Low Voltage Rail-To-Rail Sleep-Mode Operational Amplifier

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 Sleep–Mode 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

• Output Voltages Swings Typically within 100 mV of Both Rails

(RL = 1.0 mΩ)

• Two States: “Sleepmode” (Micropower, ID = 110 µA/Amp) and

“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
