Overview
The LTC2496IUHF#TRPBF is a 16-bit, 8-/16-channel ΔΣ (Delta-Sigma) Analog-to-Digital Converter (ADC) produced by Analog Devices Inc. This device features Analog Devices’ 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 rail-to-rail input signals with exceptional DC accuracy, even with large external source impedances.
The LTC2496 includes an integrated oscillator and can be configured to measure external signals from combinations of 16 analog input channels operating in single-ended or differential modes. It also automatically rejects line frequencies of 50Hz and 60Hz, enhancing its suitability for various applications.
