DESCRIPTION
The LT
廬
1354 is a low power, high speed, high slew rate
operational amplifier with outstanding AC and DC perfor-
mance. The LT1354 has much lower supply current, lower
input offset voltage, lower input bias current, and higher
DC gain than devices with comparable bandwidth. The
circuit topology is a voltage feedback amplifier with the
slewing characteristics of a current feedback amplifier.
The amplifier is a single gain stage with outstanding
settling characteristics which makes the circuit an ideal
choice for data acquisition systems. The output drives a
500鈩?load to
鹵12V
with
鹵15V
supplies and a 150鈩?load
to
鹵2.5V
on
鹵5V
supplies. The amplifier is also stable with
any capacitive load which makes it useful in buffer or cable
driver applications.
The LT1354 is a member of a family of fast, high perfor-
mance amplifiers using this unique topology and employ-
ing Linear Technology Corporation鈥檚 advanced bipolar
complementary processing. For dual and quad amplifier
versions of the LT1354 see the LT1355/LT1356 data
sheet. For higher bandwidth devices with higher supply
current see the LT1357 through LT1365 data sheets.
Singles, duals, and quads of each amplifier are available.
