MAX509BCWP+T

Digital To Analog Converters Overview

The MAX509BCWP+T 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 supply or dual ±5V supplies and features internal precision buffers that swing rail-to-rail. The device includes four separate reference inputs, allowing each DAC's full-scale range to be set independently. It offers calibrated offset, gain, and linearity with a total unadjusted error of ±1.5 LSB. The serial interface supports MICROWIRE, SPI, and QSPI protocols at speeds up to 10MHz.

Digital To Analog Converters Feature Summary

• Quad 8-bit DACs with rail-to-rail output buffers
• Independent reference inputs for each channel
• ±1.5 LSB Total Unadjusted Error (TUE)
• Compatible with MICROWIRE, SPI, and QSPI interfaces

Digital To Analog Converters Applications

• Industrial process control systems
• Programmable power supplies
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCWP' corresponds to the commercial temperature range (0°C to +70°C) and Wide SOIC-20 package. Confirm RoHS compliance status as indicated by the '+' suffix. Check current availability through authorized distributors as lead times may vary.

Digital To Analog Converters Selection Notes

Select this component when independent reference control for all four channels is required. Ensure the system operates within the specified voltage ranges (+4.5V to +5.5V for VDD). Verify that the serial interface timing requirements align with the microcontroller's capabilities.

Digital To Analog Converters Part Context

This part belongs to the MAX509/MAX510 family of quad serial DACs. The MAX509 variant provides four distinct reference inputs, whereas the MAX510 shares two references among four channels. The 'B' grade indicates a ±1.5 LSB TUE specification, while the 'C' grade offers ±1 LSB.

Digital To Analog Converters Replacement Considerations

Direct replacements include other MAX509 variants with different packages (e.g., MAX509ACAP+ for SSOP) or grades (MAX509ACWP+ for ±1 LSB TUE). Ensure pin compatibility and electrical specifications match the design requirements.
