General Description
The G1577 consists of one independent, high gain,
internally frequency compensated operational amplifi-
ers 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 G1577 can be beyond the
rails, and the G1577 is with rail-to-rails output voltage
swing. The quiescent current is 5.5mA, typically.
The G1577 also feature fast slewing and set-
tle-times, as well as high output drive capability of
1300mA (source/sink). 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 con-
sumption is important.
The G1577 is housed in a TDFN3X3-8 package.
