The MC3403 is a low-cost, quad operational amplifier with true differential inputs.
It has several advantages over standard operational amplifier types in single supply applications, including the ability to operate at supply voltages as low as 3.0 V or as high as 36 V with low quiescent currents.
The device also has a common mode input range that includes the negative supply, eliminating the need for external biasing components in many applications.
It features short circuit protected outputs, a class AB output stage for minimal crossover distortion, and internally compensated performance.
The device is available in Pb-Free packages and has industry standard pin-outs.
It is suitable for single supply operation from 3.0 V to 36 V, as well as split supply operation from ±1.5 V to ±18 V.
The device is also available in various package options for different shipping needs.
The electrical characteristics of the MC3403 are detailed in the data sheet, including input offset voltage, input offset current, large signal open loop voltage gain, input bias currents, output impedance, input impedance, output voltage range, and more.
The device is made using four internally compensated, two-stage operational amplifiers, and the output stage allows the output to swing to ground in single supply operation without exhibiting crossover distortion in split supply operation.
The device also has a unique input stage that allows the input common mode range to include the negative supply or ground in single supply operation without saturating the input devices or the differential to single-ended converter.
The device is suitable for various applications, including inverter pulse response, sine wave response, open loop frequency response, power bandwidth, output swing versus supply voltage, input bias current versus temperature, input bias current versus supply voltage, voltage reference, Wien bridge oscillator, high impedance differential amplifier, and comparator with hysteresis.
