One Volt SMARTMOS Rail–to–Rail
Dual Operational Amplifier
MC33502D, P
T = –40° to +105°C, Case 751, 626
A
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
(1.0Vandground), yetcanoperatewithasupplyofupto7.0 V
and ground. Output current boosting techniques provide high
output current capability while keeping the drain current of the
amplifier to a minimum.
• Output Voltage Swings within 50 mV of Both Rails
• Input Voltage Range Includes Both Supply Rails
• High Voltage Gain: 100 dB
• No Phase Reversal on the Output for Over–Driven Input
Signals
• Input Offset Trimmed to <500 µV Typical
• Low Supply Current (I = 1.2 mA, Typical)
D
• 600 Ω Drive Capability
• Extended Operating Temperature Range (–40° to 105°C)
• Low Voltage, Single Supply Operation (1.0 V and Ground
to 7.0 V and Ground)
• High Input Impedance: Less than 40 fA Input Current
• Typical Unity Gain Bandwidth @ 5.0 V = 5.0 MHz,
@ 1.0 V = 4.0 MHz
