产品简介
These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply ov-er a wide range of voltages.Operation from split supplies is also possible when the difference between the two supplies is 3 V to 30 V (for the LM2902and LM2902Q, 3 V to 26 V) and VCC is at least 1.5 V more positive than the input common-mode voltage.The low supply current drain is independent of the magnitude of the supply voltage.
