8.1 Overview
These devices consist of two independent, high-gain frequency-compensated operational amplifiers designed to
operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the
difference between the two supplies is 3 V to 32 V (3 V to 26 V for the LM2904 device), and VCC is at least 1.5 V
more positive than the input common-mode voltage. The low supply-current drain is independent of the
magnitude of the supply voltage.
Applications include transducer amplifiers, DC amplification blocks, and all the conventional operational amplifier
circuits that now can be implemented more easily in single-supply-voltage systems. For example, these devices
can be operated directly from the standard 5-V supply used in digital systems and easily can provide the required
interface electronics without additional ±5-V supplies.
