Microchip Delta - Sigma A/D

Delta - Sigma A/D

Offering superior noise immunity and 16- to 24-bit resolution, our high-resolution, lower-power delta-sigma Analog-to-Digital Converters (ADCs) are well suited for use in for high-precision industrial applications, such as precision measurement, sensor signal conditioning, power monitoring and battery management. Other features, like voltage reference and Programmable Gain Amplifier (PGA), can cut the number of external components needed in your system design to reduce its complexity and costs.

Highlights

High resolution and lower noise for a variety of precision applications

Low power consumption for the given speed extends battery life in portable applications

Small package options, such as SOT-23 or 2 × 3 mm DFN packages, are ideal for space-constrained designs

Integrated features can simplify design and optimize total system cost
