This easy-to-use device includes a high dynamic range sample-and-hold and a programmable precision reference. The LTC1740 has a flexible input circuit that allows differential full-scale input ranges of ± 2.5V and ± 1.25V with the internal reference, or any full-scale input range up to ±2.5V with an external reference. The input common mode voltage is arbitrary, though a 2.5V reference is provided for single supply applications. DC specifications include 1LSB typical INL, 0.5LSB typical DNL and no missing codes over temperature. Outstanding AC performance includes 79dB S/(N␣ +␣ D) and 91dB SFDR at an input frequency of 2.5MHz. The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 80MHz bandwidth. The 75dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signa...
