General Description
The G1544 consists of four independent, high gain,
internally frequency compensated operational amplifi-
ers 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 G1544 can be beyond the
rails, and the G1544 are with rail-to-rails output volt-
age swing. The quiescent current is 500µA per ampli-
fier.
The G1544 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.
The G1544 is housed in a 10-pin MSOP packages.
