TPA6020A2 - Texas Instruments

TPA6020A2 2.8-W STEREO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER

The TPA6020A2 is a 2.8-W stereo bridge-tied load (BTL) amplifier designed to drive stereo speakers with at least 3-Ω 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 a.
