These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. † Currents are positive into, negative out of the specified terminal. Consult Packaging Section of the Power Supply Control Data Book (TI Literature Number SLUD003) for thermal limitations and considerations of packages. electrical characteristics, TA = −40°C to 125°C for the UCC2808AQ-x, VDD = 10 V (see Note 6), 1-µF capacitor from VDD to GND, R = 22 k Ω, C = 330 pF TA = TJ, (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Oscillator Section Oscillator frequency 175 194 213 kHz Oscillator amplitude/VDD See Note 1 0.44 0.5 0.56 V/V NOTES: 1.
