description/ordering information
Quality, low-cost, bipolar fabrication with innovative design concepts is employed for the TL3472 operational
amplifier. This device offers 4 MHz of gain-bandwidth product, 13-V/µs slew rate, and fast settling time, without
the use of JFET device technology. Although the TL3472 can be operated from split supplies, it is particularly
suited for single-supply operation because the common-mode input voltage range includes ground potential
(V ). With a Darlington transistor input stage, this device exhibits high input resistance, low input offset
CC–
voltage, and high gain. The all-npn output stage, characterized by no dead-band crossover distortion and large
output voltage swing, provides high-capacitance drive capability, excellent phase and gain margins, low
open-loop high-frequency output impedance, and symmetrical source/sink ac frequency response. This
low-cost amplifier is an alternative to the MC33072 and the MC34072 operational amplifiers.
