LTC2484IDD#PBF Description

The LTC2484IDD#PBF combines a 24-bit No Latency ∆Σ™ analog to-digital converterwithpatentedEasyDrive™ technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through the automatic cancellation of differential input current. This allows large external source impedances and input signals with rail-to-rail input range to be directly digitized while maintaining exceptional DC accuracy.
