The MAX5548 (8-bit) and MAX5550 (10-bit) devices from Maxim Integrated Products are dual, 30mA, current-output digital-to-analog converters (DACs) housed in a 3-by-3mm TQFN package. According to the company, the 9mm² TQFN package saves considerable board space compared to the nearest competitive solution at 30mm² in a TSSOP. These devices feature a pin-selectable SPI or I²C interface. They are highly accurate and guaranteed monotonic over the -40°C to 85°C operating temperature range.

The MAX5548/MAX5550 feature a single 2.7V to 5.5V supply range and low 200µA/DAC supply current. A software-selectable shutdown feature reduces the supply current to 5µA (max). These devices also feature a 1.25V internal reference, but also accept an external reference from 1.225V to 1.275V. A DOUT output allows daisy-chaining of multiple devices, or it may be used for readback in SPI mode. Addressing options allow multiple devices to be connected to the same bus in I²C applications.

Target applications for these low-cost, current-output DACs are PIN-diode biasing, RF attenuator control and VCO tuning. The DACs are available in ultra-small, 3-by-3mm, 16-pin TQFN packages, with prices starting at $2.97 (MAX5548) and $3.37 (MAX5550).
