Maxim Integrated MAX509BEWP+ Product Overview

The MAX509BEWP+ from Maxim Integrated is a precision, low-power, quad 8-bit voltage-output digital-to-analog converter (DAC) designed to deliver high-performance in a compact package. This device is ideal for applications requiring multiple DACs on a single chip, such as process control, automatic tuning, and adjustable power supplies.

Featuring a 4-wire serial interface that saves board space and reduces power consumption, the MAX509BEWP+ operates from a single +2.7V to +5.5V supply. Each of the four DACs can be individually set to a reference voltage, allowing for a wide range of output voltages suitable for various applications. The DAC outputs are buffered with a x1 gain, providing a full-scale output voltage range from 0V to VREF.

The device comes in a 20-pin WSOIC (Wide Small Outline Integrated Circuit) package, which is known for its space-saving footprint. This makes the MAX509BEWP+ an excellent choice for space-constrained applications. The DAC's power-on reset circuit ensures that the DAC outputs power up to zero volts and remain there until a valid write to the device takes place. This feature prevents any unwanted signals during power-up, contributing to system stability and reliability.

Key features of the MAX509BEWP+ include low power operation, with each DAC consuming just 160µA at 5V. Additionally, the device boasts a fast settling time, making it suitable for high-speed applications that require quick response times. The MAX509BEWP+ also incorporates a power-down mode, which reduces power consumption to 4µA at 5V, further extending battery life in portable applications.

Overall, the MAX509BEWP+ is a versatile and efficient solution for systems that require multiple high-performance DACs. Its combination of low power consumption, compact size, and precision output makes it a valuable component for designers looking to optimize their analog output capabilities in a range of electronic products.
