Low Power, 8-Bit, Dual 500 MSPS A/D Converter
General Description
The ADC08DL502 is a dual, low power, high performance,
CMOS analog-to-digital converter. The ADC08DL502 digi-
tizes signals to 8 bits of resolution at sample rates up to 500
MSPS. Consuming a typical 1.2 Watts in demultiplex mode at
500 MSPS from a single 1.9 Volt supply, this device is guar-
anteed to have no missing codes over the full operating
temperature range. The unique folding and interpolating ar-
chitecture, the fully differential comparator design, the inno-
vative design of the internal sample-and-hold amplifier and
the calibration schemes enable a very flat response of all dy-
namic parameters beyond Nyquist, producing a high 7.5
Effective Number of Bits (ENOB) with a 125 MHz input signal
and a 500 MHz sample rate while providing a 10^−18 Code
Error Rate (C.E.R.)
The converter typically consumes 3.3 mW in the Power Down
Mode and is available in a lead-free 144-lead LQFP and op-
erates over the modified Industrial (-40°C ≤ T_A ≤ +70°C)
temperature range.
