The LTC
1750 is an 80Msps, 14-bit A/D converter de-
signed for digitizing wide dynamic range signals up to
frequencies of 500MHz. The input range of the ADC can be
optimized with the on-chip PGA sample-and-hold circuit
and flexible reference circuitry.
The LTC1750 has a highly linear sample-and-hold circuit
with a bandwidth of 500MHz. The SFDR is 82dB with an
input frequency of 250MHz. Ultralow jitter of 0.12psRMS
allows undersampling of IF frequencies with minimal
degradation in SNR. DC specs include
±3LSB INL and no
missing codes.
The digital interface is compatible with 5V, 3V, 2V and
LVDS logic systems. The ENC and ENC inputs may be
driven differentially 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 output power supply can be operated from 0.5V
to 5V, making it easy to connect directly to any low voltage
DSPs or FIFOs.
The 48-pin TSSOP package with a flow-through pinout
simplifies the board layout.
