description
Quality, low-cost, bipolar fabrication with innovative design concepts are 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
(VCC–). With a Darlington transistor input stage, this device exhibits high input resistance, low input offset
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.
The TL3472C is characterized for operation from 0°C to 70°C. The TL3472I is characterized for operation from
–40°C to 105°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC–.
2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive input current can flow when the input
is less than VCC– – 0.3 V.
3. The output can be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.
4. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability.
5. The package thermal impedance is calculated in accordance with JESD 51.
