CM2211bg – 2nd order ∆Σ ADC 12 bits 20kSPS speed

Data Converters

This macro-cell is a general purpose, 80dB/20kSPS Delta-Sigma (ΣΔ)Analog-to-Digital Converter (ADC) core designed for LFoundry 0.15μm LF150 CMOS technology STD (Standard) and LP (Low Power) process.

The circuit is optimized for sensor interfaces, enabling multiple system utilizations in applications like energy meter and instrumentation.

The 2nd order modulator operates with a 250 Oversampling Rate (OSR) and uses one 3.3V analog and one 1.8V digital supplies. The core is easily retargeted to any other CMOS technology.
