High Voltage, Quad, 9-bit V/I DAC Drives over 200V

Goal Semiconductor has launched the HVDAC 200, a high voltage, 4-channel, 9- bit, serially configurable voltage/current D/A converter. This employs an advanced highvoltage silicon process, making it capable of driving outputs in excess of 200V.

With an extremely high level of integration, the HVDAC 200 replaces in a single IC a plethora of peripheral analogue and digital circuitry, thus responding to market pressures for lower cost, reduce component count, and simplified design and production. It targets a broad range of applications requiring a programmable high voltage or current source, typically drivers or level translation for optical switching and control, projection systems, printers, transducers, and RF bias generation.

Based on a 9-bit current DAC, the HVDAC 200 can operate in either current or voltage mode. It delivers a maximum output voltage adjustable betwen 20V to 200V, and can be run in one of two maximum output current ranges: 500µA and 5mA. Each channel also includes over-current protection, and the HVDAC incorporates a temperature sensor that can effect shutdown in the event of overheating.

The HVDAC is controlled serially via an SPI interface. This includes a signal retransmission feature enabling users to daisy chain multiple devices, and a hardware reset that clears the internal registers.

Also available is a plug and play development and evaluation system, UVKHVDAC200- 4, which provides a complete and comprehensive platform for evaluation and prototype development.

It includes a Windows-based demonstration program that allows users to explore the full functional range of the HVDAC by connecting to a PC. The kit also includes an 8051-based development system with compiler/debugger, that can be used to develop custom programs for high voltage control.

A whole range of analogue and digital circuitry is eliminated by one chip.
