FEATURES
1
•2 Available with Radiation Specification
– High Dose Rate 100 krad(Si)
– ELDRS Free 100 krad(Si)
• Internally Frequency Compensated for Unity
Gain
• Large DC Voltage Gain: 100 dB
• Wide Bandwidth (Unity Gain): 1 MH
z(Temperature Compensated)
• Wide Power Supply Range:
– Single Supply: 3V to 32V
– Or Dual Supplies: ±1.5V to ±16V
• Very Low Supply Current Drain (500 μA) −
Essentially Independent of Supply Voltage
• Low Input Offset Voltage: 2 mV
• Input Common-mode Voltage Range Includes
Ground
• Differential Input Voltage Range Equal to the
Power Supply Voltage
• Large Output Voltage Swing: 0V to V⁺ − 1.5V
UNIQUE CHARACTERISTICS
• In the Linear Mode the Input Common-Mode
Voltage Range Includes Ground and the Output
Voltage can also Swing to Ground, even though
Operated from only a Single Power Supply
Voltage.
• The Unity Gain Cross Frequency is Temperature
Compensated.
• The Input Bias Current is also Temperature
Compensated.
ADVANTAGES
• Two Internally Compensated Op Amps
• Eliminates Need for Dual Supplies
• Allows Direct Sensing Near Gnd and V_O also
Goes to Gnd
• Compatible with all Forms of Logic
• Power Drain Suitable for Battery Operation
DESCRIPTION
The LM158 series consists of two independent, high
gain, internally frequency compensated operational
amplifiers which were designed specifically to operate
from a single power supply over a wide range of
voltages. Operation from split power supplies is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
Application areas include transducer amplifiers, dc
gain blocks and all the conventional op amp circuits
which now can be more easily implemented in single
power supply systems. For example, the LM158
series can be directly operated off of the standard
+5V power supply voltage which is used in digital
systems and will easily provide the required interface
electronics without requiring the additional ±15V
power supplies.
