LM359

Dual, High Speed, Programmable, Current Mode (Norton)

Amplifiers

General Description

Features

n User programmable gain bandwidth product, slew rate,

input bias current, output stage biasing current and total

device power dissipation

The LM359 consists of two current differencing (Norton) in-

put amplifiers. Design emphasis has been placed on obtain-

ing high frequency performance and providing user program-

mable amplifier operating 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. Pins for additional external frequency

compensation are provided. The amplifiers are designed to

operate from a single supply and can accommodate input

common-mode voltages greater than the supply.

n High gain bandwidth product (I_SET0.5 mA)

400 MHz for A_V10 to 100

30 MHz for A_V

n High slew rate (I_SET0.5 mA)

60 V/µs for A_V10 to 100

30 V/µs for A_V

n Current differencing inputs allow high common-mode

input voltages

Applications

n General purpose video amplifiers

n High frequency, high Q active filters

n Photo-diode amplifiers

n Operates from a single 5V to 22V supply

n Large inverting amplifier output swing, 2 mV to V_CC

−

for f 1 kHz

n Low spot noise,

n Wide frequency range waveform generation circuits

n All LM3900 AC applications work to much higher

frequencies
