MAX509BEWP+T

Digital To Analog Converters Overview

The MAX509BEWP+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 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 ±1.5 LSB, an output settling time of 6µs, and a power-on reset function that clears the serial interface and sets all registers to zero.

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 of multiple devices

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring precise analog scaling
• Multi-channel data acquisition systems needing synchronized updates
• Industrial process control loops utilizing serial bus interfaces
• Battery-powered instrumentation leveraging low-power CMOS logic compatibility

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCWP' corresponds to the Wide SO package and ±1.5 LSB TUE grade. Confirm RoHS compliance status as indicated by the '+' designation. Check current availability status as this component may be subject to discontinuation notices from Analog Devices/Maxim Integrated.

Digital To Analog Converters Selection Notes

Select the MAX509 variant over MAX510 when independent reference voltages are required for all four channels. Ensure the system clock frequency does not exceed the 10MHz limit for specified performance. Verify that the load impedance and capacitance requirements align with the 6µs settling time specification under single or dual supply configurations.

Digital To Analog Converters Part Context

This component belongs to the MAX509/MAX510 family of quad serial DACs. The MAX509 provides four distinct reference inputs, whereas the MAX510 shares references between pairs of DACs. Both families utilize identical serial interface protocols and buffer architectures, differing primarily in reference input flexibility and pin count variations across DIP, SSOP, and SO packages.
