13 / 85 page  STw5098 Pinout 13/85 J2 AO 1OLP Audio differential line out amplifier for left and right channels. This outputs can drive up to 1k Ω resistive load. Can be used as single ended output. J3 AO 2OLP Audio differential line out amplifier for left and right channels. This outputs can drive up to 1k Ω resistive load. Can be used as single ended output. J4 AO 2HPL Audio single ended headphones amplifier outputs for left and right channels. The outputs can drive 50nF (with series resistor) or directly an earpiece transductor of 16 Ω. J5 AO 1VCMHP Common mode voltage headphones output. The negative pins of headphones left and right speakers can be connected to this pin to avoid decoupling capacitors. J6 AI 1CAPEAR A capacitor can be connected between this node and ground J7 AO 1EARN Analog differential loudspeaker amplifier output for Left channel or Right channel or the sum of both. This output can drive 50nF (with series resistor) or directly an earpiece transductor from 8 Ω to 32Ω.; It can deliver from 500mW to 125mW. J8 P VCCLS Power supply pin for the mono differential output driver. Operating range: from VCCA to 5.5V J9 AO 2ORP Audio differential line out amplifier for left and right channels. This outputs can drive up to 1k Ω resistive load. Can be used as single ended output. J10 AO 1ORN Audio differential line out amplifier for left and right channels. This outputs can drive up to 1k Ω resistive load. Can be used as single ended output. J11 AI 1LINEINR Left and right channel single ended pins for line input K1 P GNDCM Ground pin for analog reference. GNDCM can be connected to GNDA K2 P VCCP Power supply pins for the left and right output drivers (headphones and line-out). Operating range: from VCCA to 3.3V K3 AO 1HPL Audio single ended headphones amplifier outputs for left and right channels. The outputs can drive 50nF (with series resistor) or directly an earpiece transductor of 16 Ω. K4 AO 2VCMHPS VCMHPS (sense) pin must be connected on the application board to VCMHP pin. The connection must be as close as possible to the pins. K5 P VCCLS Power supply pin for the mono differential output driver. Operating range: from VCCA to 5.5V K6 P GNDP Ground pin for the left, right and mono-differential output drivers. GNDP and GNDA must be connected together. K7 P GNDP Ground pin for the left, right and mono-differential output drivers. GNDP and GNDA must be connected together. Table 1. STw5098 pin description Position Type Pin name Description |
