7 / 15 page Automotive DirectDrive Headphone Amplifiers with Output Protection and Diagnostics _______________________________________________________________________________________ 7 Pin Description Typical Operating Characteristics (continued) (VDD = VCPVDD = 5V, VSGND = VPGND = 0V, C1 = C2 = 1µF, RL = ∞, gain = -1.5V/V, THD+N measurement bandwidth = 22Hz to 22kHz, TA = +25°C, unless otherwise noted.) PIN NAME FUNCTION 1 INL Inverting Left-Channel Audio Input 2, 4 SGND Amplifier Signal Ground. The noninverting inputs of the amplifiers are connected to the amplifier signal ground. Connect both to the signal ground plane. 3 INR Inverting Right-Channel Audio Input 5VDD Amplifier Positive-Power Supply. Connect to positive supply. Bypass with a 1µF capacitor to SGND as close to the pin as possible. 6 SHDN Active-Low Shutdown Input 7 CPVDD Charge-Pump Power Supply. Powers charge-pump inverter, charge-pump logic, and oscillator. Connect to positive supply. Bypass with a 1µF capacitor to PGND as close to the pin as possible. 8 C1P Flying-Capacitor Positive Terminal. Connect a 1µF capacitor between C1P and C1N. 9, 15 PGND Power Ground. Connect both to the power ground plane. 10 C1N Flying-Capacitor Negative Terminal. Connect a 1µF capacitor between C1P and C1N. 11 CPVSS Charge-Pump Output. Connect to VSS and bypass with a 1µF capacitor to PGND. 12 DIAG Diagnostic Voltage Output 13 OUTR Right-Channel Output 14 VSS Amplifier Negative Power Supply. Connect to CPVSS. 16 OUTL Left-Channel Output ENTERING SHUTDOWN TRANSIENT MAX13330/31 toc27 200 μs/div VOUTL 1V/div VOUTR 1V/div VSHDN 5V/div POWER-UP/-DOWN TRANSIENT MAX13330/31 toc28 10ms/div VOUTL 1V/div VOUTR 1V/div VSHDN 5V/div |
