The LT
®
1886 is a 200mA minimum output current dual op
amp with outstanding distortion performance. The ampli-
fiers are gain-of-ten stable, but can be easily compensated
for lower gains. The LT1886 features balanced, high
impedance inputs with 4µA maximum input bias current,
and 4mV maximum input offset voltage. Single supply
applications are easy to implement and have lower total
noise than current feedback amplifier implementations.
The output drives a 25Ω load to
±4.3V
with
±6V
supplies.
On
±2.5V
supplies the output swings
±1.5V
with a 100Ω
load. The amplifier is stable with a 1000pF capacitive
load which makes it useful in buffer and cable driver
applications.
The LT1886 is manufactured on Linear Technology’s
advanced low voltage complementary bipolar process and
is available in a thermally enhanced SO-8 package.

Driving LCD with FPGA
I'm working on a project about FPGA recently, but I don't have any idea how to drive a 1602 LCD. Has anyone done this before? Can you give me some ideas or some guidance? Thank you very much! !...
