DAC

The single channel DAC16 module is a 16-bit Digital-to-Analog Converter module with a galvanically isolated serial interface. The module has been designed for maintenance, testing, integration and troubleshooting applications that require channel isolation and high accuracy. The module comes in two versions, one labeled DAC-16-20mA with a -20 mA current output, the other labeled DAC-16-12V with a 0 V - 12,75 V voltage output range.

Feature Highlights

The DAC16 features the following components and properties:

• 16-bit precision DAC IC
• I2C bus for sampling the current module temperature via the built-in LM 92 temperature sensor
• I2C EEPROM for writing module-specific data to memory (max. 2 kB) to be read and analyzed by an application
• Variable master clock supporting internal filtering
• 1 Watt thermal resistor for quickly obtaining operating temperature after power-on
• Heating is controlled either externally via pin #36 or internally via the programmable LM92 temperature sensor
• Serial interface (2 wire)
• Rugged metal case with a pin output layout according to the DIL 40 standard (reduced pin count)
