The LM124/SA534/LM2902 series consists of four independent, high-gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. The unique features include an input common-mode voltage range that includes ground and an output voltage that can swing to ground, even though operated from only a single power supply voltage. The unity gain crossover frequency and the input bias current are temperature-compensated.
The document provides specifications for a family of low‑power quad operational amplifiers from Philips Semiconductors. It describes the devices' internal frequency compensation, high DC gain, wide bandwidth, low supply current, and input/output voltage ranges.
Key sections include a description of unique features, absolute maximum ratings, DC electrical characteristics, typical performance curves, pin configurations, equivalent circuit diagrams, and example application circuits.
