13 / 86 page ![]() Pinout STw5098 12/85 F8 AI 1CAPLINEIN A capacitor must be connected between CAPLINEIN and ground F9 AI 1MICRP Left and right channel differential pins for microphone input F10 AI 1AUX3R Left and right channel single ended pins for microphone or line input F11 AI 2MICRP Left and right channel differential pins for microphone input G1 AI 1AUX2LN Left and right channel differential pins for microphone or line input G2 AI 2AUX2LN Left and right channel differential pins for microphone or line input G3 AI 1LINEINL Left and right channel single ended pins for line input G4 AI 2LINEINL Left and right channel single ended pins for line input G8 P GNDA Ground pin for the analog section G9 AI 1AUX2RP Left and right channel differential pins for microphone or line input. G10 AI 1AUX2RN Left and right channel differential pins for microphone or line input G11 AI 2AUX2RN Left and right channel differential pins for microphone or line input H1 AI 1AUX2LP Left and right channel differential pins for microphone or line input H2 AI 2AUX2LP Left and right channel differential pins for microphone or line input H3 AO 2OLN 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. H4 P GNDCM Ground pin for analog reference. GNDCM can be connected to GNDA H5 AO 1EARPS 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. H6 AO 1EARP 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. Can deliver from 500mW to 125mW. H7 P VCCP Power supply pin for the left and right output drivers (headphones and line-out). Operating range: from VCCA to 3.3V H8 AO 1HPR 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. H9 AO 2ORN 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. H10 AI 2LINEINR Left and right channel single ended pins for line input H11 AI 2AUX2RP Left and right channel differential pins for microphone or line input J1 AO 1OLN 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. Table 1. STw5098 pin description Position Type Pin name Description |
