Speaker Amplifier Switching Frequency Additional switching rates fSPK_AMP(1) - 8 - x fS when PWM_FREQ Pin = 1 available in Software Control Mode.) PVDD = 15 V, TA = 25 °C, Die - 120 - m Ω Only On Resistance of Output MOSFET (both RDS(ON) PVDD= 15V, TA = 25 °C, high-side and low-side) Includes: Die, Bond Wires, - 150 - m Ω Leadframe (1) The digital boost block contributes +6dB of gain to this value. The audio signal must be kept below -6dB to avoid clipping the digital audio path. Copyright © 2013, Texas Instruments Incorporated 7 Product Folder Links: TAS5760MD |
