DAC532A3YBHR

Digital To Analog Converters Overview

The DAC532A3YBHR is a 10-bit smart digital-to-analog converter featuring two buffered voltage-output channels and one current-output channel. It operates within a supply voltage range of 3 V to 5.5 V and supports an industrial temperature range from –40°C to +125°C. The device integrates an internal reference, user-programmable nonvolatile memory (NVM), and a general-purpose input/output (GPIO). It automatically detects I2C or SPI interfaces, with the latter supporting up to 50 MHz. The current source offers two ranges: 300 mA and 220 mA, with a headroom of 770 mV. Voltage outputs provide gains of 1×, 1.5×, 2×, 3×, and 4×. Channel 1 can be configured as a comparator. The component is housed in a DSBGA-16 package measuring 1.72 mm × 1.72 mm.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile memory enables processor-less applications by storing predefined configurations and waveforms.
• Automatic interface detection allows seamless operation with either I2C or high-speed SPI protocols without manual configuration.
• Programmable comparator mode on Channel 1 provides force-sense capability for analog monitoring functions.

Digital To Analog Converters Applications

• Camera lens auto-focus and zoom control via voice-coil motor actuation
• Laser diode power control systems
• Tablet and Chromebook multimedia display backlighting

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix YBH corresponds to the DSBGA-16 package variant when sourcing. Confirm that the required interface protocol matches the automatic detection capabilities documented in the datasheet. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range to maintain electrical performance specifications.

Digital To Analog Converters Selection Notes

Select this component for designs requiring combined voltage and current output capabilities in a minimal footprint. The integrated NVM reduces external component count by storing startup states. Verify that the load requirements for the 300 mA current source do not exceed the thermal limits defined in the absolute maximum ratings section.

Digital To Analog Converters Part Context

This part belongs to the DAC53xAxW family, which includes the dual-channel DAC530A2W. Both variants share identical pinouts and core functionalities but differ in the number of available voltage output channels. The DAC532A3W specifically provides three active channels, whereas the DAC530A2W utilizes one channel for voltage output and leaves the corresponding pad unconnected.

Digital To Analog Converters Replacement Considerations

The DAC530A2W serves as a direct pin-compatible alternative if only two voltage outputs are required. Other members of the DAC53xAxW family may offer different channel counts or package options but require verification of register compatibility and electrical characteristics before substitution.
