14 / 85 page  Pinout STw5098 14/85 K8 AO 1EARNS EARPS, EARNS (sense) pins must be connected on the application board to EARP, EARN pins respectively. The connection must be as close as possible to the pins. K9 P VCCLS Power supply pins for the mono differential output driver. Operating range: from VCCA to 5.5V K10 AO 1ORP 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. K11 P GNDP Ground pin for the left, right and mono-differential output drivers. GNDP and GNDA must be connected together. L1 P VCCP Power supply pin for the left and right output drivers (headphones and line-out). Operating range: from VCCA to 3.3V L2 P GNDP Ground pin for the left, right and mono-differential output drivers. GNDP and GNDA must be connected together. L3 AO 1VCMHPS VCMHPS (sense) pin must be connected on the application board to VCMHP pin. The connection must be as close as possible to the pins. L4 AO 2VCMHP Common mode voltage headphones output. The negative pins of headphones left and right speakers can be connected to this pin to avoid decoupling capacitors. L5 AO 2LSPS LSPS, LSNS (sense) pins must be connected on the application board to LSP, LSN pins respectively. The connection must be as close as possible to the pins. L6 AO 2LSP 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 of 8 Ω.; It can deliver up to 500mW. L7 AI 2CAPLS A capacitor can be connected between this node and ground L8 AO 2LSN 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 of 8 Ω. Can deliver up to 500mW. L9 AO 2LSNS LSPS, LSNS (sense) pins must be connected on the application board to LSP, LSN pins respectively. The connection must be as close as possible to the pins. L10 P VCCP Power supply pin for the left and right output drivers (headphones and line-out). Operating range: from VCCA to 3.3V L11 AO 2HPR 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. Table 1. STw5098 pin description Position Type Pin name Description |
