General Description

The LTC®2497 is a 16-channel (eight differential), 16-bit, No Latency DSTM ADC with Easy Drive technology and a 2-wire, I2C interface.

The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current.

This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy.
