, no-latency ΔΣ (Delta-Sigma) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device integrates 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 while maintaining exceptional DC accuracy.
