G1584 Global Mixed-mode Technology Quadruple Rail-to-Rail Operational Amplifiers Features General Description The G1584 consists of one independent, high gain, internally frequency compensated operational amplifiers which was 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 G1584 can be beyond the rails, and the G1584 is with rail-to-rails output voltage swing. The quiescent current is 8.5mA, typically. Wide Supply Operation Range +4.5V to +20V Input Common Voltage Range Beyond the Rails Rail-to-Rail Output Voltage Swing High Peak Source Capability 1300mA High Peak Sink Capability 850mA Low Input Offset Voltage 3mV (Typical) Wide -3dB Bandwidth 35MHz Quiescent Current: 8.5mA Large DC Voltage Gain 80dB (Typical) Slew-Rate 50V/µs Unit-Gain Stable The G1584 also feature fast slewing and settle-times, as well as high output drive capability of source 1300mA /sink 850mA. These features make this amplifier 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 G1584 is housed in a TSSOP-14, TSSOP-14 (FD) and TQFN4X4-16 package.
