Design Notes
For optimal performance, place decoupling capacitors (100 pF and 0.1 Β΅F) as close as possible to the VCC pins. Use a solid ground plane and ensure the exposed pad is soldered to the ground for thermal and electrical connectivity. Keep input and output traces short and matched to maintain signal integrity.
The ADL5561ACPZ-R7 dissipates up to 144 mW at 3.6 V and 40 mA. The LFCSP package has a thermal resistance of approximately 40Β°C/W. Ensure adequate copper area on the PCB to keep the junction temperature below 125Β°C. In high-temperature environments, consider adding thermal vias.
Avoid driving the inputs beyond the specified common-mode range. Use proper termination for single-ended inputs to prevent reflections. Do not leave gain-select pins floating; tie them to VCC or GND as needed. Ensure the supply voltage is within 3 V to 3.6 V to avoid damage.
