ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability.
Supply Voltage (V
DD to VSS)........................-0.3V, +5V
Operating Temperature.......................-40˚C to +85˚C
Storage Temperature........................-65˚C to +150˚C
Power Dissipation Per Package
8-pin MSOP
(derate 4.85mW/OC above +70OC).........................400mW
SPECIFICATIONS
V
DD = +2.7V to +3.3V, LCOIL = 820µH/14Ω, ROSC = 714kΩ, EL Lamp Load = (8nF + 2.5kΩ)/1MΩ, and TAMB = -40
OC to +85OC. T
AMB = 25
OC for typical
values unless otherwise noted.
NOTE 1: Audible Noise is measured inside an acoustic sound chamber. The Sound Level Meter is a B&K
Mediator 2238, A-weighted with Condenser Mic type 4188 positioned 1/4 inch above the lamp in an 8 cubic inch
volume. See Figure 5 on page 6.
