MAX518AESA+T

Digital To Analog Converters Overview

The MAX518AESA+T is an 8-bit dual digital-to-analog converter with rail-to-rail buffered outputs. It operates from a single +5V supply, using VDD as the internal reference for both channels. The device features a 2-wire serial interface compatible with I2C, supporting data rates up to 400kbps. Key electrical parameters include a resolution of 8 bits, a maximum total unadjusted error of ±1.5 LSB, and a typical output settling time of 6µs. Supply current is 2.5mA in normal mode and reduces to 4µA in shutdown.

Digital To Analog Converters Feature Summary

• Dual 8-bit DACs with rail-to-rail voltage outputs
• Simple 2-wire serial interface with I2C compatibility
• Internal power-on reset ensures zero-code output at startup
• Low-power shutdown mode reduces supply current significantly

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to commercial variants. Confirm RoHS compliance status for the '+T' tape-and-reel packaging variant against current manufacturer certifications. Ensure the ordering code matches the required package type and thermal grade for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel DAC is required with minimal external components. The MAX518 uses the supply voltage as the reference, simplifying design compared to parts requiring external references. Choose this over the MAX517 if two independent channels are needed, or over the MAX519 if external reference inputs are not required for each channel.

Digital To Analog Converters Part Context

The MAX518 belongs to the MAX517/MAX518/MAX519 family of 8-bit voltage-output DACs manufactured by Analog Devices (Maxim Integrated). This series is characterized by its space-saving packages and simple serial communication protocol. The MAX518 specifically distinguishes itself within the family by providing two channels that share the supply voltage as their reference source.

Digital To Analog Converters Replacement Considerations

The MAX517 serves as a single-channel alternative within the same family. The MAX519 offers dual channels but requires external reference inputs for each DAC. When replacing, ensure the pinout compatibility between the 8-pin SOIC packages and verify that the system can accommodate the specific slave address configuration options available on these devices.
