5962-87700032A

Overview

The AD7524 is an 8-bit monolithic CMOS digital-to-analog converter (DAC) designed for direct microprocessor interface. It integrates on-chip data latches and utilizes a thin-film R-2R ladder structure with N-channel current switches. 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, with guaranteed monotonicity across the full temperature range. Dynamic output settling time reaches 250 ns at +15 V. The architecture supports 2- or 4-quadrant multiplying applications without requiring external protection Schottky diodes.

Feature Summary

• Integrated on-chip data latches enable direct connection to microprocessor buses like 6800, 8085, and Z80.
• Guaranteed monotonicity over the full specified temperature range ensures stable control loop operation.
• Low power consumption with typical dissipation under 10 milliwatts during active operation.
• TTL/CMOS compatible inputs allow seamless interfacing with standard logic families using a +5 V supply.

Applications

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

Procurement Notes

Verify the specific suffix code against the ordering guide to confirm nonlinearity tolerance and package type. Military-grade variants require adding /883B to the part number and contacting sales for the dedicated datasheet. Confirm voltage supply requirements align with the selected grade's specifications for gain error and settling time.

Selection Notes

Select the J, K, or L suffix for commercial temperature ranges (-40°C to +85°C) or S, T, U for extended ranges (-55°C to +125°C). Choose higher letter grades (L, C, U) for tighter linearity accuracy of ±1/8 LSB. Ensure the package option matches the PCB layout constraints, as options include DIP, SOIC, PLCC, Cerdip, and LCCC.

Part Context

This part number corresponds to the Analog Devices AD7524 series, a widely used 8-bit multiplying DAC. The base model designation remains consistent across various temperature grades and packaging options, allowing designers to select environmental and physical form factors without changing the core functional specification.

Replacement Considerations

Direct substitutes within the same family include AD7524JN, AD7524KN, and AD7524LN for plastic DIP packages. For ceramic packages, consider AD7524SQ, AD7524TQ, or AD7524UQ. Verify pin compatibility and electrical parameters before substitution.
