Analog Devices Inc. AD514x Eval Boards
Analog Devices AD514x Eval Boards allow multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table.
The AD514x supports dual-supply ±2.25V to ±2.75V operation and single-supply 2.3V to 5.5V operation, making the device ideal for battery-powered and many other applications.
The EVAL-AD5141x can be configured as a versatile I2C or SPI serial interface. The EVAL-AD5142x uses a versatile SPI-compatible serial interface, allowing speeds up to 50MHz. The EVAL-AD5142Ax utilizes a versatile I2C-compatible serial interface that operates in fast mode, supporting speeds of up to 400kbps and enabling a selection of up to nine I2C addresses. The EVAL-AD5143x can be configured as a versatile I2C or SPI serial interface.
The Analog Devices AD514x Eval Boards can operate in single-supply or dual-supply mode and contain an internal power supply from the USB.
