nel, simultaneous sampling 14-bit A/D converters designed
for digitizing high frequency, wide dynamic range signals.
AC performance includes 73.1dB SNR and 88dB spurious
free dynamic range (SFDR). Low power consumption per
channel reduces heat in high channel count applications.
Integrated bypass capacitance and flow-through pinout
reduces overall board space requirements.
DC specs include ±1LSB INL (typ), ±0.3LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 1.2LSB
RMS
.
The digital outputs are serial LVDS to minimize the num-
ber of data lines. Each channel outputs two bits at a time
(2-lane mode). At lower sampling rates there is a one bit
per channel option (1-lane mode).
The ENC
+
and ENC
–
inputs may be driven differentially
or single-ended with a sine wave, PECL, LVDS, TTL, or
CMOS inputs. An internal clock duty cycle stabilizer al-
lows high performance at full speed for a wide range of
clock duty cycles.
