The TPD2125 is a high-speed dual complimentary MOSFET driver. The TPD2125 converts CMOS or TTL

inputs to gate signals suitable for driving a complimentary pair of MOSFETs in a dual half-bridge or single

full-bridge configuration. When three TPD2125’s are mated with a TCD6000, the chipset is a six-channel,

digital input, 75W (8Ω) per channel Amplifier. This stereo mosfet driver, when paired with a Class T

controller, offers both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
