general Description
the HMCAD1041-80 is a high performance ultra
low power analog-to-digital converter (ADC). the
ADC employs internal reference circuitry, a CMos
control interface, CMos output data and is based
on a proprietary structure. Digital error correction is
employed to ensure no missing codes in the complete
full scale range.
two idle modes with fast startup times exist. the entire
chip can either be put in standby Mode or Power
Down mode. the two modes are optimized to allow
the user to select the mode resulting in the lowest
possible energy consumption during idle mode and
startup.
the HMCAD1041-80 has a highly linear tHA optim-
ized for frequencies up to nyquist. the differential
clock interface is optimized for low jitter clock sources
and supports LvDs, LvPeCL, sine wave and CMos
clock inputs.
Pin compatible with HMCAD1041-40, HMCAD1051-40
and HMCAD1051-80.
