MAX521BCAG+T

Digital To Analog Converters Overview

The MAX521BCAG+T is an octal, 8-bit voltage-output digital-to-analog converter featuring a simple 2-wire serial interface. It operates from a single +5V supply and includes rail-to-rail output buffer amplifiers for reduced system size. The device supports data rates up to 400kbps and allows individual or simultaneous DAC register updates via double-buffered input configuration. It features a low-power shutdown mode reducing supply current to 4µA and ensures outputs are at 0V upon power-on reset.

Digital To Analog Converters Feature Summary

• Octal 8-bit resolution with rail-to-rail buffered outputs
• I2C-compatible 2-wire serial interface supporting up to 400kbps
• Ultra-low 4µA supply current in shutdown mode
• Power-on reset clears all latches to ensure zero-volt start

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 suffix 'G' against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing I2C bus protocols and check for any recent product change notices regarding the MAX521 series. Confirm that the + suffix indicates lead-free compliance if required by assembly standards.

Digital To Analog Converters Selection Notes

Select this component when an octal DAC configuration is required within a single package. The MAX521 variant is preferred over the MAX520 for applications needing buffered outputs to drive loads directly. Consider the 2-wire interface simplicity and the ability to address multiple devices on the same bus using AD0 and AD1 pins.

Digital To Analog Converters Part Context

This part belongs to the MAX520/MAX521 family of quad and octal 8-bit DACs manufactured by Analog Devices Inc./Maxim Integrated. The MAX521 specifically provides eight channels with buffered outputs, distinguishing it from the unbuffered MAX520. The family is designed for low-cost, space-constrained applications requiring multiple analog outputs controlled via standard serial protocols.

Digital To Analog Converters Replacement Considerations

Direct replacement options include other parts within the MAX521 series with different temperature grades or packaging, such as MAX521ACWG+ or MAX521BEPP+. Verify pinout compatibility and electrical characteristics before substitution.
