MAX509AEWP+

Digital To Analog Converters Overview

The MAX509AEWP+ is a quad, serial-input, 8-bit voltage-output digital-to-analog converter (DAC) housed in a 20-pin Wide SO package. It operates with a single +5V or dual ±5V supply and features internal precision buffers that swing rail-to-rail. The device includes four separate reference inputs, allowing independent full-scale range setting for each DAC. It supports a 10MHz serial interface compatible with SPI, QSPI, and Microwire protocols. Key electrical characteristics include a Total Unadjusted Error (TUE) of ±1 LSB, an output settling time of 6µs, and an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Quad 8-bit DAC architecture with rail-to-rail buffered outputs
• Independent reference inputs for individual channel full-scale control
• Double-buffered registers enabling synchronous updating via LDAC or software commands
• Serial data output (DOUT) supporting daisy-chaining and readback capabilities

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable gain amplifiers and variable voltage references
• Battery-powered instrumentation utilizing single-supply operation
• Data acquisition systems interfacing with microprocessors via SPI/Microwire

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' confirms the extended commercial temperature range of 0°C to +70°C as defined in the ordering information table. Confirm the 'WP' designation corresponds to the 20-pin Wide SOIC package. Ensure compatibility with existing PCB footprints for this specific package variant before procurement.

Digital To Analog Converters Selection Notes

Select the MAX509AEWP+ when independent reference voltages are required for each of the four channels, distinguishing it from the MAX510 which shares references. Choose this component over the MAX509AEEP+ if surface-mount assembly is preferred over through-hole DIP packaging. Verify that the 8-bit resolution and ±1 LSB TUE meet the system accuracy requirements.

Digital To Analog Converters Part Context

The MAX509AEWP+ belongs to the MAX509/MAX510 family of quad serial DACs. It is functionally identical to the MAX509A but differs in package type (Wide SO vs. PDIP) and potentially thermal characteristics. The 'E' suffix denotes the 0°C to +70°C temperature grade, while 'C' variants offer lower cost specifications.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same series include MAX509ACWP+ and MAX509BCWP+, though these have different accuracy grades (±1 LSB vs ±1.5 LSB TUE). Cross-package alternatives like MAX509AEPP+ require adapter solutions due to DIP packaging differences.
