MAX5832GWX+

Digital To Analog Converters Overview

The MAX5832GWX+ is a 14-bit, 9-channel current-output digital-to-analog converter (DAC) designed for low-voltage operation. It operates from a +3.0V analog supply and features an internal reference. The device includes nine independent channels with varying full-scale currents: OP1/OP2 provide 10mA; OP3 offers selectable 2mA or 20mA; OP4 and OP7 provide 90mA; OP5 provides 180mA; OP6 supports ±300mA sourcing/sinking; OP8/OP9 offer selectable 15mA or 35mA. Channels 1 and 2 include integrated multiplexers. It utilizes an I2C-compatible interface with clock rates up to 400kHz and operates over a temperature range of -40°C to +105°C in a 3mm x 3mm WLP package.

Digital To Analog Converters Feature Summary

• Integrated multiplexers on outputs 1 and 2 allow routing to four external nodes.
• Selectable full-scale output ranges for specific channels enable flexible biasing configurations.
• Track-and-hold circuitry reduces glitch impulse during code transitions.
• Programmable DAC ground switches connect outputs to ground at zero code.

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the component revision and RoHS compliance status against the manufacturer's latest documentation before integration. Confirm that the WLP package thermal characteristics meet the system's dissipation requirements under maximum operating conditions. Ensure the I2C bus voltage levels are compatible with the host controller logic supplies.

Digital To Analog Converters Selection Notes

Select this component when a high channel count with varied current capabilities is required in a minimal footprint. The integrated multiplexers on channels 1 and 2 simplify board layout for multi-node applications. Consider the track-and-hold feature if minimizing transient glitches is critical for signal integrity. Verify that the negative supply requirement for OP6 aligns with the system power architecture.

Digital To Analog Converters FAQ

How does the track-and-hold function improve performance?

The track-and-hold circuit engages after the serial interface frame completes, holding the output level until the DAC settles. This significantly reduces glitch impulse during major code transitions by ensuring updates occur only when the output is stable.

What is the function of the CLR input?

The active-high asynchronous CLR input allows independent configuration of each DAC's response. Options include ignoring the signal, shutter mode for OP6, gate mode to hold at zero, or reset mode to force zero code permanently until cleared.

Can DAC outputs be connected in parallel?

Yes, connecting DAC outputs in parallel increases the total available current drive or improves resolution. The datasheet notes this capability for achieving higher performance than individual channel limits.
