LTC1420 12-Bit, 10Msps,Sampling ADC
The LTC®1420 is a 10Msps, 12-bit sampling A/D converter that draws only 250mW from either single 5V or dual ±5V supplies. This easy-to-use device includes a high dynamic range sample-and-hold, a precision reference and a PGA input circuit. The LTC1420 has a flexible input circuit that allows full-scale input ranges of ±2.048V ±1.024V and ±0.512V. The input common mode voltage is arbitrary, though a 2.5V reference is provided for single supply applications. The input PGA has a digitally selectable 1x or 2x gain. Maximum DC specs include ±1LSB INL and ±1LSB DNL over temperature. Outstanding AC performance includes 71dB S/(N + D) and 83dB SFDR at the Nyquist input frequency of 5MHz. The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 100MHz bandwidth. The 75dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. A separate output logic supply allows direct connection to 3V components
