INTERNALLY FREQUENCY COMPENSATED LARGE DC VOLTAGE GAIN : 100dB WIDE BANDWIDTH (unity gain) : 1.1MHz (temperature compensated) VERY LOW SUPPLY CURRENT/AMPLI (500µA) - ESSENTIALLY INDEPENDENT OF SUPPLY VOLTAGE LOW INPUT BIAS CURRENT : 20nA (temperature compensated) LOW INPUT OFFSET CURRENT : 2nA INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND DIFFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE POWER SUPPLY VOLTAGE LARGE OUTPUT VOLTAGE SWING 0V TO (VCC ­ 1.5V) N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) ORDER CODES Part Number LM2904 Temperature Range ­40oC, +125oC Package · · 2904-01.TBL 2904-01.EPS N D DESCRIPTION This circuit consists of two independent, high gain, internally frequency compensated which were designed specifically to operate from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, dc gain blocks and all the conventionalop-amp circuits which now can be more easilyimplemented in single power supply systems. For example, these circuits canbe directly operatedoff the standard+ 5V power supply voltage 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 only a single power supply voltage. The gain-bandwidth product is temperature compensated.
