G1579 Global Mixed-mode Technology Inc. Low Power Dual Operational Amplifiers Features General Description The G1579 consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. The input common mode range of the G1579 can be beyond the rails, and the G1579 are with rail-to-rails output voltage swing. The quiescent current is 2mA per amplifier. Wide Supply Operation Range +4.5V to +19.5V Input Common Voltage Range Beyond the Rails Rail-to-Rail Output Voltage Swing Low Input Offset Voltage 3mV (Typical) Wide Bandwidth (unit gain) 30MHz Low Quiescent Current: 2mA per Amplifier Large DC Voltage Gain 85dB (Typical) Slew-Rate 30V/µs Unit-Gain Stable The G1579 also feature fast slewing and settle-times, as well as high output drive capability of 300mA (source/sink).These features make these amplifiers ideal for use as reference buffers for TFT-LCD. Other applications include battery power, portable devices, and anywhere low power consumption is important. Applications Portable Equipment LCD-TV Equipment Battery-Powered Equipment ASIC Input or Output Amplifier Low Power/Low Voltage Applications The G1579 is housed in a MSOP-8 package.
