5. Description
The AT84AS001 is a high-performance 12-bit 500 Msps ADC featuring low-power consumption and true
12-bit linearity for IF sampling applications. By using its on-chip S/H circuitry and advanced high-speed
process technology, it allows conversion of wide-bandwidth signals up to 500 MHz of input frequency at
500 Msps. Its electrical performance is coupled with ease of integration into new or existing designs by
such features as AC or DC coupled analog input, differential LVDS compatible output, 3-wire serial inter-
face (gain and offset control, standby mode, Built-In Test), double data rate clock output and
synchronous reset input.

Note:
Absolute maximum ratings are limiting values (referenced to GND = 0V), to be applied individually, while other parameters are
within specified operating conditions. Long exposure to maximum rating might affect device reliability. All integrated circuits have
to be handled with appropriate care to avoid damages due to ESD. Damage caused by inappropriate handling or storage could
range from performance degradation to complete failure.
