The F4558 includes two independent, high-gain, internal frequency-compensated dual operational amplifiers, which are suitable for single-supply use with a wide range of supply voltages, and are also suitable for dual-supply operating modes. Under the recommended operating conditions, the supply current is equal to The supply voltage is irrelevant. It is used in sense amplifiers, DC gain blocks and all other applications where op amps can be operated from a single supply. […]


1. Internal frequency compensation
2. High DC voltage gain (about 100dB)
3. unity gain bandwidth (about 1MHz)
4. Low input bias current
5. Low input offset voltage and offset current
6. Wide common-mode input voltage range, including ground
7. Wide differential mode input voltage range, equal to the power supply voltage range
8. Large output voltage swing (0 to Vcc-1.5V)
