Overview
The LTC2488CDE#TRPBF is a high-precision, 16-bit, delta-sigma analog-to-digital converter (ADC) produced by Analog Devices Inc. This device features 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 rail-to-rail input signals while maintaining exceptional DC accuracy. The LTC2488 includes an integrated oscillator and can be configured to measure external signals from combinations of four analog input channels operating in single-ended or differential modes. It also automatically rejects line frequencies of 50Hz and 60Hz simultaneously.
