MAX547BCMH

The MAX547BCMH is an octal, 13-bit digital-to-analog converter (DAC) from Analog Devices, designed for voltage-output applications. It integrates eight 13-bit DACs with on-chip precision output amplifiers, enabling bipolar output voltages up to ±4.5V without external components. The device operates from a ±5V supply.

The MAX547BCMH features a double-buffered digital interface with a 13-bit parallel data bus. Each DAC has an input latch and a DAC latch, with data loaded via a single write instruction. Asynchronous load inputs update pairs of DAC latches, and an asynchronous clear input resets all DAC outputs to analog ground. The device offers calibrated linearity and guaranteed monotonicity to 13 bits, with a fast output settling time of 5µs to ±1⁄2 LSB.

This DAC is available in a 44-pin MQFP package suitable for surface mounting. Its architecture is R-2R, and it requires external voltage references. The operating temperature range is 0°C to 70°C.

Applications for the MAX547BCMH include automatic test equipment, minimum component-count analog systems, digital offset/gain adjustment, arbitrary function generators, industrial process controls, and avionics equipment.
