Quality, low-cost, fabrication with remarkable design concepts is employed for the TL3472-Q1 operational amplifier. This device offers 4.5MHz of gain-bandwidth product, and fast settling time. Although the TL3472-Q1 can be operated from split supplies, TL3472-Q1 is particularly suited for single-supply operation because the common-mode input voltage range includes ground potential (VCC–). This device exhibits high input resistance, low input offset voltage, and high gain. This low-cost amplifier is an alternative to the MC33072 and the MC34072 operational amplifiers.
