The MAX5134 is a low-power, quad 16-bit, buffered voltage-output, high-linearity digital-to-analog converter (DAC). It uses a precision internal reference or a precision external reference for rail-to-rail operation. The MAX5134 accepts a wide +2.7V to +5.25V supply-voltage range to accommodate most low-power and low-voltage applications. The device accepts a 3-wire SPITM-/QSPITM-/MICROWIRETM-/DSP-compatible serial interface to save board space and reduce the complexity of optically isolated and transformer-isolated applications. The digital interface’s double-buffered hardware and software LDAC provide simultaneous output update. The serial interface features a READY output for easy daisy-chaining of several MAX5134 devices and/or other compatible devices. The MAX5134 includes a hardware input to power-up or reset the DAC outputs to zero or midscale, providing additional safety for applications that drive valves or other transducers that need to be off dur- ing power-up. The high linearity of the DACs makes these devices ideal for precision control and instrumen- tation applications. The MAX5134 is available in an ultra-small (4mm x 4mm), 24-pin TQFN package and is specified over the -40°C to +105°C extended industrial temperature range. Applications include Automatic Test Equipment, Automatic Tuning, Communication Systems, Data Acquisition, Gain and Offset Adjustment, Portable Instrumentation, Power-Amplifier Control, Process Control and Servo Loops.
The MAX5134 is a low‑power, quad 16‑bit buffered voltage‑output DAC designed for precision control and instrumentation. It operates from a +2.7 V to +5.25 V supply and supports a 3‑wire SPI/QSPI/MICROWIRE/DSP‑compatible serial interface with a READY output for daisy‑chaining.
The device offers high linearity, a hardware‑selectable power‑up reset, and an internal reference with 10 ppm/°C temperature coefficient. It is available in a 4 mm × 4 mm, 24‑pin TQFN package and is rated for –40 °C to +105 °C industrial temperature range.
