ADDAC85D-CBI-V

Digital To Analog Converters Overview

The ADDAC85D-CBI-V is a monolithic, low-cost 12-bit digital-to-analog converter manufactured by Analog Devices. It integrates a high-stability buried Zener reference and an output amplifier on a single chip. The device operates with binary complementary input (CBI) and supports voltage output modes with ranges including ±2.5 V, ±5 V, and ±10 V. It is specified for operation over the –25 °C to +85 °C temperature range. Key electrical parameters include a typical settling time of 4 µs to ±0.01% FSR for full-scale changes, a maximum linearity error of ±1/2 LSB at 25 °C, and a supply drain of 10 mA at +15 V and 20 mA at –15 V.

Digital To Analog Converters Feature Summary

• Monolithic construction with integrated precision buried Zener reference and output amplifier
• Guaranteed monotonicity over the –25 °C to +85 °C operating temperature range
• Low power dissipation of 300 mW with TTL-compatible digital inputs
• High stability SiCr thin film resistors laser trimmed for improved accuracy

Digital To Analog Converters Applications

• Industrial process control systems requiring reliable 12-bit conversion
• Data acquisition modules where cost and reliability are primary factors
• Replacement for standard DAC80 devices in existing designs
• Test and measurement equipment utilizing bipolar or unipolar voltage outputs

Digital To Analog Converters Procurement Notes

Verify that the component matches the monolithic technology specification for the ADDAC85 series. Confirm the package type corresponds to the D-24 outline as listed in the ordering guide. Ensure the input code configuration aligns with the Binary Complementary Input (CBI) requirement for this specific suffix.

Digital To Analog Converters Selection Notes

Select this model when an extended industrial temperature range of –25 °C to +85 °C is required compared to the standard ADDAC80N. Choose the CBI variant for direct compatibility with binary logic interfaces. Consider the hybrid versions if hermetic sealing is necessary for military or harsh environments, though those utilize different package codes.

Digital To Analog Converters Part Context

This part belongs to the ADDAC80/ADDAC85/ADDAC87 family of complete 12-bit D/A converters. The ADDAC85 designation specifically indicates the –25 °C to +85 °C temperature grade within the monolithic product line. It serves as an improved replacement for legacy DAC80 components, offering better performance through advanced circuit design and reduced power consumption.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes include the DAC80 and DAC800, which this device is designed to replace with significant performance increases.
