LTC2226H

12-Bit, 25Msps

125°C ADC in LQFP

DESCRIPTION

The LTC®2226H is a 12-bit 25Msps, low power 3V A/D

converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2226H is perfect for

demanding imaging and communications applications

with AC performance that includes 71.4dB SNR and 90dB

SFDR.

DC specs include ±0.3LSB INL (typ), ±0.3LSB 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.
