MAX526DENG

Digital To Analog Converters Overview

The MAX526DENG is a calibrated, quad, 12-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an R-2R architecture with four independent converters housed in a 24-pin PDIP package. The device operates on dual power supplies ranging from -5V to +12V or +15V for both analog and digital domains. Key electrical specifications include a typical settling time of 3 microseconds, a maximum differential nonlinearity (DNL) of ±1 LSB, and a maximum integral nonlinearity (INL) of ±0.5 LSB. It draws 11 mA of operating current and dissipates up to 733 mW of power. The component supports parallel data interfaces and buffered voltage outputs, functioning within a commercial temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Programmable gain amplifier circuits
• Waveform generation applications
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'D' indicates the commercial temperature grade (0°C to +70°C) distinct from industrial variants. Confirm the 'E' suffix denotes the PDIP-24 through-hole package. Check manufacturer documentation for end-of-life status, as older Maxim parts may have limited availability or require obsolescence management strategies.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC with high DC accuracy and parallel interface is required. Ensure the design accommodates dual supply voltages (-5V and +12V/+15V). Verify that the 12-bit resolution and ±0.5 LSB INL meet system precision requirements. Consider the PDIP package size if PCB real estate allows for through-hole mounting.

Digital To Analog Converters Part Context

The MAX526 belongs to the Maxim Integrated family of calibrated quad 12-bit DACs. It serves as a legacy solution for applications needing multiple synchronized analog outputs. The part number structure typically follows the pattern MAX526[Grade][Package][Suffix], where the grade determines temperature range and the package defines the physical form factor.
