Analog Devices AD558
The AD558 DACPORT® is a complete voltage-output 8-bit digital-to-analog converter, including output amplifier, full microprocessor interface and precision voltage reference on a single monolithic chip. The performance and versatility of the DACPORT is a result of several recently-developed monolithic bipolar technologies. The complete microprocessor interface and control logic is implemented with integrated injection logic (I2L), an extremely dense and low power logic structure that is process-compatible with linear bipolar fabrication.- Min Voltage : 4.5V
- Max Voltage : 16.5V
- Channels : 1
- Max Operating Temp : 125°C
- Min Operating Temp : -55°C

DESCRIPTION
PRODUCT HIGHLIGHTS No external components or trims are required to interface, with full accuracy, an 8-bit data bus to an analog system. The internal precision voltage reference is the patented low voltage bandgap circuit which permits fullaccuracy performance on a single +5 V to +15 V power supply.
