Maxim Integrated MAX5158CEE+T Dual, 10-Bit, Low-Power, Voltage-Output DACs with Serial Interface

The MAX5158CEE+T from Maxim Integrated is a high-performance, dual 10-bit digital-to-analog converter (DAC) designed to deliver precision voltage outputs with low power consumption. This device is an ideal choice for a wide range of applications, including automatic tuning, adjustable power supplies, and digital gain and offset adjustment circuits.

The MAX5158CEE+T features a serial interface that allows for easy communication with microcontrollers or digital signal processors. Each of the two DACs can be independently programmed via the three-wire serial interface, which is compatible with SPI, QSPI™, and MICROWIRE™ protocols, ensuring flexibility and ease of integration into existing systems.

With a 2.7V to 5.5V single supply voltage range, the MAX5158CEE+T is versatile and can be used in both portable and fixed supply applications. The device also boasts a low power consumption of just 180µA (typical) at 5V, making it an excellent choice for battery-powered devices where power efficiency is critical.

The MAX5158CEE+T comes in a compact 16-pin QSOP package, which is suitable for space-constrained applications. Additionally, it features a power-on reset circuit that ensures the DAC outputs power up to zero volts and remain there until a valid write to the device takes place. This feature provides additional safety for applications that require a known startup state.

Other key features of the MAX5158CEE+T include a buffered voltage output that can directly drive 60kΩ loads, and an internal reference that provides a full-scale output voltage range of 4.095V. For applications requiring an external reference, the device can also be configured to accept an external reference voltage, offering flexibility in setting the full-scale output voltage.

In summary, the MAX5158CEE+T is a highly versatile and efficient dual-channel DAC that provides precise voltage outputs, low power consumption, and easy interfacing capabilities, making it a top choice for designers looking to add analog functionality to their digital systems.

Note: Maxim Integrated is now part of Analog Devices, following their merger.
