The UTC S486 features an externally controlled, low-power consumption stand by mode. The UTC S486 exhibit a low quiescent current of typically 1.8mA, allowing usage in portable applications. The unity-gain stable UTC S486 can be configured by external gain-setting resistors. „ FEATURES * Operating voltage range VCC=2V ~ 5.5V * Output power: - 102mW @5V into 16 Ω with 0.1% THD+N max (1kHz) * Stand by mode available * Low current consumption: 2.5mA max * Click and pop reduction circuitry * Unity-gain stable * Short circuit protected „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing S486L-S08-R S486G-S08-R SOP-8 Tape Reel S486L-S08-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel (2) S08: SOP-8 (3) G: Halogen Free, L: Lead Free

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. All voltage values are measur ed with respect to the ground pin. 3. Attention must be paid to continuous power dissipation (VDD x 300mA). Exposure of the IC to a short circuit for an extended time period is dramatically reducing product life expectancy. „ THERMAL DATA PARAMETER SYMBOL RATINGS UNIT Junction to Ambient θJA 175 ° С/W „ RECOMMENDED OPERATING CONDITIONS PARAMETER SYMBOL RATINGS UNIT Supply Voltage V CC 2 ~ 5.5 V ACTIVE 1.5 ≤VSTB≤VCC V Standby Voltage Input STANDBY VSTB GND≤VSTB≤0.4(Note) V Load Resistor R L ≥16 Ω RL = 16 ~ 100Ω 400 pF Load Capacitor RL > 100Ω CL 100 pF Junction to Ambient θJA 150 /W ℃ Note: The minimum current consumption (ISTB) is guaranteed at GND for the whole temperature range.
