Part Details:

LM2904 Low power dual operational amplifier Features Internally frequency compensated Large DC voltage gain: 100 dB N Wide bandwidth (unity gain): 1.1 MHz DIP8 (temperature compensated) (Plastic package) Very low supply current/op (500 µA) essentially independent of supply voltage Low input bias current: 20 nA (temperature compensated) D Low input offset current: 2 nA SO-8 Input common-mode voltage range includes (Plastic micropackage) negative rail Differential input voltage range equal to the power supply voltage Large output voltage swing 0 V to (V + CC -1.5 V) P Description TSSOP8 (Thin shrink small outline package) This circuit consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically for automotive and industrial control system. It operates from a single power supply S over a wide range of voltages. The low power MiniSO-8 supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp Pin connections (top view) circuits which now can be more easily implemented in single power supply systems. For example, these circuits can be directly supplied from the standard +5 V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply. 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 a single power supply.
