november 2009 doc id 16486 rev 1 1/13 13 lm2902h low power quad operational amplifier features wide gain bandwidth: 1.3 mhz extended temperature range: -40c to +150c input common-mode voltage range includes negative rail large voltage gain: 100 db very low supply current: 0.7 ma low input bias current: 20 na low input offset current: 2 na wide power supply range: ? single supply: +3 v to +30 v ? dual supplies: 1.5 v to 15 v internal esd protection: ? 250 v hbm ? 150 v mm applications industrial automotive description this circuit consists of four independent, high-gain, internally frequency-compensated operational amplifiers, designed specifically for automotive and industrial control systems. it operates 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 conventional op-amp circuits, which can now be more easily implemented in single power supply systems. for example, the circuit can be directly supplied from a standard +5 v, which is used in logic systems, and will easily provide the required interface electronics without need for any additional power supply. in 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. d so-14 (plastic micropackage) shape of wafer
