LTC1405CGN#PBF

LINEAR TECHNOLOGY  LTC1405CGN#PBF  模数转换器, 12 bit, 5 MSPS, 单, 4.75 V, 5.25 V, SSOP

The is a 12-bit sampling Analog-to-digital Converter ADC that draws only 115mW 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. It has a flexible input circuit that allows full-scale input ranges. The input common mode range is rail-to-rail and a common mode bias voltage 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.
