TDA7498E Datasheet 160-watt + 160-watt dual BTL class-D audio amplifier PowerSSO-36 exposed pad up Maturity status link TDA7498E Device summary Order code TDA7498ETR Operating temperature range 0 to 70 °C Package PowerSSO36 (EPU) Packing Tape and reel Features • 160-W + 160-W output power at THD = 10% with RL = 4 Ω and VCC = 36 V • 1 x 220 W output power mono parallel BTL at THD = 10% with RL = 3 Ω and VCC = 36 V • Wide-range single-supply operation (14 - 36 V) • High efficiency (η = 85%) • Parallel BTL function using the MODE pin • Four selectable, fixed gain settings of nominally 23.8 dB, 29.8 dB, 33.3 dB and 35.8 dB • Differential inputs minimize common-mode noise • Standby and mute features • Smart protection • Thermal overload protection • Small offset less than 20 mV Description The TDA7498E is a dual BTL class-D audio amplifier with a single power supply designed for home systems and active speaker applications. It comes in a 36-pin PowerSSO package with exposed pad up (EPU) to facilitate mounting a separate heatsink.
