DESCRIPTION
The ADC08D1500 is a dual, low power, high
performance CMOS analog-to-digital converter that
digitizes signals to 8 bits resolution at sample rates
up to 1.7 GSPS. Consuming a typical 1.8 Watts at
1.5 GSPS from a single 1.9 Volt supply, this device is
ensured 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 self-
calibration scheme enable a very flat response of all
dynamic parameters beyond Nyquist, producing a
high 7.25 ENOB with a 748 MHz input signal and a
1.5 GHz sample rate while providing a 10^-18 C.E.R.
Output formatting is 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 1.2V.
Each converter has a 1:2 demultiplexer that feeds
two LVDS buses and reduces the output data rate on
each bus to half the sample rate. The two converters
can be interleaved and used as a single 3 GSPS
ADC.
The converter typically consumes less than 3.5 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 ≤ T_A ≤ +85°C)
temperature range.
