5962-87700012A

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 R-2R ladder architecture with thin-film resistors. The device operates from +5 V to +15 V supplies, consuming less than 10 mW typical power. Static performance includes relative accuracy ranging from ±1/2 LSB to ±1/8 LSB depending on the grade. Dynamic settling time to 1/2 LSB is typically 250–500 ns. It supports TTL/CMOS inputs and guarantees monotonicity across the full temperature range.

Feature Summary

• 8-bit resolution with internal data latches for simplified bus interfacing
• Multiplying capability supporting 2- or 4-quadrant operation
• TTL and CMOS compatible digital inputs without external protection Schottky diodes
• Monotonicity guaranteed over the entire operating temperature range

Applications

• Microprocessor controlled gain circuits
• Microprocessor controlled attenuator circuits
• Precision automatic gain control (AGC) systems
• Bus structured instruments requiring function generation

Procurement Notes

Verify the specific suffix code (e.g., JN, JR, SQ) to confirm the package type and temperature range. Military processing requires adding /883B to the part number. Confirm RoHS compliance status as older revisions may not meet current environmental standards. Check datasheet revision B for updated electrical specifications before finalizing procurement.

Selection Notes

Select the grade based on required linearity: J/A/S versions offer ±1/2 LSB, K/B/T offer ±1/4 LSB, and L/C/U offer ±1/8 LSB. Choose packages such as N-16 (Plastic DIP), R-16A (SOIC), or Q-16 (Cerdip) based on board space and mounting requirements. Ensure supply voltages align with the +5 V to +15 V operational limits specified in the static performance table.

Part Context

This component belongs to the Analog Devices AD7524 series of low-cost, high-speed DACs. It is a CMOS version of earlier bipolar DACs, offering lower power consumption and direct microprocessor compatibility. The device serves as a foundational building block for analog signal generation and control in embedded systems.

Replacement Considerations

Direct pin-compatible replacements within the same family include AD7524JN, AD7524JR, and AD7524SQ, differing primarily in accuracy grades and temperature ranges. Cross-family replacements require verification of pinout compatibility and electrical parameter alignment.
