LTC2246H
14-Bit, 25Msps
125°C ADC In LQFP
DESCRIPTION
The LTC^®2246H is a 14-bit 25Msps, low power 3V A/D
converter designed for digitizing high frequency, wide
dynamic range signals. The LTC2246H is perfect for
demanding imaging and communications applications
with AC performance that includes 74.5dB SNR and 90dB
SFDR.
DC specs include ±1LSB INL (typ), ±0.5LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 1LSB_RMS.
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.
