5962-8770003EA

Overview

The AD7524 is an 8-bit monolithic CMOS digital-to-analog converter (DAC) designed for direct microprocessor interface. It features on-chip data latches and TTL/CMOS compatible inputs, eliminating the need for external protection Schottky diodes. The device utilizes a thin-film R-2R ladder structure with N-channel current switches to provide multiplying characteristics suitable for 2- or 4-quadrant operation. Key electrical parameters include a typical power dissipation of less than 10 mW, output current settling time of 400 ns max at +5 V supply, and relative accuracy ranging from ±1/2 LSB to ±1/8 LSB depending on the grade. Monotonicity is guaranteed across the full temperature range.

Feature Summary

• Integrated on-chip data latches allow direct connection to most microprocessor buses without external latch components.
• TTL and CMOS compatible inputs ensure interoperability with standard logic families when using a +5 V supply.
• Monotonicity is guaranteed over the entire specified temperature range for all available grades.
• Low power consumption with typical dissipation under 10 milliwatts during operation.

Applications

• Microprocessor controlled gain circuits
• Microprocessor controlled attenuator circuits
• Precision automatic gain control (AGC) systems
• Bus structured instruments requiring digital signal adjustment

Procurement Notes

Verify the specific suffix code against the ordering guide to confirm temperature range and linearity grade. Military processing requires adding /883B to the part number. Confirm package type matches the application requirements, as options include DIP, SOIC, PLCC, Cerdip, and LCCC. Ensure voltage supplies align with the absolute maximum ratings to prevent damage.

Selection Notes

Select the grade based on required relative accuracy: J/A/S versions offer ±1/2 LSB, K/B/T versions provide ±1/4 LSB, and L/C/U versions deliver ±1/8 LSB. Choose the temperature range according to environmental conditions: commercial/industrial (-40°C to +85°C) or extended (-55°C to +125°C). Verify that the chosen package fits the PCB layout constraints, noting differences between narrow DIP, SOIC, and leadless carriers.

Part Context

The 5962-8770003EA designation refers to a military-standard version of the AD7524 DAC processed under MIL-STD-883, Class B. This part corresponds to the commercial AD7524 family but adheres to stricter screening and reliability standards defined by the U.S. Standard Military Drawing (SMD) DESC #5962-87700. It retains the same functional specifications as the commercial counterpart while meeting defense industry quality requirements.

Replacement Considerations

Direct pin-compatible replacements within the AD7524 family include variants with different accuracy grades (e.g., AD7524JN vs AD7524LN) or packages. For military applications, verify if the /883B suffix is required. No other manufacturer part numbers are explicitly listed as substitutes in the provided documentation.
