What are the key features of DAC5574IDGSG4?
- 4 independent 8-bit DAC channels on a single I2C bus reduce GPIO and wiring count in multi-channel analog control systems
- 5.5 V output swing and 0.2% linearity error deliver precise voltage references for sensor calibration and gain adjustment
- Power-down mode reduces supply current to under 1 µA per channel, extending battery life in portable analog control designs
What is DAC5574IDGSG4 used for?
The DAC5574IDGSG4 is used in industrial process controllers, programmable gain amplifier biasing, and sensor calibration systems where 4 independent 8-bit analog output channels are needed on a single I2C bus. Its 5.5 V output range and 0.2% linearity make it suitable for setting reference voltages in 4-20 mA loop transmitters and PID controller set-points. Medical instrumentation and portable test equipment use it for its low power consumption and compact 10-pin MSOP footprint.

Frequently Asked Questions
How many DAC5574IDGSG4 devices can share a single I2C bus and how is each device addressed?
Up to 4 DAC5574IDGSG4 devices can share a single I2C bus by using the 2 address select pins (A0, A1) to configure unique 7-bit I2C addresses from 0x48 to 0x4B. Each device provides 4 DAC channels, so a 2-wire I2C bus connecting 4 devices drives 16 independent 8-bit analog outputs, covering 16 process control loops or sensor biasing channels from a microcontroller with only 2 dedicated I2C pins.
What output voltage resolution does the DAC5574IDGSG4 provide on a 5 V reference and how does that compare to a 12-bit alternative?
On a 5 V reference, the 8-bit DAC5574IDGSG4 provides 256 output steps of approximately 19.5 mV each (5 V ÷ 256), with a ±0.5 LSB linearity error translating to ±9.8 mV worst-case accuracy. A 12-bit DAC on the same reference yields 4096 steps of 1.22 mV each, offering 16× finer resolution. For applications requiring better than 20 mV set-point accuracy — such as a ±1% calibration trim on a 1 V sensor output — the 12-bit alternative is necessary; the DAC5574IDGSG4 is preferred when cost and I2C simplicity outweigh resolution requirements.
In a 4-20 mA industrial loop transmitter design, how does the DAC5574IDGSG4 set the loop current and what is the achievable current step resolution?
The DAC5574IDGSG4 outputs a 0 V to 5.5 V voltage that drives a voltage-to-current converter circuit, typically an op-amp with a 250 Ω sense resistor, to generate the 4 mA to 20 mA loop signal. With 8-bit resolution over a 16 mA span, each DAC code step represents approximately 62.5 µA of loop current change. This corresponds to a process variable resolution of 0.39% of full scale (1/256), meeting the ±0.5% accuracy class required by IEC 61298-2 for Class B industrial transmitters.
