Three Programming Options to Best Meet Your Requirements
- I²C Programmable
Offering the highest functionality, integration, and flexibility, these devices allow adjustments "on the fly" or across multiple design platforms. EV kits and GUI software are available to assist with design and programming.
- Resistor/Capacitor Adjustable
These devices allow a high degree of flexibility at a low cost. Most key functions can be adjusted simply with external resistors or capacitors.
- Factory Fixed, Pin Selectable
Optimal when design parameters are known and minimizing board space/cost is paramount, these devices minimize the requirement for external components. Some devices offer pin-selectable functionality where the user gains flexibility by simply pulling pins high or low.
