AD557JPZ

AD557 is a DACPORT® complete voltage-output 8bit digital-to-analogue converter, including output amplifier, full microprocessor interface and precision voltage reference on a single monolithic chip. No external components or trims are required to interface, with full accuracy, an 8-bit data bus to an analogue system. The low cost and versatility of AD557 DACPORT are the result of continued development in 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. The internal precision voltage reference is the patented low-voltage band-gap circuit which permits full-accuracy performance on a single +5V power supply.
