LTC2225 - 12-Bit, 10Msps Low Power 3V ADC - Linear Technology（凌力尔特）

功能描述

The LTC2225 is a 12-bit 10Msps, low power 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2225 is perfect for demanding imaging and communications applications with AC performance that includes 71.3dB SNR and 90dB SFDR for signals well beyond the Nyquist frequency.

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.

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.
