14-Bit, 65Msps ADC
The LTC
2205-14 is a sampling 14-bit A/D converter de-
signed for digitizing high frequency, wide dynamic range
signals up to input frequencies of 700MHz. The input range
of the ADC can be optimized with the PGA front end.
The LTC2205-14 is perfect for demanding communications
applications, with AC performance that includes 78.3dB
SNR and 98dB spurious free dynamic range (SFDR).
Ultralow jitter of 90fs
RMS
allows undersampling of high
input frequencies with excellent noise performance.
Maximum DC specs include ±1.5LSB INL, ±1LSB DNL
(no missing codes).
A separate output power supply allows the CMOS output
swing to range from 0.5V to 3.6V.
The ENC
+
and ENC
–
inputs may be driven differentially
or single-ended with a sine wave, PECL, LVDS, TTL or
CMOS inputs. An optional clock duty cycle stabilizer al-
lows high performance at full speed with a wide range of
clock duty cycles.
