General Description

The LTC®2488 is a 4-channel (2-channel differential), 16‑bit, No Latency DS™ ADC with Easy Drive™ technology.

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-torail input signals to be directly digitized while maintaining exceptional DC accuracy.
