FEATURES DESCRIPTION
n
Sample Rate: 25Msps
The LTC®2226H is a 12-bit 25Msps, low power 3V A/D n
–40°C to 125°C Operation
converter designed for digitizing high frequency, wide n
Single 3V Supply (2.8V to 3.5V)
dynamic range signals. The LTC2226H is perfect for n
Low Power: 75mW
demanding imaging and communications applications n
71.4dB SNR
with AC performance that includes 71.4dB SNR and 90dB n
90dB SFDR
SFDR. n No Missing Codes DC specs include ±0.3LSB INL (typ), ±0.3LSB DNL (typ) n Flexible Input: 1VP-P to 2VP-P Range and no missing codes over temperature. The transition n 575MHz Full Power Bandwidth S/H noise is a low 0.25LSB n RMS. Clock Duty Cycle Stabilizer n Shutdown and Nap Modes A single 3V supply allows low power operation. A separate n Pin Compatible Family output supply allows the outputs to drive 0.5V to 3.6V n LTC2246H (14-Bit), LTC2226H (12-Bit) logic. n 48-Pin (7mm × 7mm) LQFP Package A single-ended CLK input controls converter operation.
