功能描述

The LTC2238/LTC2237/LTC2236 are 10-bit 65Msps/40Msps/25Msps, low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2238/LTC2237/LTC2236 are perfect for demanding imaging and communications applications with AC performance that includes 61.6dB SNR and 80dB SFDR for signals well beyond the Nyquist frequency.

DC specs include ±0.1LSB INL (typ), ±0.05LSB DNL (typ) and ±0.5LSB INL, ±0.5LSB DNL over temperature. The transition noise is a low 0.07LSBRMS.

A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.3V 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.
