1.0 V, Rail-to-Rail, Single
Operational Amplifiers
The MC33501/503 operational amplifier provides railtorail
operation on both the input and output. The output can swing within 50
mV of each rail. This railtorail 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 Bias Current
Typical Unity Gain Bandwidth @ 5.0 V = 4.0 MHz,
@ 1.0 V = 3.0 MHz
High Output Current (I
SC
= 40 mA @ 5.0 V, 13 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 OverDriven Input Signals
Input Offset Trimmed to 0.5 mV Typical
Low Supply Current (I
D
= 1.2 mA/per Amplifier, Typical)

W Drive Capability
Extended Operating Temperature Range (40 to 105
C)
