TIPD149 Reference Design

Texas Instruments

Power-optimized 16-bit 1MSPS Data Acquisition Block for Lowest Distortion and Noise Reference Design

Description

This TI Verified Design is the realization of a high precision: 16-bit 1MSPS data acquisition system suitable for applications such as digital audio that require front-ends with very low distortion and noise. The circuit uses a high performance Successive Approximation Register Analog to Digital Converter (SAR ADC) and has been optimized to provide superior dynamic performance: without excessive power consumption.
