GENERAL DESCRIPTION
The nAD1260-25 is a compact, high-speed, low power 12-bit monolithic analog-to-
digital converter, implemented in the TSMC Mixed-Signal MiM CMOS process. It
has 12-bit resolution with more than 10 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 ±1V. The full scale range can be set between ±0.5V
and ±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.
