GENERAL DESCRIPTION
The nAD1040-25 is a compact, high-speed, low power 10-bit monolithic analog-to-
digital converter, implemented in the TSMC Mixed-Signal MiM CMOS process. It
has 10-bit resolution with 9.5 effective bits, and close to 11 bit dynamic range for
video frequency signals. The converter includes a high bandwidth sample and hold.
The full scale range is
鹵1V.
The full scale range can be set between
鹵0.5V
and
鹵1V.
It operates from a single 2.5V supply. Its low distortion and high dynamic range offers
the performance needed for demanding imaging, multimedia, telecommunications and
instrumentation applications.
The bias current level for the ADC is automatically adjusted based on the clock input
frequency. Hence, the power dissipation of the device is continuously minimised for
the current operation frequency.
