Overview
The LTC2497IUHF#TRPBF is a high-performance, 16-bit, 8-/16-channel delta-sigma analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is notable for its 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 LTC2497 includes an integrated oscillator and supports a 2-wire I2C interface. It can be configured to measure external signals from combinations of 16 analog input channels operating in single-ended or differential modes. The device also automatically rejects line frequencies of 50Hz and 60Hz simultaneously, enhancing its suitability for various applications.
