- Several test circuits
- Various ac/dc input signals
- PC control via a separately purchased system development platform (SDP)
- PC control software
- 12 extra bytes in EEMEM for user-defined information
- Resistor tolerance error stored in EEMEM
With versatile programmability, the AD5254 allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting read-back, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table.
The AD5254 supports a dual-supply ±2.25 V to ±2.75 V operation and a single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications. In addition, the AD5254 uses a versatile I2C serial interface that operates in fast mode, allowing speeds of up to 400 kbps and supporting the selection of up to four different I2C addresses.
The EVAL-AD5254SDZ can operate in single-supply and dual-supply mode and incorporates an internal power supply from the USB.
