Description

The LTC®2293/LTC2292/LTC2291 are 12-bit 65Msps/ 40Msps/25Msps, low power dual 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2293/LTC2292/LTC2291 are perfect for demanding imaging and communications applications with AC performance that includes 71dB SNR and 85dB 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 3.3V logic. An optional multiplexer allows both channels to share a digital output bus.

A single-ended CLK input of LTC2293/LTC2292/LTC2291  controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
