Advance Information
One Volt SMARTMOS™
Rail-to-Rail Dual
Operational Amplifier
The MC33502 operational amplifier provides rail–to–rail operation on both
the input and output. The output can swing within 50 mV of each rail. This
rail–to–rail operation enables the user to make full use of the entire supply
voltage range available. It is designed to work at very low supply voltages
(1.0 V and ground), yet can operate with a supply of up to 7.0 V and ground.
Output current boosting techniques provide high output current capability
while keeping the drain current of the amplifier to a minimum.
• Low Voltage, Single Supply Operation (1.0 V and Ground to
7.0 V and Ground)
• High Input Impedance: Typically 40 fA Input Current
• Typical Unity Gain Bandwidth @ 5.0 V = 5.0 MHz, @ 1.0 V = 4.0 MHz
• High Output Current (ISC = 50 mA @ 5.0 V, 10 mA @ 1.0 V)
• Output Voltage Swings within 50 mV of Both Rails @ 1.0 V
• Input Voltage Range Includes Both Supply Rails
• High Voltage Gain: 100 dB Typical @ 1.0 V
• No Phase Reversal on the Output for Over–Driven Input Signals
• Input Offset Trimmed to 0.5 mV Typical
• Low Supply Current (ID = 1.2 mA/per Amplifier, Typical)
• 600 Ω Drive Capability
• Extended Operating Temperature Range (–40 to 105°C)
APPLICATIONS
• Single Cell NiCd/Ni MH Powered Systems
• Interface to DSP
• Portable Communication Devices
• Low Voltage Active Filters
• Telephone Circuits
• Instrumentation Amplifiers
• Audio Applications
• Power Supply Monitor and Control
• Compatible with VCX Logic
