GENERAL DESCRIPTION
The nAD1040-18 is a compact, high-speed, low power 10-bit monolithic analog-to-
digital converter, implemented in a 0.18碌m single poly CMOS process with MiM
capacitor option. The converter includes a high bandwidth sample and hold. Using
internal references, the full scale range is
鹵0.75V.
The full scale range can be set
between
鹵0.5V
and
鹵0.75V
using external references. It operates from a single 1.8V
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.
