The TPA6020A2 is a 2.8-W stereo bridge-tied load (BTL) amplifier designed to drive stereo speakers with at least 3- impedance. The device operates from 2.5 V to 5.5 V, drawing only 8 mA of quiescent supply current. The feedback resistors are internal, allowing the gain to be set with only two input resistors per channel. The amplifier's fully differential architecture performs with -80 dB of power supply rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup time with minimal pop, making the TPA6020A2 ideal for notebook PC applications.
