The LF353DR is a dual JFET Operational Amplifier (Op Amp) manufactured by Texas Instruments. It has two independent, high-gain, 2-input, internally compensated op-amps. It is designed specifically for audio applications and features a very low-noise input stage (15nV/v Hz) and a high output current of up to 350mA. It is capable of both inverting and non-inverting operations and has excellent common mode rejection ratio (CMRR) over a wide range of input frequencies. In addition, it is specified for operation over a wide supply voltage range (± 3V to ± 20V). It has low power consumption and is designed to be used with a smaller associated external heat sink. This device can be used for a wide variety of applications, including active filters, comparators, voltage followers, and regulators.
