What the LF353 does
The LF353 is a wide-bandwidth, JFET-input dual operational amplifier designed for high-speed applications. It features a typical gain bandwidth of 3 MHz, a slew rate of 13 V/µs, and a low supply current of 3.6 mA per amplifier. With an input bias current of 50 pA and high input impedance of 10^12 Ω, this device supports circuits like high-speed integrators, digital-to-analog converters, and sample-and-hold circuits. It operates across commercial temperature ranges and is available in SOIC and PDIP packages for motor systems, audio mixers, and renewable energy inverters.
