The LTC
1250 is a high performance, very low noise zero-
drift operational amplifier. The LTC1250’s combination of
low front-end noise and DC precision makes it ideal for use
with low impedance bridge transducers. The LTC1250
features typical input noise of 0.75
μ
V
P-P
from 0.1Hz to
10Hz, and 0.2
μ
V
P-P
from 0.1Hz to 1Hz. The LTC1250 has
DC to 1Hz noise of 0.35
μ
V
P-P
, surpassing that of low noise
bipolar parts including the OP-07, OP-77, and LT1012.
The LTC1250 uses the industry-standard single op amp
pinout, and requires no external components or nulling
signals, allowing it to be a plug-in replacement for bipolar
op amps.
The LTC1250 incorporates an improved output stage
capable of driving 4.3V into a 1k load with a single 5V
supply; it will swing
±
4.9V into 5k with
±
5V supplies. The
input common mode range includes ground with single
power supply voltages above 12V. Supply current is 3mA
with a
±
5V supply, and overload recovery times from
positive and negative saturation are 0.5ms and 1.5ms,
respectively. The internal nulling clock is set at 5kHz for
optimum low frequency noise and offset drift; no external
connections are necessary.
The LTC1250 is available in standard 8-pin ceramic and
plastic DIPs, as well as an 8-pin SOIC package.
