G1540 Global Mixed-mode Technology Inc. Low Power Quadruple Operational Amplifiers Features General Description The G1540 consists of four 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 G1540 can be beyond the rails, and the G1540 are with rail-to-rails output voltage swing. The quiescent current is 500µA per amplifier. Wide Supply Operation Range +4.5V to +16V Input Common Voltage Range Beyond the Rails Rail-to-Rail Output Voltage Swing Low Input Offset Voltage 3mV (Typical) Wide Bandwidth (unit gain) 4MHz Low Quiescent Current: 500µA per Amplifier Large DC Voltage Gain 100dB (Typical) Slew-Rate 5.5V/us Unit-Gain Stable The G1540 also feature fast slewing and settle-times, as well as high output drive capability of 60mA (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 G1540 is housed in a 14-pin SOP, TSSOP and TQFN4X4-16 packages.
