The is a compact, high-speed, low power 10-bit monolithic analog-todigital converter, implemented a 0.18m 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 0.75V. The full scale range can be set between 0.5V and 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.

The nAD1020-18 has a pipelined architecture - resulting in low input capacitance. Digital error correction of the 9 most significant bits ensures good linearity for input frequencies approaching Nyquist. The nAD1020-18 is compact. The core occupies less than 0.9mm2 of die area in a standard single poly 0.18m CMOS process. The fully differential architecture makes it insensitive to substrate noise. Thus it is ideal as a mixed signal ASIC macro cell.
