Kit eases high-voltage designs

By Warren Webb -- EDN, 5/26/2005

Goal Semiconductor recently announced a plug-and-play development and evaluation system for their HVDAC200-4 quad, high voltage, 9-bit, serially configurable voltage/current D/A converter with outputs as high as 200V (Picture). The HVDAC 200 finds use in applications requiring high-voltage control, such as electrostatic MEMS (microelectromechanical-system) devices, test-and-measurement equipment, piezoelectric transducers, and high-voltage bias generation.

The development board features an 8051 microcontroller for communication with the PC-based demonstration software and to control the HVDAC 200, adjustable voltage/temperature parameters, terminal blocks for high-voltage I/O, and a prototyping area. The UVK-HVDAC200-4 development kit comes with the evaluation board, a sample HVDAC200-4, CD-based user guides, source code, a serial cable, and a power supply. The kit also includes an 8051 compiler and debugger to develop custom programs for high-voltage control. The UVK-HVDAC200-4 costs $250.
