Setting SLEEP to low puts the TA2041A in sleep mode. This pin must be driven high via an external power supply or microcontroller for the TA2041A 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 TA2041A is in mute mode 13 VPPA POWER Positive power supply voltage connection 14 AGND2 GND Analog ground 15 CPUMP Charge pump output capacitor 16 OUT4P OUTPUT Positive Output Channel 4 17 VPP4 POWER Positive Supply Voltage Channel 4 18 PGND34 GND Power Ground for Outputs 3 and 4 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 PGND12 GND Power Ground for Outputs 1 and 2 29 VPP1 POWER Positive Supply Voltage Channel 1 30 OUT1P OUTPUT Positive Output Channel 1 31 DCAP2 OUTPUT Charge pump switching capacitor connection. DCAP2 is a free running 400kHz square wave between VDDA (pin 13) and AGND (pin 14) with a 14.4Vpp nominal amplitude. 32 DCAP1 INPUT Charge pump switching capacitor connection. DCAP1 is level shifted 10 volts above DCAP2 with the same amplitude, frequency, and phase as DCAP2. |
