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
• High Output Current (70 mA typically)
• 600 Ω Drive Capability
• Standard Pinouts; No Additional Pins or Components Required
• 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
(P and D Suffixes)
