12-Bit, Low-Power, Rail-to-Rail
Voltage-Output Serial DAC in SOT23

Maxim Integrated
Shutdown Modes
The MAX5712 includes three software-controlled shut-
down modes that reduce the supply current to below
1A. In two of the three shutdown modes, OUT is con-
nected to GND through a resistor. Table 1 lists the
three shutdown modes of operation.
Applications Information
Device Powered by an
External Reference
The MAX5712 generates an output voltage proportional
to VDD, coupling power supply noise to the output. The
circuit in Figure 2 rejects this power-supply noise by
powering the device directly with a precision voltage
reference, improving overall system accuracy. The
MAX6030 (+3V, 75ppm) or the MAX6050 (+5V, 75ppm)
precision voltage references are ideal choices due to
the low-power requirements of the MAX5712. This solu-
tion is also useful when the required full-scale output
voltage is less than the available supply voltages.
Digital Inputs and Interface Logic
The 3-wire digital interface for the MAX5712 is compati-
ble with SPI, QSPI, MICROWIRE, and DSP. The three
digital inputs (CS, DIN, and SCLK) load the digital input
serially into the DAC. All of the digital inputs include
Schmitt-trigger buffers to accept slow-transition inter-
faces. This allows optocouplers to interface directly to
the MAX5712 without additional external logic. The digi-
tal inputs are compatible with CMOS-logic levels.
Power-Supply Bypassing and Layout
Careful PC board layout is important for optimal system
performance. Keep analog and digital signals separate
to reduce noise injection and digital feedthrough. Use a
ground plane to ensure that the ground return from
GND to the supply ground is short and low impedance.
Bypass VDD with a 0.1F capacitor to ground as close
as possible to the device.
