General Description
The G1540 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 G1540 can be beyond the
rails, and the G1540 are with rail-to-rails output volt-
age swing. The quiescent current is 500µA per ampli-
fier.
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.
The G1540 is housed in a 14-pin SOP, TSSOP and
TQFN4X4-16 packages.
