1 Introduction

Strides have been made over time to improve the accuracy and overall performance of Precision DACs while also providing higher resolutions. In the past, Precision DACs were DACs that performed at speeds less than or equal to 10 MSPS and focused on being highly accurate rather than speed. Due to this focus, precision DACs have been limited by resolution and have only seen superior linearity at around 16-bits.

Texas Instruments continues to invest in all of the digital-to-analog converter (DAC) markets, and recently released its first 20-bit, resistor-ladder based precision DAC, the DAC11001B. It features the highest precision, lowest noise, and lowest distortion at the highest update rate.

DAC11001B can be fit for numerous applications with the benefit of both static and dynamic performance. However, this application note reviews three leading applications that would benefit from the outstanding AC performance of this new DAC.

Also, it showcases how DAC11001B improves overall system-level performance.
