LTC2498 - 24-Bit 8-/16-Channel ADC

General Description

The LTC®2498 is a 16-channel (8-differential) 24-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.
