The MC33304 is a monolithic bipolar operational amplifier. This low voltage rail–to–rail amplifier has both a rail–to–rail input and output stage, with high output current capability. This amplifier also employs SLEEPMODE technology. In sleepmode, the micropower amplifier is active and waiting for an input signal. When a signal is applied, causing the amplifier to source or sink ≥200 µA (typically) to the load, it will automatically switch to the awakemode (supplying up to 70 mA to the load). When the output current drops below 90 µA, the amplifier automatically returns to the sleepmode.

Excellent performance can be achieved as an audio amplifier. This is due to the amplifier’s low noise and low distortion. A delay circuit is incorporated to prevent crossover distortion.

• Ideal for Battery Applications

• Full Output Signal (No Distortion) for Battery Applications Down

to ±0.9 VDC.

• Single Supply Operation (+1.8 to +12 V)

• Rail–To–Rail Performance on Both the Input and Output

“Awakemode” (High Performance, ID = 1200 µA/Amp)

• Automatic Return to Sleepmode when Output Current Drops Below

Threshold, Allowing a Fully Functional Micropower Amplifier

• Independent Sleepmode Function for Each Amplifier

• No Phase Reversal on the Output for Overdriven Input Signals

• High Output Current (70 mA typically)

• 600 Ω Drive Capability

• Drop–In Replacement for Many Other Quad Operational Amplifiers

• Similar to MC33201, MC33202 and MC33204 Family

• The MC33304 Amplifier is Offered in the Plastic DIP or SOIC Package

NOTES: 1. The differential input voltage of each amplifier is limited by two internal diodes. The diodes are connected across the inputs in parallel and opposite to

each other. For more differential input voltage range, use current limiting resistors in series with the input pins.

2.The common–mode input voltage range of each amplifier is limited by diodes connected from the inputs to both power supply rails. Therefore, the voltage on either input must not exceed supply rail by more than ±500 mV.

3.Simultaneous short circuits of two or more amplifiers to the positive or negative rail can exceed the power dissipation ratings and cause eventual failure of the device.

4.Rail–to–rail performance is achieved at the input of the amplifier by using parallel NPN–PNP differential stages. When the inputs are near the negative rail (VEE < VCM < 800 mV), the PNP stage is on. When the inputs are above 800 mV (i.e. 800 mV < VCM < VCC), the NPN stage is on. This switching of the input pairs will cause a reversal of input bias current. Slight changes in the input offset voltage will be noted between the NPN and PNP pairs. Cross–coupling techniques have been used to keep this change to a minimum.

5.Power dissipation must be considered to ensure maximum junction (TJ) is not exceeded. (See Figure 2)

6.When connected as a voltage follower and used in transient conditions, a current limiting resistor may be needed between the output and the inverting input. This is because of the back to back diodes clamped across the inputs. The value of this resistor should be between 1.0 kΩ and 10 kΩ. If the amplifier does not become slew rate limited and is processing low frequency waveforms, then no resistor would be necessary. (The output could be tied directly to the negative input.)
