The LTC2293/LTC2292/LTC2291 are perfect for demanding imaging and munications applications with AC performance that includes 71.3d B SNR and 90d B SFDR for signals at 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. An optional multiplexer allows both channels to share a 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
