LTC2288 Dual 10-Bit, 65Msps Low Noise 3V ADC

The LTC®2288/LTC2287/LTC2286 are 10-bit 65Msps/ 40Msps/25Msps, low noise dual 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2288/LTC2287/LTC2286 are perfect for demanding imaging and communications applications with AC performance that includes 61.8dB SNR and 85dB SFDR for signals at the Nyquist frequency.

DC specs include ±0.1LSB INL (typ), ±0.05LSB DNL (typ) and ±0.6 LSB INL, ±0.5 LSB 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 3.6V logic. An optional multiplexer allows both channels to share one digital output bus.

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
