4 / 36 page Absolute maximum ratings TS4999 4/36 Note: When the 3D effect is switched on, both channels must be in operation or in shutdown mode at the same time. Table 2. Operating conditions Symbol Parameter Value Unit VCC Supply voltage(1) 1. For VCC from 2.4 to 2.5 V, the operating temperature range is reduced to 0° C ≤Tamb ≤70° C 2.4 to 5.5 V Vin Input voltage range GND to VCC VSTBY Standby voltage input(2) Device ON Device OFF 2. Without any signal on VSTBY, the device will be in standby (internal 300 kΩ (+/-20 %) pull down resistor) 1.4 ≤VSTBY ≤VCC GND ≤VSTBY ≤0.4(3) 3. Minimum current consumption is obtained when VSTBY = GND V RL Load resistor ≥4 Ω VIH G0, G1, 3D, High Level Input Voltage(4) 4. Between G0, G1, 3D pins and GND, there is an internal 300 k Ω (+/-20 %) pull-down resistor. When pins are floating, the gain is 3.5 dB and 3D effect is off. In full standby (left and right channels OFF), these resistors are disconnected (HiZ input). 1.4 ≤VIH ≤VCC V VIL G0, G1, 3D, Low Level Input Voltage GND ≤VIL ≤0.4 V Rthja Thermal Resistance Junction to Ambient (5) 5.
