MAX512CPD+

Digital To Analog Converters Overview

The MAX512CPD+ is a triple 8-bit voltage-output digital-to-analog converter in a 14-pin plastic DIP package. It operates from a single +5V supply (4.5V to 5.5V) or split supplies. The device integrates two buffered outputs (DAC A and DAC B) and one unbuffered output (DAC C). DAC A provides up to 5mA drive capability, while DAC B supports 0.5mA. It features a 3-wire serial interface compatible with SPI, QSPI, and Microwire protocols, operating at frequencies up to 5MHz. Key electrical parameters include an 8-bit resolution, ±1 LSB DNL, ±1.5 LSB INL for DACs A/B, and a typical settling time of 70µs.

Digital To Analog Converters Feature Summary

• Triple 8-bit architecture with two buffered outputs (DAC A/B) and one unbuffered output (DAC C)
• Single +5V operation range (4.5V to 5.5V) with low power consumption (1mA active, <1µA shutdown)
• 5MHz 3-wire serial interface compatible with SPI, QSPI, and Microwire standards
• Independent programmable shutdown mode for each DAC channel

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CPD+' against the manufacturer's official documentation to confirm the 14-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Ensure that the ordering information matches the required supply voltage specifications for the MAX512 variant rather than the MAX513. Cross-reference the datasheet revision date to confirm pinout and electrical characteristic consistency.

Digital To Analog Converters Selection Notes

Select this component when a triple-channel DAC solution is required within a 14-pin footprint. The MAX512 variant is appropriate for systems requiring a stable +5V supply. Consider the drive capabilities: use DAC A for loads requiring up to 5mA and DAC B for loads up to 0.5mA. For high-impedance loads requiring faster dynamic response, utilize the unbuffered DAC C channel. Verify compatibility with the host microcontroller's serial protocol settings (CPOL=0, CPHA=0 for SPI).

Digital To Analog Converters Part Context

The MAX512/MAX513 series consists of low-cost, triple 8-bit voltage-output DACs designed for portable and battery-powered applications due to their ultra-low power consumption. The MAX512 is optimized for +5V systems, whereas the MAX513 supports lower voltage ranges (2.7V to 3.6V). Both share identical pinouts and functional architectures, differing primarily in supply voltage specifications and operating temperature ranges defined by their suffixes.
