The TS4962 is a differential class-D BTL power amplifier. It can drive up to 2.2 W into a 4 Ω load and 1.4 W into an 8 Ω load at 5 V. It achieves outstanding efficiency (88% typ.) compared to standard AB-class audio amps.
The TS4962 is a differential class-D BTL power amplifier designed for applications such as cellular phones, PDAs, and notebook PCs. It operates from a supply voltage of 2.4 V to 5.5 V and delivers up to 2.8 W into a 4 Ω load with 10% THD+N maximum at 5 V.
The device features an adjustable gain controlled via external resistors, low current consumption in standby mode (typical 10 nA), and thermal shutdown protection. It is available in a DFN8 3 x 3 mm package.

The device operates from a supply voltage of 2.4 V to 5.5 V.
The gain can be controlled via two external gain setting resistors.
The current consumption reduces to 10 nA typical when in standby mode.
