AD5024BRUZ

Digital To Analog Converters Overview

The AD5024BRUZ is a quad, 12-bit buffered voltage output nanoDAC from Analog Devices. It operates on a single 4.5 V to 5.5 V supply and features individual reference pins for each channel. The device offers ±0.5 LSB INL and ±0.2 LSB DNL with a total unadjusted error of ±2 mV. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 50 MHz. Integrated reference buffers and output amplifiers provide rail-to-rail operation. Power consumption is typically 4 mA in normal mode and reduces to 400 nA in power-down modes.

Digital To Analog Converters Feature Summary

• Quad-channel 12-bit resolution with ±0.5 LSB INL and ±0.2 LSB DNL
• Individual reference input pins (VREFA, VREFB, VREFC, VREFD)
• 3-wire serial interface with SCLK up to 50 MHz
• Power-on reset to zero scale or midscale via POR pin

Digital To Analog Converters Applications

• Process control systems
• Data acquisition systems
• Portable battery-powered instruments
• Digital gain and offset adjustment
• Programmable voltage and current sources

Digital To Analog Converters Procurement Notes

Verify the specific grade (A or B) and package variant when ordering, as performance specifications vary between grades. Confirm that the application requires the 16-lead TSSOP package with individual reference pins, distinct from the common reference AD5064-1 variant. Ensure supply voltage constraints align with the 4.5 V to 5.5 V operating range.

Digital To Analog Converters Selection Notes

Select the AD5024BRUZ for applications requiring four independent 12-bit channels with high accuracy. The B grade offers tighter linearity specifications compared to the A grade. Consider the external reference requirement, as this model lacks an internal reference generator but provides dedicated pins for individual channel referencing. Verify thermal management needs given the 113°C/W junction-to-ambient thermal impedance.

Digital To Analog Converters Part Context

The AD5024BRUZ belongs to the nanoDAC family, serving as a low-power alternative to higher-resolution models like the AD5044 (14-bit) and AD5064 (16-bit). It is pin-compatible with the AD5666 but offers superior accuracy. The BRUZ suffix indicates the B grade performance level and the 16-lead TSSOP package configuration.

Digital To Analog Converters Replacement Considerations

The AD5666 is a pin-compatible upgrade target if lower accuracy (16 LSB INL) is acceptable. For higher resolution, the AD5044BRUZ (14-bit) and AD5066BRUZ (16-bit) are direct functional replacements within the same package, maintaining the individual reference pin architecture.
