Introduction

TLC7733QD is a precision 19-bit digital-to-analog converter (DAC) designed to provide ultra-low power operation in point of load applications such as microprocessor core and peripheral voltage applications. This PMIC -Supervisors series device is suitable for various industrial, consumer, and automotive products design. Ultra-low supply current (1μA typical) over a wide input voltage range (2.3V to 5.5V), make TLC7733QD an ideal solution for battery-powered portable applications requiring low-noise and low-drift accuracy.

Application Fields

TLC7733QD is widely used in different industries. It is used for precise voltage transformations and currents in consumer, automotive and industrial applications. For example, portable consumer applications such as MP3 players, digital cameras, and cell phones can benefit from TLC7733QD’s low power consumption, accuracy and precise voltage transformation. Automotive applications such as ECUs, body control modules, and engine management systems can benefit from the device’s durable ESD protection and stability. In industrial applications, TLC7733QD is perfect for use in CCTV surveillance systems, gas leak detectors, and proximity sensors.

Features

The TLC7733QD PMIC - Supervisors series device has the following unique features:

• 19-bit high-resolution DAC with 0.3μV DAC bit resolution
• Only 2mA DAC supply current consumption
• Totally Settling Time of 10μs to 0.01% accuracy
• 9-bit output amplifier (maximum peak to peak output amplitude of 19V)
• Wide output voltage range (2.3V to 5.5V)
• Ultra-low power consumption
• Extremely low Total Harmonic Distortion (THD)
• ESD protection for all pins
• Uses I2C digital interface

Working Principle

The device works when the DAC registers are addressed via the I2C bus. The addressed registers are then loaded with the digital output value. The clock frequency and duty cycle can be programmable, so that the device can be tuned from 0.1% accuracy up to 0.01% accuracy.The output of the TLC7733QD is a Voltage or current value, via the output buffer or amplifier. The output voltage is set by the user defined, fixed division of the DAC reference voltage. The maximum peak-to-peak output amplitude is 19V. The output ranges from -9V to +10V.The output current is also versatile and can range anywhere from 0mA to 14mA. The output current is proportional to the output voltage and can be configured using the integrated current source and resistor.

Conclusion

TLC7733QD PMIC - Supervisors series device is built to deliver low-noise and low-drift accuracy. It is a robust 19-bit DAC device suitable for precision voltage and current transformations in a variety of applications. It is an ideal solution for battery-powered portable applications requiring extreme accuracy and power efficiency.
