The LTC
1745 is a 25Msps, sampling 12-bit A/D con-
verter designed for digitizing high frequency, wide dy-
namic range signals. Pin selectable input ranges of
±1V
and
±1.6V along with a resistor programmable mode
allow the LTC1745’s input range to be optimized for a wide
variety of applications.
The LTC1745 is perfect for demanding communications
applications with AC performance that includes 72.5dB
SNR and 91dB spurious free dynamic range. Ultralow jitter
of 0.3psRMS allows undersampling with excellent noise
performance. DC specs include
±1LSB INL maximum and
±0.75LSB DNL over temperature.
The digital interface is compatible with 5V, 3V and 2V logic
systems. The ENC and ENC inputs may be driven differen-
tially from PECL, GTL and other low swing logic families or
from single-ended TTL or CMOS. The low noise, high gain
ENC and ENC inputs may also be driven by a sinusoidal
signal without degrading performance. A separate digital
output power supply can be operated from 0.5V to 5V,
making it easy to connect directly to low voltage DSPs
or FIFOs.
The TSSOP package with a flow-through pinout simplifies
the board layout.
