The AD5282BRU200 is an IC component manufactured by Analog Devices Inc. It is a dual-channel, digitally controlled, nonvolatile resistor that features 8-bit resolution. The device operates with a power supply voltage ranging from 2.7V to 5.5V and comes in a 16-lead, 3 mm × 3 mm LFCSP package.
One of the key features of the AD5282BRU200 is its ability to provide an accurate resistance value digitally. It contains an integrated EEPROM which stores the resistor settings, making it nonvolatile. The resistor value can be easily programmed through an I2C-compatible digital interface.
The device has two independent channels, each equipped with a programmable resistor. These resistors can be set to either a fixed resistance value or adjusted using the onboard digital logic. The digital control allows for fine-tuning the resistance, ensuring precise voltage or current control in various applications.
To ensure the accuracy of resistance settings, the AD5282BRU200 implements an internal feedback resistor that reduces nonlinearity and temperature coefficient errors. This enables stable and reliable performance across a wide temperature range.
The IC component also includes a shutdown mode, which allows the device to reduce power consumption when not in use. This feature is particularly useful in battery-powered applications, where power efficiency is critical.
Furthermore, the AD5282BRU200 offers a high reliability by incorporating resistance tolerance and temperature coefficients that meet stringent industry standards
