The LTC®2496 is a 16-channel (8-differential) 16-bit No Latency ΔΣ™ 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-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy.
