LM359 Description

Short technical summary and product information.

The LM359 is a dual, high-speed, programmable current-mode (Norton) amplifier from Texas Instruments, designed for high-frequency performance and user-programmable characteristics. Each amplifier is broadbanded to provide a high gain bandwidth product, fast slew rate, and stable operation for an inverting closed-loop gain of 10 or greater.

Key electrical specifications include a user-programmable gain bandwidth product of up to 400 MHz (at ISET = 0.5 mA, AV = 10 to 100) and a high slew rate of 60 V/µs (at ISET = 0.5 mA, AV = 10 to 100). It operates from a single supply voltage ranging from 5V to 22V. The device also features current differencing inputs that allow for high common-mode input voltages and a large inverting amplifier output swing from 2 mV to VCC - 2V.

Applications for the LM359 include general-purpose video amplifiers, high-frequency active filters, photo-diode amplifiers, and waveform generation circuits. It is available in PDIP and SOIC packages.

The LM359 is designed to operate from a single supply and can accommodate input common-mode voltages greater than the supply. Pins for additional external frequency compensation are provided.
