LTC2247 - 14-Bit, 40Msps Low Power 3V ADC - Linear Technology（凌力尔特）

功能描述

The LTC2248/LTC2247/LTC2246 are 14-bit 65Msps/40Msps/25Msps, low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2248/LTC2247/LTC2246 are perfect for demanding imaging and communications applications with AC performance that includes 74dB SNR and 80dB SFDR for signals well beyond the Nyquist frequency.

DC specs include ±1LSB INL (typ), ±0.5LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 1LSBRMS.

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.
