The MAX5173AEEE+ is a versatile digital-to-analog converter (DAC) from Maxim Integrated. The chip provides high-precision, 16-bit resolution DAC performance with low power and wide operating temperature ranges. The MAX5173AEEE+ is an optimum choice for high-precision, low-voltage applications that require both DAC speed and accuracy.

The MAX5173AEEE+ offers excellent linearity performance, with an integral nonlinearity (INL) of ±1LSB (max) over full-scale. In addition, low temperature coefficient of ±5ppm/°C allows the device to maintain its performance over a wide operating temperature range, from -40°C to +125°C. It also provides excellent power supply rejection (PSRR) of 88dB and fast settling time of 17µs to 0.001% of full-scale (FS).

The MAX5173AEEE+ is available in the space-saving TQFN-14 package, making it ideal for space-constrained applications. It also offers high integration, with an efficient voltage-out loop, an integrated voltage reference and an onboard high-speed, voltage switch controlled digital-to-analog converter (DAC) output regulator.

The MAX5173AEEE+ is designed for use in a variety of high-precision applications, such as test and measurement systems, medical equipment, industrial sectors, and general purpose embedded applications.

The way the MAX5173AEEE+ works is quite straightforward. The device converts digital input codes into an analog voltage output. The DAC requires two different references for its operation. An external reference voltage is used to determine the full-scale output voltage, and an internal reference voltage is used to establish the mid-scale ground reference. The output voltage can be programmed via three-wire serial control interface, which consists of a data-clock (SCLK) and a data-in (DIN) interface pins.

The chip is connected to an external voltage reference, which determines the output voltage range. An internal voltage reference is also connected to the chip, which establishes the mid-scale ground reference level. The digital-to-analog converter then uses the external reference voltage to determine the full-scale output voltage range and the internal reference voltage to establish the mid-scale ground reference level. The output voltage is then programmed by the digital input code, which is converted into an analog voltage output.

The chip also has an internal glitch-free comparator that detects the voltage output and switches off the DAC output when the voltage exceeds the full-scale voltage of the DAC. This protects the device from any overvoltage damage.

The MAX5173AEEE+ offers excellent linearity performance, low power consumption, high precision, wide operating temperatures range, on-board voltage switching controlled DAC output regulator and its capability of integrating with other applications. With its advanced feature set and its reliable performance, the MAX5173AEEE+ is an excellent choice for applications requiring precision and accuracy.
