The LM1837 is a dual autoreversing high gain tape pream plifier for applications requiring optimum noise performance. It has forward (left, right) and reverse (left, right) inputs which are selectable through a high impedance logic pin. It is an ideal choice for a tape playback amplifier when a com bination of low noise, autoreversing, good power supply re jection, and no power-up transients are desired. The appli cation also provides transient-free muting with a single pole grounding switch.
