DESCRIPTION
The ADC083000 is a single, low power, high
performance CMOS analog-to-digital converter that
digitizes signals to 8 bits resolution at sampling rates
up to 3.4 GSPS. Consuming a typical 1.9 Watts at 3
GSPS from a single 1.9 Volt supply, this device is
specified to have no missing codes over the full
operating temperature range. The unique folding and
interpolating architecture, the fully differential
comparator design, the innovative design of the
internal sample-and-hold amplifier and the selfAPPLICATIONS
calibration scheme enable an excellent response of
all dynamic parameters up to Nyquist, producing a
high 7.0 Effective Number Of Bits, (ENOB) with a 748
MHz input signal and a 3 GHz sample rate while
providing a 10-18 Word Error Rate. The ADC083000
achieves a 3 GSPS sampling rate by utilizing both the rising and falling edge of a 1.5 GHz input clock.
Output formatting is offset binary and the LVDS
digital outputs are compatible with IEEE 1596.3-1996,
with the exception of an adjustable common mode
voltage between 0.8V and 1.15V.
The ADC has a 1:4 demultiplexer that feeds four
LVDS buses and reduces the output data rate on each bus to a quarter of the sampling rate.
The converter typically consumes less than 25 mW in
the Power Down Mode and is available in a 128-lead,
thermally enhanced exposed pad HLQFP and
operates over the Industrial (-40°C ≤ TA ≤ +85°C)
temperature range.
