LTC2246H 14-Bit, 25Msps 125°C ADC In LQFP
FEATURES DESCRIPTION
n
Sample Rate: 25Msps
The LTC®2246H is a 14-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 LTC2246H is perfect for n
Low Power: 75mW
demanding imaging and communications applications n
74.5dB SNR
with AC performance that includes 74.5dB SNR and 90dB n
90dB SFDR
SFDR. n No Missing Codes DC specs include ±1LSB INL (typ), ±0.5LSB 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 1LSBRMS. n 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 LTC2246H (14-Bit), LTC2226H (12-Bit) logic. n 48-Pin (7mm × 7mm) LQFP Package A single-ended CLK input controls converter operation.
