Product details

What this 7-bit current DAC actually does

The Maxim Integrated DS4432U+T&R is a 7-bit digital-to-analog converter (DAC) with a current output, not the more common voltage output. Its architecture is a current sink and current source, meaning each of its two DAC channels can either pull current to ground (sink) or push current out (source), depending on the code written over the I2C interface. The output is unbuffered, so the load impedance directly sets the voltage compliance range. This part is designed for trimming and calibration applications where you need to inject or absorb a precise DC current into a node — think laser diode bias, VCO tuning, or sensor offset nulling.

The surface-mount 8-uMAX/uSOP package is suitable for reflow soldering in standard PCB assembly lines.

It is ROHS3 compliant.

Frequently asked questions

What is the resolution of DS4432U+T&R?

The DS4432U+T&R is a 7-bit DAC, giving 128 discrete output current levels per channel.

What is the output type of DS4432U?

The output is current, unbuffered, and the architecture supports both current sink and current source modes.

How do I use DS4432U+T&R with a microcontroller?

Connect the SDA and SCL pins to the microcontroller's I2C bus. Set the slave address via the AD0 and AD1 pins (up to four devices per bus). Write a 7-bit code to the DAC register; the output current will sink or source accordingly. The supply range (2.7V to 5.5V) is compatible with 3.3V and 5V logic levels.
