General Description

Interleave Mode for 2x Sample Rate

The ADC08D1500 is a dual, low power, high performance

Multiple ADC Synchronization Capability

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 guaranteed to have no missing codes over the

full operating temperature range. The unique folding and in-

terpolating architecture, the fully differential comparator de-

sign, 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, produc-

ing a high 7.25 ENOB with a 748 MHz input signal and a 1.5

GHz sample rate while providing a 10^-18C.E.R. Output for-

matting 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.

Power Consumption

■

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.

Applications

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 LQFP and operates over the Indus-

trial (-40°C ≤ T_A≤ +85°C) temperature range.
