Quadruple Operational Amplifiers

Description

l These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies is also possible when the difference between the two supplies is 3V to 30V (for the LM2902 and LM2902Q, 3V to 26V) and Vcc is at least 1.5V more positive than the input common-mode voltage.The low supply current drain is independent of the magnitude of the supply voltage.

Features

l Wide Range of Supply Voltages: Single Supply…3V to 30V  (LM2902 and LM2902Q 3V to 26V), or Dual Supplies

l Low Supply Current Drain Independent of Supply Voltage …0.8mATyp

l Common-Mode Input Voltage Range Includes Ground Allowing Direct Sensing Near Ground

l Low Input Bias and Offset Parameters:

          Input Offset Voltage … 3mV Typ

          A Versions… 2 mV Typ

          Input Offset Current … 2nATyp

          Input Bias Current … 20nATyp

          A Versions … 15nATyp

l Differential Input Voltage Range Equal to

          Maximum-Rated Supply Voltage… 32V

          (26V for LM2902 and LM2902Q)

l Open-Loop Differential Voltage

           Amplification … 100V/mV Typ

l Internal Frequency Compensation

Application

l Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational amplifier circuits that now can be more easily implemented in single-supply-voltage systems. For example, the LM124 can be operated directly from the standard 5-V supply that is used in digital systems and easily provides the required interface electronics without requiring additional ±15-V supplies.
