Maxim Integrated MAX513CSD Low-Power, Quad, 8-Bit Voltage-Output DAC with Serial Interface

The Maxim Integrated MAX513CSD is a highly integrated digital-to-analog converter (DAC) designed for precision applications requiring compact size and low power consumption. This quad, 8-bit voltage-output DAC is an ideal solution for battery-powered devices and other systems where power efficiency is paramount. The MAX513CSD comes in a small 14-pin SO package, making it suitable for space-constrained applications.

Featuring a serial interface, the MAX513CSD enables simple and efficient communication with microcontrollers and digital systems. Its 3-wire SPI/QSPI™/MICROWIRE™-compatible serial interface allows for easy integration into a wide range of systems without the need for complex parallel connections.

One of the key advantages of the MAX513CSD DAC is its low-power operation. With a single +5V supply, it consumes a mere 160µA of operating current, and in shutdown mode, the current drops to less than 1µA, significantly extending battery life in portable applications. The DAC also features a wide power supply range from +4.5V to +5.5V, providing flexibility in various system designs.

The MAX513CSD offers excellent dynamic performance, with a fast settling time of 6µs, making it suitable for high-speed applications that require quick response times. Each of the four DAC channels has a double-buffered input, allowing simultaneous updates to all DACs or individual updates to a single DAC channel.

For added versatility, the MAX513CSD includes a software-selectable shutdown mode, which reduces power consumption when the DAC is not in use. The device also provides a clear function that resets the output to zero-scale or mid-scale, depending on the logic level of the CLR input, allowing for precise control over the output signal.

In summary, the Maxim Integrated MAX513CSD is a reliable and efficient solution for systems that require multiple DAC channels with compact size, low power consumption, and easy interfacing. Its robust feature set makes it an excellent choice for portable instruments, automatic test equipment, digital gain and offset adjustment, and industrial process controls.
