LM359
Dual, High Speed, Programmable, Current Mode (Norton)
Amplifiers
General Description
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.
Applications
n General purpose video amplifiers
n High frequency, high Q active filters
n Photo-diode amplifiers
n Wide frequency range waveform generation circuits
n All LM3900 AC applications work to much higher
frequencies
Features
n User programmable gain bandwidth product, slew rate,
input bias current, output stage biasing current and total
device power dissipation
n High gain bandwidth product (I_SET = 0.5 mA)
400 MHz for A_V = 10 to 100
30 MHz for A_V = 1
n High slew rate (I_SET = 0.5 mA)
60 V/µs for A_V = 10 to 100
30 V/µs for A_V = 1
n Current differencing inputs allow high common-mode
input voltages
n Operates from a single 5V to 22V supply
n Large inverting amplifier output swing, 2 mV to V_CC −
2V
n Low spot noise,
for f > 1 kHz
