Description

The ADC081000 is a low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at sampling rates up to 1.6 GSPS while consuming a typical 1.4 Watts from a single 1.9 Volt supply at 1.0 GSPS. This device is guaranteed to have no missing codes over the full operating temperature range. The unique folding/interpolating architecture, the fully differential comparator design and the innovative design of the internal
sample-and-hold amplifier enable a very flat SINAD/ENOB response beyond Nyquist, producing a high 7.5 ENOB with a 100 MHz input signal and a 1 GHz sample rate. Output formatting is offset binary coding with LVDS digital outputs compliant with IEEE 1596.3-1996, with the exception of a reduced common mode voltage of 0.8V.

The ADC081000 converter has a 1:2 demultiplexer that feeds two LVDS buses and reduces the output data rate on each bus to half the sampling rate. The data on these buses are interleaved in time to provide a 500 MSPS output rate per bus and a combined output rate of 1 GSPS. Setting the PD (Power Down) pin high places the converter into an inactive power down state, where it typically consumes less than 5 mW. The ADC081000 is available in a 128-lead exposed pad LQFP and operates over the industrial (-40^oC TA +85^oC) temperature range.
