MAX516ACWG

Overview

The MAX516ACWG is a dual, low-power, serially programmable digital-to-analog converter (DAC) featuring an on-chip precision reference and output amplifier. It operates from a single supply voltage ranging from 2.7V to 5.5V. The device accepts standard SPI-compatible serial data through a three-wire interface. It offers two independent voltage outputs with 8-bit resolution. The internal reference provides high accuracy, eliminating the need for external components in many applications.

Feature Summary

• Integrated precision voltage reference and output amplifiers reduce component count
• Serial interface compatible with standard SPI, QSPI, and MICROWIRE protocols
• Low power consumption suitable for battery-operated systems
• Single-supply operation simplifies system design

Applications

• Portable instrumentation
• Battery-powered measurement devices
• Programmable gain amplifiers
• Voltage level shifting circuits

Procurement Notes

Verify the specific suffix 'WG' indicates the TSSOP-14 package when ordering. Confirm the 'A' grade designation matches required temperature range specifications. Ensure the manufacturer source is Analog Devices Inc., as Maxim Integrated products are now part of ADI. Check for lead-free compliance markings on packaging documentation.

Selection Notes

Select this component when dual-channel DAC functionality is required with minimal external circuitry. Consider the 8-bit resolution limits for high-precision applications. Evaluate power supply constraints against the 2.7V to 5.5V operating range. Compare serial interface timing requirements with the host microcontroller capabilities before finalizing the design.

Part Context

This device belongs to the MAX516 family of dual DACs. It shares architectural similarities with other serial DACs but distinguishes itself through integrated reference and amp stages. The ACWG variant specifically denotes the commercial temperature range and thin-shrink small-outline package type within the broader product line.
