SAN JOSE, Calif. – Feb. 15th , 2011 – Nuvoton Technology Corporation today announced the first device in its new line of high precision analog-to-digital converter (ADC) solutions– NAU780X. The NAU780X is a high-performance, cost-effective, low-power 24-bit sigma-delta ADC designed specifically for Weight Scales, Industrial Process Control, Strain Gauges, Data Acquisition, Portable Instrumentation and Fluid/Gas Analyzers. It delivers exceptional flexibility in performance and optimization of power consumption, while providing designers with development and test tools that can dramatically accelerate time to market. With the on-chip LDO and less external components, NAU780X can greatly reduce the BOM cost and PCB complexity.

The Nuvoton NAU780x is a precision low-power 24-bit ADC, with an onboard low-noise programmable gain amplifier (PGA), onboard RC or Crystal oscillator, and a precision 24-bit sigma-delta analog to digital converter (ADC) capable of up to 23-bit ENOB (Effective Number Of Bits) performance. This device provides a complete front-end solution for bridge/sensor measurement such as in weigh scales, strain gauges, and many other high resolution, low sample rate applications.

The many built-in features enable high performance applications with very low external parts count. NAU780X includes low drop-out regulator and high precision oscillator. Moreover, this device provides a standard 2-wire interface compatible with I2C protocol for simple and straightforward connection to and interoperation with a wide range of possible host processors. Also, NAU780X reserves hardware space for the on-chip calibration registers and algorithm so as to ease the software calculation burden and time.

The Programmable Gain Amplifier (PGA) provides selectable gains from 1 to 128, depending on the usage of different applications. The A/D conversion is performed with a Sigma-Delta modulator and programmable FIR filter that provides a simultaneous 50Hz and 60Hz notch filter to effectively improve interference immunity.

The NAU780X’s powerful development platform and simple graphical user interface development tools enable designers to efficiently generate new designs, giving them interactive programmability and predefined configuration paths for test and development and shorten the time to market.

In order to fulfill different customers’ need, NAU7801 8-pin solution is good at the minimal BOM cost. NAU7802 16-pin solution provides the superlative resolution for the accurate rated applications.

Availability, Pricing

The NAU7801 is available in an 8-SOP and an 8-DIP package. The packaged part is priced below US$1.25 in quantities of 1000.

The NAU7802 is available in a 16-SOP and a 16-DIP package. The packaged part is priced below US$1.50 in quantities of 1000.

Both NAU780X supports write capability via I2C, 2-Wire. Samples and evaluation boards are available today.
