MAX513ESD+

Digital To Analog Converters Overview

The MAX513ESD+ is a triple, 8-bit voltage-output digital-to-analog converter featuring a 3-wire serial interface compatible with SPI, QSPI, and Microwire. It operates from a single +2.7V to +3.6V supply or split supplies. The device includes two buffered outputs (DAC A/B) and one unbuffered output (DAC C). DAC A provides 5mA drive capability, while DAC B supports 0.5mA. Supply current is 1mA, dropping below 1µA in shutdown.

Digital To Analog Converters Feature Summary

• Triple 8-bit DAC architecture with independent control
• Buffered outputs for DAC A and DAC B with rail-to-rail swing
• Unbuffered DAC C for high-accuracy applications
• Independent programmable shutdown mode per channel

Digital To Analog Converters Applications

• Digital gain and offset adjustment
• Programmable attenuators
• RF digitally adjustable bias circuits
• VCO tuning
• Programmable voltage sources

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ESD+' against the manufacturer's current product status, as older Maxim Integrated parts may have limited availability or obsolescence risks. Confirm that the SOIC-14 package matches the design footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the system environment specifications before finalizing procurement.

Digital To Analog Converters Selection Notes

Select the MAX513 variant specifically for +3V to +3.6V single-supply operation; the MAX512 is intended for +5V systems. Choose this component if low power consumption is critical due to its sub-1µA shutdown current. Use DAC A when higher output current sourcing/sinking is required compared to DAC B. Consider the unbuffered nature of DAC C if driving high-impedance loads directly without external amplification.

Digital To Analog Converters Part Context

This component belongs to the MAX512/MAX513 family of low-cost, triple, 8-bit voltage-output DACs. These devices are designed for portable and battery-powered applications requiring space-saving packages and ultra-low power consumption. The series integrates R-2R ladder networks with output buffer amplifiers to reduce external component count.

Digital To Analog Converters Replacement Considerations

The MAX512 serves as the +5V equivalent within the same family but requires different supply voltages. Verify pin compatibility and software register definitions when substituting between MAX512 and MAX513 variants. No other direct cross-family replacements are confirmed in the provided documentation.
