8 bit SAR ADC

Overview

The OT2101t180 is a low cost, low power, 8 bit single ended, SAR based, ADC core, with a 1Ms/S sample rate. It is designed for 1.8V operation with a typical 1.2V bandgap reference voltage.

Can be use used synchronous, or asynchronously with the available OT2912t zero pin oscillator.

Customized references and input buffers are available.

Designed for TSMC 0.18µ processes with MoM capacitors, or optionally MiM capacitors.

Multi-use licensing is $12K.
