Connect to PV1. C2 BstSD Regulator active low shutdown C3 GND Ground C4 Gain0 Gain setting input 0 C5 PV1 Amplifier H-bridge power supply. Connect to V1. D1 AmpSD Amplifier active low shutdown D2 OUTR+ Non-inverting right channel output D3 NC No connect D4 OUTL+ Non-inverting left channel output D5 Gain1 Gain setting input 1 E1 VLimit Set to control output clipping level E2 OUTR- Inverting right channel output E3 PGND Power ground E4 OUTL- Inverting left channel output E5 NC No connect These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) Supply Voltage (VDD, V1) 6V Storage Temperature −65°C to +150°C Input Voltage −0.3V to VDD + 0.3V Power Dissipation (3) Internally limited ESD Susceptibility (4) 2000V ESD Susceptibility (5) 200V Junction Temperature 150°C Thermal Resistance θJA (YZR0025AAA) 40.5 °C/W (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum allowable power dissipation is PDMAX = (TJMAX − TA) / θJA or the given in Absolute Maximum Ratings, whichever is lower. (4) Human body model, 100pF discharged through a 1.5k Ω resistor. (5) Machine Model, 220pF–240pF discharged through all pins. Copyright © 2008–2013, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: LM48520 LM48520TLBD |
