LTC1250  
Very Low Noise  
Zero-Drift Bridge Amplifier  
U
DESCRIPTIO  
FEATURES  
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 0.75µVP-P from 0.1Hz to  
10Hz, and 0.2µVP-P from 0.1Hz to 1Hz. The LTC1250 has  
DCto1Hznoiseof0.35µVP-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.  
■
Very Low Noise: 0.75µVP-P Typ, 0.1Hz to 10Hz  
■
DC to 1Hz Noise Lower Than OP-07  
■
Full Output Swing into 1k Load  
■
Offset Voltage: 10µV Max  
■
Offset Voltage Drift: 50nV/°C Max  
■
Common Mode Rejection Ratio: 110dB Min  
■
Power Supply Rejection Ratio: 115dB Min  
■
No External Components Required  
■
Pin Compatible with Standard 8-Pin Op Amps  
■
Available in Standard 8-Pin Plastic DIP  
and 8-Pin SO Packages  
U
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.
