MAX509BCWP

Digital To Analog Converters Overview

The MAX509BCWP is a quad, 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features rail-to-rail buffered voltage outputs and an R-2R resistor ladder architecture. The device supports serial interfaces including SPI, Microwire, and QSPI. It operates on a single 5V supply with a maximum power supply voltage of 5.5V. Key electrical parameters include a settling time of 6µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. The component is housed in a 20-pin SSOP package and is rated for operation between 0°C and +70°C.

Digital To Analog Converters Feature Summary

• Quad-channel 8-bit resolution with rail-to-rail buffered outputs
• Flexible serial interface compatibility: SPI, Microwire, QSPI, 3-Wire, and 4-Wire
• High accuracy with ±1 LSB DNL and INL specifications
• Fast settling time of 6µs

Digital To Analog Converters Applications

• Portable instrumentation systems requiring multiple analog outputs
• Battery-powered equipment due to low power consumption characteristics
• Industrial process control loops
• Programmable gain amplifiers and variable voltage references

Digital To Analog Converters Procurement Notes

The MAX509BCWP is listed as obsolete or end-of-life by the manufacturer. Verification of current stock availability through authorized distributors is required before procurement planning. Alternative sources may only offer surplus or secondary market inventory. Designers should assess long-term supply risks associated with discontinued components for new production runs.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, 8-bit DAC with rail-to-rail output swing is necessary within a 5V system. Ensure the application requires serial communication compatible with SPI or Microwire protocols. Verify that the operating temperature range of 0°C to +70°C meets environmental constraints. Consider the SSOP-20 package dimensions for PCB layout compatibility.

Digital To Analog Converters Part Context

This part belongs to the MAX509B series of high-performance, low-power DACs. It shares architectural similarities with other members like the MAX509BEWP but differs in packaging (SSOP vs. SOIC) and temperature grade (Commercial vs. Extended). The 'C' suffix typically denotes the commercial temperature range. It serves as a compact solution for multi-channel signal generation in space-constrained designs.

Digital To Analog Converters Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source data. Engineers should consult official replacement guides from Analog Devices/Maxim Integrated for pin-compatible or functionally equivalent alternatives suitable for obsolescence management.
