LTC2492CDE#PBF developed by Linear Technology/Analog Devices belongs to the family of 4-channel (2-channel differential), 24-bit, No Latency ∆∑™ ADC with Easy Drive technology allowing for input current cancellation. With the patented sampling scheme, dynamic input current errors can be eliminated and the shortcomings of on-chip buffering through automatic cancellation of differential input current can be avoided. As a result, large external source impedances and rail-to-rail input signals can be allowed to be directly digitized while maintaining exceptional DC accuracy.
