Philips Semiconductors Linear Products Product specification Low power dual operational amplifier DESCRIPTION AU2904 PIN CONFIGURATION 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. D and N Packages OUTPUT A 1 INVERTING INPUT A 2 A NON INV INPUT A 3 –+ V– 4 FEATURES 8 V+ B 7 OUTPUT B –+ – 6 INVERTING INPUT B 5 NON INV INPUT B • Internally frequency-compensated for unity gain • Large DC voltage gain: 100dB • Wide bandwidth (unity gain): 1MHz (temperature-compensated) • Wide power supply range Single supply: 3VDC to 30VDC or dual UNIQUE FEATURES • Very low supply current drain (400µA): essentially independent of 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. Top View supplies: ±1.5VDC to ±15VDC supply voltage (1mW/op amp at +5VDC) • Low input bias current: 45nADC (temperature-compensated) • Low input offset voltage: 2mVDC and offset current: 5nADC • Differential input voltage range equal to the power supply voltage • Large output voltage: 0VDC to V+-1.5VDC swing 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.
