Overview
The LTC2484IDD#TRPBF, produced by Analog Devices Inc., is a 24-bit No Latency ΔΣ (Delta-Sigma) analog-to-digital converter (ADC) that incorporates patented Easy Drive technology. This ADC is designed to eliminate dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This feature allows for the direct digitization of input signals with large external source impedances and rail-to-rail input range, maintaining exceptional DC accuracy.
