The LT
®
1190 is a video operational amplifier optimized for
operation on
±5V,
and a single 5V supply. Unlike many
high speed amplifiers, this amplifier features high open-
loop gain, over 85dB, and the ability to drive heavy loads
to a full-power bandwidth of 20MHz at 7V
P-P
. In addition
to its very fast slew rate, the LT1190 features a unity-
gain-stable bandwidth of 50MHz and a 75° phase margin,
making it extremely easy to use.
Because the LT1190 is a true operational amplifier, it is an
ideal choice for wideband signal conditioning, fast inte-
grators, active filters, and applications requiring speed,
accuracy and low cost.
The LT1190 is available in 8-pin PDIP and SO packages
with standard pinouts. The normally unused Pin 5 is used
for a shutdown feature that shuts off the output and
reduces power dissipation to a mere 15mW.

Ask a question about compilation, simple
My book says "MOV BX 5" the result will be BX=0005; that is ,BH=00 and BL=05; The BX register is 16 bits, so isn't the high bit (BH) 0000 and the low bit (BL) 0005? Is it okay to write it like that?...
