The LTC2228/LTC2227/LTC2226 are perfect for demanding imaging and communications applications with AC performance that includes 71.
3dB SNR and 90dB 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.
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.
