LTC2488
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.
Key Features
