MAX512CSD+T

Digital To Analog Converters Overview

The MAX512CSD+T is a triple, 8-bit voltage-output digital-to-analog converter (DAC) in a 14-pin SO package. It integrates two buffered outputs (DAC A and DAC B) and one unbuffered output (DAC C). The device operates on a single +5V ±10% supply or split supplies. It features a 3-wire serial interface compatible with SPI, QSPI, and Microwire standards, supporting clock frequencies up to 5MHz. Key electrical parameters include ±1 LSB maximum differential nonlinearity (DNL), ±1.5 LSB integral nonlinearity (INL) for the buffered channels, and a typical settling time of 70µs to ±1/2LSB. Operating current is 1mA, reducing to less than 1µA in shutdown mode.

Digital To Analog Converters Feature Summary

• Triple 8-bit DAC architecture with two buffered outputs (DAC A/B) and one high-accuracy unbuffered output (DAC C)
• 5MHz 3-wire serial interface compatible with SPI, QSPI, and Microwire protocols
• Low power consumption: 1mA operating current and <1µA shutdown current
• Independent programmable shutdown mode for each DAC channel

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging and '+' confirms lead-free/RoHS compliance. Confirm the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure the specific lot date code meets project requirements as manufacturing dates vary by batch.

Digital To Analog Converters Selection Notes

Select this component when three independent 8-bit DAC channels are required in a small footprint. Choose MAX512 over MAX513 if the system design utilizes a standard +5V supply rail rather than a +3V rail. Consider the unbuffered nature of DAC C for driving high-impedance loads where low output impedance is not critical.

Digital To Analog Converters Part Context

This part belongs to the MAX512/MAX513 family of low-cost, triple DACs manufactured by Maxim Integrated. The MAX512 variant is optimized for +5V operation, while the MAX513 supports lower voltage ranges. The MAX512CSD+T specifically denotes the commercial grade version housed in a 14-pin Small Outline package.

Digital To Analog Converters Replacement Considerations

The MAX513CSD+T serves as a direct pin-compatible alternative for systems requiring +3V operation instead of +5V. Other members of the MAX512/MAX513 family share identical pinouts and software compatibility.
