ADDAC87CBI-V

Digital To Analog Converters Overview

The ADDAC87CBI-V is a monolithic 12-bit digital-to-analog converter featuring an integrated high-stability buried Zener reference and output amplifier. It operates within a temperature range of -55°C to +125°C and accepts parallel binary input codes. The device provides voltage outputs with selectable ranges including ±2.5 V, ±5 V, ±10 V, and +5 V. Key electrical parameters include a maximum linearity error of ±1/2 LSB at 25°C, a typical settling time of 3 µs for full-scale transitions, and a supply drain of 10 mA on the positive rail and 20 mA on the negative rail.

Digital To Analog Converters Feature Summary

• Monolithic construction with integrated precision buried Zener reference and output amplifier
• Guaranteed monotonicity over the specified -55°C to +125°C temperature range
• Parallel binary input interface compatible with TTL logic levels
• Laser-trimmed SiCr thin-film resistors for low differential nonlinearity

Digital To Analog Converters Applications

• High-reliability data acquisition systems requiring wide temperature operation
• Industrial process control loops utilizing bipolar offset configurations
• Test and measurement equipment demanding low power dissipation (300 mW)
• Replacement for standard DAC80 devices in existing designs

Digital To Analog Converters Procurement Notes

Verify that the specific unit matches the monolithic technology variant rather than the hybrid version, as specifications differ between technologies. Confirm the package type corresponds to the DH-24A outline for the CBI-V designation. Ensure power supply decoupling capacitors are placed close to the device pins to maintain performance stability.

Digital To Analog Converters Selection Notes

Select this model when extended temperature coverage (-55°C to +125°C) is required alongside low cost and single-chip simplicity. Choose the CBI-V suffix for parallel binary input compatibility and voltage output mode. Verify that the application can accommodate the ±15 V rated analog supplies and the specific settling time requirements associated with the monolithic architecture.

Digital To Analog Converters Part Context

The ADDAC87 is part of the ADDAC80 series family, which also includes the ADDAC80 and ADDAC85 models. While the ADDAC80 covers 0°C to +70°C and the ADDAC85 covers -25°C to +85°C, the ADDAC87 extends the operational range to -55°C to +125°C. All three share similar functional block diagrams but differ in temperature specifications and internal component trimming.

Digital To Analog Converters Replacement Considerations

The datasheet identifies the ADDAC80 series as an improved replacement for standard DAC80 and Hl-5680 devices. Designers upgrading from these legacy components should verify that the new settling times and power supply requirements align with the existing system constraints.
