MAX520BCPE

Digital To Analog Converters Overview

The MAX520BCPE is a quad, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single +5V supply with an external reference input range spanning the supply rails. The device features unbuffered outputs and utilizes a simple 2-wire serial interface compatible with I2C protocols for data rates up to 400kbps. Key electrical parameters include a resolution of 8 bits, a settling time of 2µs, and a supply current of 4µA in normal operation. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at ±1 LSB maximum.

Digital To Analog Converters Feature Summary

• Quad-channel 8-bit DAC architecture with unbuffered voltage outputs
• Simple 2-wire serial interface compatible with I2C standards
• Ultra-low power consumption with 4µA operating current
• Individual reference inputs for each DAC channel

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCPE' corresponds to the 16-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the part number matches the unbuffered output variant, distinct from the buffered MAX521 series. Ensure compatibility with existing I2C bus architectures requiring pull-up resistors if necessary.

Digital To Analog Converters Selection Notes

Select this component when a low-cost, quad-channel DAC with minimal external components is required. The unbuffered output design reduces supply current compared to buffered variants but requires consideration of load impedance. Verify that the system can accommodate separate reference inputs for each channel rather than a shared reference structure.

Digital To Analog Converters Part Context

The MAX520 belongs to a family of quad and octal 8-bit DACs featuring rail-to-rail outputs. While the MAX521 offers buffered outputs for higher drive capability, the MAX520 prioritizes low power consumption through its unbuffered design. Both share the same serial interface protocol and pinout compatibility within their respective package types.

Digital To Analog Converters Replacement Considerations

Direct replacements include other MAX520 variants with different temperature grades or packages, such as MAX520ACPE or MAX520AEWE. For buffered output requirements, the MAX521 series serves as a functional alternative, though it consumes more power.
