BooklyMicro JRC4558 Dual Operational Amplifier Features General Description • Power Supply Range: - Signal Supply : 3V to 20V - Dual Supply : ± 1.5V to ± 10V • Large DC Voltage Gain : 100dB • Large Output Swing : 0V ~ VDD- 1.5V • Bandwidth(unity gain) : 2MHz • Internally Frequency Compensated for Unity Gain • Low Input Offset Voltage : 1mV • Lead Free Available (RoHS Compliant) Applications • Amplifiers • Filters • Analog Circuit The JRC4558 consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply up to 20 volts. Operation from dual power supplies is also possible and the power supply current drain is essentially independent of the magnitude of the power [ ... ]
