DESCRIPTION
The LT
rate operational amplifi er with excellent DC performance.
The LT1812 features reduced supply current, lower input
offset voltage, lower input bias current and higher DC gain
than other devices with comparable bandwidth. A power
saving shutdown feature reduces supply current to 50μA.
The circuit topology is a voltage feedback amplifi er with the
slewing characteristics of a current feedback amplifi er.
The output drives a 100Ω load to ± 3.5V with ±5V supplies.
On a single 5V supply, the output swings from 1.1V to
3.9V with a 100Ω load connected to 2.5V. The amplifi er
is stable with a 1000pF capacitive load which makes it
useful in buffer and cable driver applications.
The LT1812 is manufactured on Linear Technology’s
advanced low voltage complementary bipolar process.
The dual version is the LT1813. For higher supply voltage
single, dual and quad operational amplifi ers with up to
70MHz gain bandwidth, see the LT1351 through LT1365
data sheets.
