DAC5574IDGSR

Digital To Analog Converters Overview

The DAC5574IDGSR is an eight-bit quad digital-to-analog converter manufactured by Texas Instruments. It features four independent voltage outputs and utilizes a two-wire I2C interface for communication. The device operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital sections. It is housed in a 16-pin TSSOP package with an exposed thermal pad. Key electrical specifications include a settling time of 3 microseconds, a maximum differential nonlinearity of ±0.01 LSB, and a maximum integral nonlinearity of ±0.25 LSB. The part supports a sampling rate of 55.55 kS/s per channel.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing I2C bus addressing schemes during integration. Confirm operating temperature range requirements match the industrial grade specifications provided in the datasheet before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when multiple low-resolution voltage outputs are required in space-constrained designs. Compare settling time and linearity specifications against application requirements. Consider the TSSOP package dimensions for PCB layout constraints. Evaluate power consumption levels relative to battery life expectations in portable applications.

Digital To Analog Converters Part Context

This device belongs to the DAC557x family of low-power, 8-bit digital-to-analog converters. The family shares common architectural features including I2C compatibility and buffered outputs. Variations within the series typically differ by channel count and package options. This specific model provides a quad-channel solution suitable for cost-sensitive multi-output applications.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes may exist within the same manufacturer's portfolio. Verify equivalent channel counts and interface protocols before substitution. Check for differences in settling time or linearity that might impact system performance. Confirm package dimensions match the existing footprint if mechanical constraints are strict.
