LTC1250

Very Low Noise

Zero-Drift Bridge Amplifier

DESCRIPTIO

EATURE

The LTC^®1250 is a high performance, very low noise zero-

drift operational amplifier. The LTC1250’s combination of

lowfront-endnoiseandDCprecisionmakesitidealforuse

with low impedance bridge transducers. The LTC1250

features typical input noise of 0.75µV_P-Pfrom 0.1Hz to

10Hz, and 0.2µV_P-Pfrom 0.1Hz to 1Hz. The LTC1250 has

DCto1Hznoiseof0.35µV_P-P, surpassingthatoflownoise

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.

Strain Gauge Amplifiers

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.
