LTC1420IGN#PBF

The LTC1420IGN#PBF is a 12-bit sampling Analog-to-digital Converter (ADC) 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. 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. 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.
