STMicroelectronics TS4962M Class D Audio Power Amplifier Datasheet
The TS4962M is a differential Class-D BTL (Bridge-Tied Load) power amplifier designed to drive up to 2.3W into a 4Ω load or 1.4W into an 8Ω load at a 5V supply voltage. It operates from a supply voltage range of 2.4V to 5.5V and achieves high efficiency, typically around 88%. The device includes features such as adjustable gain via external resistors, low pop & click noise circuitry for fast startup within 5ms, and an active-low standby function that reduces current consumption to approximately 10nA.
