MAXIM Integrated Products, represented by Arrow , has introduced the MAX5510 to MAX5515, MAX5520 to MAX5525 and the MAX5530 to MAX5535.

These devices are eight, ten and 12-bit, single and dual micropower DACs (digital to analogue converters) that use only 5μA/DAC (max) supply current.

These devices operate from supply voltages as low as 1.8V to 5.5V. Their ultra-low supply current and 1.8V supply voltage make them suitable for direct battery-powered equipment such as medical devices, sensors, and consumer electronics.

The MAX5510 to MAX5515, MAX5520 to MAX5525 and MAX5530 to MAX5535 contain a precision, internal voltage reference that saves board space by not requiring a separate external reference. The reference output's 8mA source current allows these devices to power surrounding circuitry or be used as a reference for other data converters.

Available in ten-pin microMAX and 12-pin, 4mm x 4mm QFN packages, the devices are suitable for space-constrained and low-power systems.

These DACs are guaranteed to be monotonic. They have a 16MHz low-power SPI-/QSPI-/MICROWIRE-compatible three-wire serial interface, and a preconfigured force-sense or unity-gain output-buffer configuration.
