DescripTion
215MHz, Rail-to-Rail Output,
1.1nV/
√Hz, 3.5mA Op Amp Family
The LT6230/LT6231/LT6232 are single/dual/quad low
noise, rail-to-rail output unity-gain stable op amps that
feature 1.1nV/√Hz noise voltage and draw only 3.5mA of
supply current per amplifier. These amplifiers combine
very low noise and supply current with a 215MHz gain-
bandwidth product, a 70V/s slew rate and are optimized
for low supply voltage signal conditioning systems. The
LT6230-10 is a single amplifier optimized for higher gain
applications resulting in higher gain bandwidth and slew
rate. The LT6230 and LT6230-10 include an enable pin
that can be used to reduce the supply current to less
than 10A.
Theamplifierfamilyhasanoutputthatswingswithin50mV
of either supply rail to maximize the signal dynamic range
in low supply applications and is specified on 3.3V, 5V and
±5Vsupplies.Theen√ISUPPLYproductof1.9peramplifier
is among the most noise efficient of any op amp.
The LT6230/LT6230-10 are available in the 6-lead SOT-23
package and the LT6231 dual is available in the 8-pin SO
package with standard pinouts. For compact layouts,
the dual is also available in a tiny dual fine pitch leadless
package (DFN). The LT6232 is available in the 16-pin
SSOP package.
