Maxim Integrated MAX528CPP: 8-Channel, 8-Bit DAC with Internal Reference

The MAX528CPP from Maxim Integrated is a sophisticated 8-channel, 8-bit digital-to-analog converter (DAC) designed to cater to a wide array of applications that require multiple DACs in a compact form factor. This high-performance component is ideal for systems that demand low-power consumption and high-precision analog output control.

Encased in a 20-pin DIP (Dual In-line Package), the MAX528CPP integrates eight voltage-output DACs and an internal precision bandgap reference in a single chip, providing a complete analog output solution for embedded systems. The internal reference has a 4.096V output, ensuring stable and accurate performance across the entire operating range.

One of the outstanding features of the MAX528CPP is its serial interface, which is compatible with SPI, QSPI™, and MICROWIRE™ protocols, offering versatility in communication with microcontrollers or microprocessors. This digital interface minimizes the number of wires needed for connection, simplifying the design and reducing the overall system footprint.

The device operates from a single +4.75V to +5.25V supply voltage, making it suitable for 5V systems. Furthermore, it boasts a low power consumption of just 1.5mA, which drops to 1µA in power-down mode, making it an energy-efficient choice for battery-operated devices.

Each of the eight DAC channels on the MAX528CPP can be individually programmed with a 2-wire serial interface, allowing for precise control over each output. The DACs can be updated individually or simultaneously, offering flexibility for dynamic adjustments. The device also features a double-buffered interface, enabling the user to pre-load multiple DAC registers with new values and update all outputs simultaneously with a single command.

Applications for the MAX528CPP are diverse and include process control, automatic test equipment, digital gain and offset adjustment, and programmable power supplies. With its combination of multiple DAC channels, integrated precision reference, low power consumption, and serial interface, the MAX528CPP is a robust solution for designers looking to streamline their analog output requirements.

Maxim Integrated's commitment to quality ensures that the MAX528CPP is a reliable and high-performing component for your analog output needs.
