Goal Semiconductor Introduces a High Voltage, Quad, 9-bit Voltage/Current DAC

Montreal, (PRWEB) May 14, 2005

Goal Semiconductor today launched the HVDAC 200 – a high voltage, 4-channel, 9-bit, serially configurable voltage/current D/A converter. Using an advanced high voltage silicon process, the HVDAC is capable of driving outputs in excess of 200V.

 

The HVDAC targets a range of applications in the industrial, telecom, automotive, medical/scientific and consumer market segments that require high voltage control. These include drivers or level translation for optical switching and control, projection systems, printers, transducers, RF bias generation and other applications in which a programmable high voltage or current source is needed.

 

Technical description

 

The HVDAC is based on a 9-bit current DAC and can operate in either current or voltage mode. The output range of the DAC outputs is controlled by a low voltage reference input and each channel includes a 5-bit output offset adjustment. The maximum output range of the HVDAC can be adjusted from 20V to 200V.

 

The HVDAC can be run in one of two maximum output current ranges: 500µA and 5mA. An internal 600K Ohm resistor at the output of each channel can be used to set the output voltage range. The user can bypass this internal resistor and set the range via an external resistor as well. Each channel also includes over-current protection and the HVDAC incorporates a temperature sensor that can monitor device temperature and be used as a shutdown trigger in the case of overheating.

 

The HVDAC is controlled serially via an SPI interface that includes a signal retransmission feature so that users can daisy chain multiple devices. The device also includes a hardware reset that clears the internal registers.

 

Benefits of using the HVDAC 200

 

The HVDAC 200’s high level of integration makes it easy to replace circuitry that has traditionally required a plethora of discrete components made up of high voltage transistors, op amps, D/A converters and digital logic with a single IC. It, therefore, responds to the ever-increasing market pressure to lower costs, reduce component count and simplify design and production of electronic systems.
