LM4952TS Description

Short technical summary and product information.

The LM4952TS from Texas Instruments is a dual audio power amplifier, suitable for applications requiring high output power and minimal component count. It operates with a power stage supply voltage ranging from 9.6V to 16V and can deliver 3.1 watts per channel into a 4Ω single-ended load with less than 1% THD+N when powered by a 12V DC supply. A typical output power of 3.8W is achievable under specific conditions.

This Class-AB amplifier features an analog input and a hardware control interface. It includes internal DC-controlled volume control, eliminating the need for external feedback resistors and allowing for easy gain adjustment. The device also incorporates pop and click circuitry to prevent noise during power transitions and a low-power, active-low shutdown mode.

The LM4952TS is housed in a TO-263 (KTW) package, measuring 10.16 mm x 14.35 mm. Its design minimizes external components, making it ideal for space-constrained display applications like flat panel monitors and TVs. The amplifier operates within an ambient temperature range of -40°C to 85°C.
