Maxim has introduced new pin- and software-compatible 16-bit (MAX5138) and 12-bit (MAX5139) precision DACs. Offered in a 3 x 3 mm package, they integrate a high-precision voltage reference and provide high linearity. Pin and software compatibility saves design time by allowing designers the capability to change resolution without redesigning the board or control software. This combination of performance and flexibility make the devices suitable for industrial process control and portable instrumentation applications, including communication systems, programmable logic controllers, servo loops and automatic test equipment.
An integrated voltage reference features a temperature coefficient of 10 ppm/°C, while the internal buffer provides improved load regulation and transition-glitch suppression for the DAC output. A pin-programmable, zero/midscale DAC output ensures that the output powers up to the desired state, even during a loss-of-power event. This output provides additional safety for applications that drive valves or other transducers that need to be off during power-up. A power-down feature reduces power consumption to just 200 nA.
These precision DACs accept a 3-wire SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface, which saves board space and reduces the complexity of optically isolated and transformer-isolated applications. To reduce the number of optocouplers in isolated applications, the serial interface features a READY output for easy daisy-chaining of multiple MAX5138/MAX5139 devices and/or other compatible devices.
The MAX5138/MAX5139 are also software compatible with the MAX5134-MAX5137 family of quad and dual, 16- and 12-bit DACs.
