The DS4422N+T&R from Analog Devices is a versatile 7-bit current digital-to-analog converter (DAC) designed for applications requiring precise current control. This device integrates two independent current DAC channels, each capable of both sinking and sourcing current up to 200μA. The output current is programmable in 127 steps for both sink and source modes, offering fine-grained control.
Key electrical specifications include a wide operating voltage range of 2.7V to 5.5V and an operating temperature range of -40°C to +85°C. Communication with the DS4422N+T&R is handled via an I2C-compatible serial interface, allowing for easy integration into embedded systems. The device supports full-scale current settings determined by external resistors, with values typically ranging from 40kΩ to 160kΩ.
Packaged in a compact 14-TDFN (3x3mm) surface-mount package, the DS4422N+T&R is suitable for space-constrained designs. Its architecture supports current sink and source operations, making it ideal for applications such as power-supply adjustment, power-supply margining, and adjustable current loads. The device powers up in a high-impedance state, providing flexibility during system initialization.
