MAX520ACAP+T

Digital To Analog Converters Overview

The MAX520ACAP+T is a quad, 8-bit voltage-output digital-to-analog converter (DAC) featuring a simple 2-wire serial interface. It operates from a single +5V supply with reference inputs ranging from 0V to VDD. The device utilizes an R-2R architecture and provides unbuffered outputs that swing rail-to-rail. Key electrical parameters include a resolution of 8 bits, four channels, and a maximum serial clock frequency of 400kHz. Supply current is typically 16mA in operating mode and reduces to 4µA in power-down mode.

Digital To Analog Converters Feature Summary

• Quad 8-bit DACs with individual reference inputs for each channel
• I2C-compatible 2-wire serial interface supporting up to 400kbps data rates
• Ultra-low 4µA supply current in shutdown mode
• Power-on reset ensures outputs are at 0V upon initial power application

Digital To Analog Converters Applications

• Minimum component analog systems
• Digital offset and gain adjustment circuits
• Industrial process control instrumentation
• Automatic test equipment
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the specific package variant, as the MAX520 series includes DIP, SO, and SSOP options. Confirm RoHS compliance status for the specific suffix, as earlier versions may not meet current environmental standards. Check for obsolescence notices or lifecycle changes from Analog Devices/Maxim Integrated before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select the MAX520ACAP+T for applications requiring low pin count and minimal external components due to its integrated serial interface. Choose this part over buffered variants if lower supply current and higher accuracy at low output currents are prioritized over drive capability. Ensure the system supports I2C timing requirements for reliable communication.

Digital To Analog Converters Part Context

This component belongs to the MAX520/MAX521 family of quad and octal DACs manufactured by Analog Devices Inc./Maxim Integrated. The MAX520 specifically denotes the quad-channel version with unbuffered outputs, distinguishing it from the MAX521 which offers buffered outputs and eight channels. The ACAP+T suffix indicates the commercial temperature range and SSOP packaging.

Digital To Analog Converters Replacement Considerations

The MAX520ACAP+ is listed as a direct replacement for the non-RoHS MAX520ACAP. Verify functional compatibility regarding pinout and electrical characteristics when substituting older non-compliant parts with the '+' suffix versions.
