description/ordering information
NC − No internal connection
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), and V is at least 1.5 V more positive than the
CC
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.
