LTC2281 - Dual 10-Bit, 125Msps Low Power 3V ADC _ BDTIC a Leading Distributor in China

LTC2281 - Dual 10-Bit, 125Msps Low Power 3V ADC

Typical DC specs include ±0.1LSB INL, ±0.1LSB DNL. The transition noise is a low 0.08LSBRMS.

A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic.

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. A data ready output clock (CLKOUT) can be used to latch the output data.
