5962-9176402MXA

Overview

The DAC8412 is a quad, 12-bit voltage output digital-to-analog converter with readback capability. It features double-buffered inputs and resets to center scale upon activation of the active-low RESET pin. The device operates from supplies ranging from single +5 V to ±15 V. Electrical specifications at ±15 V include an integral nonlinearity error of ±0.5 LSB (E grade) or ±1 LSB (F grade), a settling time of 10 μs to 0.01%, and a large signal bandwidth of 160 kHz. Power dissipation is 330 mW with ±15 V supplies.

Feature Summary

• Quad 12-bit architecture with true buffered voltage outputs capable of sourcing/sinking 5 mA.
• Double-buffered digital inputs allowing simultaneous update of all channels via LDAC.
• Readback capability on the 12-bit data bus for verification of written codes.
• Active-low RESET function loads all output registers to midscale (Code 0x800).

Applications

• Automatic test equipment
• Digitally controlled calibration systems
• Servo controls
• Process control equipment

Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature range and package type. Standard commercial grades operate from -40°C to +85°C, while military grades (e.g., AT/BTC variants) support -55°C to +125°C. Confirm package availability, as the component is offered in 28-lead PDIP, PLCC, LCC, and CERDIP formats.

Selection Notes

Select the DAC8412 when a reset-to-center-scale state is required, distinguishing it from the DAC8413 which resets to zero scale. Ensure the reference voltage configuration supports the desired unipolar or bipolar output swing. Verify that the parallel interface timing requirements align with the system's bus access speed.

Part Context

This part number represents the commercial-grade version of the DAC8412. Analog Devices provides MIL-STD-883 qualified versions under standard military drawings, specifically ranging from 5962-9176401MXA through 5962-9176404M3A. These military variants extend the operating temperature range to -55°C to +125°C.

Replacement Considerations

The DAC8413 is functionally identical except for the reset state; it resets to minimum scale (zero code) rather than center scale. Other quad 12-bit DACs may require external buffering or lack the integrated readback feature.
