LTC2291 - Dual 12-Bit, 25Msps Low Power 3V ADCs _ BDTIC a Leading Distributor in China

LTC2291 - Dual 12-Bit, 25Msps Low Power 3V ADCs

DC specs include ±0.3LSB INL (typ), ±0.15LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.25LSBRMS.

A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic. An optional multiplexer allows both channels to share a digital output bus.

A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
