Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters
specified in the Electrical Characteristics section is not recommended.
NOTES:
(1) Tested according to JEDEC standard JESD22-A114-B.
(2) Calculated from package in still air, mounted to 3 x 4.5in, 4-layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.
Electrical Characteristics
Unless noted otherwise, TA = 25°C for typical, -40°C < TA = TJ < 85°C for min and max. VCC = 5V, RISET = 25.5KΩ, RFSET = 100KΩ.
