Low Power 3V ADCs

The LTC

®2293/LTC2292/LTC2291 are 12-bit 65Msps/

40Msps/25Msps, low power dual 3V A/D converters de-

signed 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 controls converter operation. An

optional clock duty cycle stabilizer allows high perfor-

mance at full speed for a wide range of clock duty cycles.
