Low power dual operational amplifier

Philips Semiconductors Linear Products Product specification Low power dual operational amplifier AU2904 DESCRIPTION The AU2904 consists of two independent, high-gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage.

The unity gain crossover frequency and the input bias current are temperature-compensated.

VO ≈ 1.4V, RS=0Ω with VCC from 5V to 30V and over full input common-mode range (0VDC+ to VCC-1.5V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+-1.5, but either or both inputs can go to +32V without damage. 4. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of coupling increases at higher frequencies. 5. Short-circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 40mA independent of the magnitude of V+. At values of supply voltage in excess of +15VDC, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction.
