... Rev 0; 7/08 General Description The MAX5134 is a low-power, quad 16-bit, buffered volt- age-output, high-linearity digital-to-analog converter (DAC). It uses a precision internal reference or a preci- sion external reference for rail-to-rail operation. The MAX5134 accepts a wide +2.7V to +5.25V supply-volt- age range to accommodate most low-power and low- voltage applications ...

... SCLK and DIN input buffers after completion of each 24-bit serial input. On power- up, the MAX5134 resets the DAC outputs to zero or mid- scale, depending on the state of the M/Z input, providing additional safety for applications that drive valves or other transducers that need to be off on power-up ...

... Connect AVDD to REFI to use AVDD as the reference voltage. Leave REFO unconnected. The MAX5134 3-wire serial interface is compatible with MICROWIRE, SPI, QSPI, and DSPs (Figures 2, 3). The interface provides three inputs, SCLK, CS, and DIN and one output, READY. Use READY to verify communica- tion or to daisy-chain multiple devices (see the READY section) ...

... Connect READY to a microcontroller (µC) input to moni- tor the serial interface for valid communications. The READY pulse appears 24 clock cycles after the nega- tive edge of CS (Figure 4). Since the MAX5134 looks at the first 24 bits of the transmission following the falling edge of CS possible to daisy chain devices with different command word lengths ...

... DAC register holds the retained code so that the output is restored when the channel powers up. The serial interface remains active in power-down mode. The MAX5134 features an active-low LDAC logic input that allows the outputs to update asynchronously. Keep LDAC high during normal operation (when the device is controlled only through the serial interface) ...
