6 / 20 page  Tri p ath Techn o l o g y, I n c. - Techn i cal I n fo rmati o n 6 TAA4100A – KL/ Rev. 1.0/11.05 Pin Description PIN NAME /FUNCTION TYPE DESCRIPTION 1 IN1 INPUT Channel 1 Input 2 IN2 INPUT Channel 2 Input 3 IN3 INPUT Channel 3 Input 4 IN4 INPUT Channel 4 Input 5 BIASCAP Internal reference bypass capacitor connection 6 SLEEPB INPUT (L) Logic input, ACTIVE LOW. Setting SLEEP to low puts the TAA4100A in sleep mode. This pin must be driven high via an external power supply or microcontroller for the TAA4100A to begin operation. Input range is 0 to 5V with 3.3V compliant inputs. 7 AM INPUT (L) Logic input, ACTIVE HIGH. Enables Analog Mode operation. Typically driven by an external power supply of microcontroller. Input range is 0 to 5V with 3.3V compliant inputs. 8 OVRLDB OUTPUT (L) Logic output, ACTIVE LOW. OVRLDB low indicates the input has overloaded the amplifier 9 MUTEB INPUT (L) Logic Input, ACTIVE LOW. Setting MUTE to low puts the device in mute mode. Typically driven by external power supply or microcontroller. Input range is 0 to 5V with 3.3V compliant inputs. 10 AGND1 GND Analog ground 11 5VGEN On chip 5V regulator bypass capacitor connection 12 HMUTEB OUTPUT (L) Logic output, ACTIVE LOW. HMUTEB low indicates TAA4100A is in mute mode 13 VPPA POWER Positive power supply voltage connection 14 AGND2 GND Analog ground 15 CPUMP OUTPUT Charge pump output capacitor 16 OUT4P OUTPUT Positive Output Channel 4 17 VPP4 POWER Positive Supply Voltage Channel 4 18 PGND GND Power Ground 19 OUT4N OUTPUT Negative Output Channel 4 20 OUT3N OUTPUT Negative Output Channel 3 21 VPP3 POWER Positive Supply Voltage Channel 3 22 OUT3P OUTPUT Positive Output Channel 3 23 FAULT OUTPUT (L) Open Drain Logic Output, ACTIVE HIGH. FAULT high indicates fault condition. 24 OUT2P OUTPUT Positive Output Channel 2 25 VPP2 POWER Positive Supply Voltage Channel 2 26 OUT2N OUTPUT Negative Output Channel 2 27 OUT1N OUTPUT Negative Output Channel 1 28 PGND GND Power Ground 29 VPP1 POWER Positive Supply Voltage Channel 1 30 OUT1P OUTPUT Positive Output Channel 1 31 DCAP OUTPUT External Charge Pump Circuit Output. DCAP is a free running 400kHz square wave between VDDA (pin 13) and AGND (pin 14) with a 14.4Vpp nominal amplitude. 32 PGND GND Power Ground |
