ADC082500
High Performance, Low Power, 8-Bit, 2.5 GSPS A/D
Converter
General Description
Note: This product is currently in development. - ALL
specifications are design targets and are subject to
change.
The ADC082500 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 1.8 Watts at 2.5 GSPS from a single 1.9 Volt supply,
this device is guaranteed 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 up to Nyquist, pro-
ducing a high 7.0 ENOB with a 748 MHz input Signal. A 2.5
GHz sample rate will provide a 10
-18 B.E.R. The ADC082500
achieves a 2.5GSPS sampling rate by utilizing both the
rising and falling edge of a 1.25 GSPS input clock. Output
formatting is offset binary and the LVDS digital outputs are
compliant with IEEE 1596.3-1996, with the exception of an
adjustable common mode voltage between 0.8V and 1.2V.
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 ADC can be programmed
into the 1:2 Output Mode where the data is output on the Dc
and Dd channels at the rate of the input clock.
The converter typically consumes less than 20 mW in the
Power Down Mode and is available in a 128-lead, thermally
enhanced exposed pad LQFP and operates over the Indus-
trial (-40˚C
≤ T
A
≤ +85˚C) temperature range.
