Overview

The AD7524 is an 8-bit monolithic CMOS multiplying digital-to-analog converter (DAC) designed for direct microprocessor interface. It features on-chip data latches and a thin-film R-2R ladder architecture. The device operates with supply voltages from +5 V to +15 V and consumes less than 10 mW typical power. Static performance includes relative accuracy ranging from ±1/2 LSB to ±1/8 LSB depending on the grade, with guaranteed monotonicity across the full temperature range. Dynamic settling time to 1/2 LSB is typically 250 ns at +15 V. Digital inputs are TTL/CMOS compatible, allowing seamless integration into bus-structured instruments and control systems.

Feature Summary

• On-chip data latches eliminate the need for external protection Schottky diodes.
• TTL and CMOS compatible inputs ensure compatibility with standard logic families.
• Multiplying capability supports 2- or 4-quadrant operation for gain and attenuation control.
• Guaranteed monotonicity across the entire operating temperature range.

Applications

• Microprocessor controlled gain circuits
• Microprocessor controlled attenuator circuits
• Precision automatic gain control (AGC) circuits
• Bus structured instruments

Procurement Notes

Verify the specific suffix code (e.g., JN, JR, SQ) to confirm the required package type and linearity grade. Military processing requires adding /883B to the part number. Confirm voltage and temperature specifications match the application requirements before ordering.

Selection Notes

Select the appropriate grade based on linearity needs: J/A/S for ±1/2 LSB, K/B/T for ±1/4 LSB, and L/C/U for ±1/8 LSB. Choose the package style (DIP, SOIC, PLCC, Cerdip, or LCCC) based on board space and mounting constraints. Ensure the supply voltage range (+5 V to +15 V) aligns with the system design.

Part Context

The AD7524 is part of the Analog Devices AD7524 series of 8-bit CMOS DACs. It serves as a buffered version of the standard AD7524, integrating input latches to simplify microprocessor interfacing. The component is widely used in applications requiring precise analog signal generation controlled by digital logic.

Replacement Considerations

Direct pin-compatible replacements include other grades within the AD7524 family (e.g., AD7524JN for AD7524KN). Verify that any substitute maintains the same resolution, output current characteristics, and latch functionality. Check if military variants require specific handling procedures.
