TDA7491MV
25 W mono BTL class-D audio amplifier
Datasheet - production data
Description
The TDA7491MV is a mono BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Thanks to the high efficiency and an exposed-pad-down (EPD) package no heatsink is required. PowerSSO-36 with exposed pad down Furthermore, the filterless operation allows a reduction in the external component count. The TDA7491MV is pin to pin compatible with the TDA7491P, TDA7491LP and TDA7491HV for the left channel.

TPS74401数据手册

TPS74401数据手册

A precision reference and error amplifier deliver 1% accuracy over load, line, temperature, and process. Each LDO is stable with low-cost ceramic output capacitors and the device family is fully specified from –40°C to +125°C. The TPS744xx is offered in a small (5mm × 5mm) QFN package, yielding a highly compact total solution size. For applications that require additional power dissipation, the DDPAK (KTW) package is also available.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
