LTC6081 Single Supply Strain Gauge Amplifier

Aug 6th 2007
A dual CMOS amplifier with low supply voltage operation and rail to rail input and output performance makes single supply operation easy. This circuit provides a gain of 1001 to the small differential input signal from a low voltage strain gauge bridge transducer. High input impedance allows for high valued input resistors to ...

Low Side Current Sense

Aug 6th 2007
Sensing the amount of current through a load on the low side has the disadvantage of raising the return connection to the load from ground. The advantage of such an approach is that it is very easy to implement using a basic non-inverting gain stage. The LTC6081 operates linearly down to ground also in this single supply example. ...

LTC6081 Two Op Amp Instrumentation Amplifier

Aug 6th 2007
Instrumentation amplifiers present a high input impedance to a differential input signal source and provide a single ended output. This circuit uses the non-inverting inputs of each amplifier of the dual LTC6081 for the differential input terminals. The gain is set with external resistors to over 1000. A CMRR trim cancels the ...

LTC6081 Shock Sensor Amplifier (Accelerometer)

Aug 6th 2007
A shock sensor is a capacitive piezoelectric element which generates a charge under physical acceleration. This charge can be converted to a voltage and filtered using high valued resistors and a high input impedance CMOS amplifier such as the LTC6081. This circuit has a gain of 100 and output 109mV per g of acceleration. ...

LTC6081/LT1025 Type K Thermocouple Signal Conditioner with ±350V Protection from Accidental Contact and Cold Junction Compensation

Dec 9th 2003
A high input impedance amplifier permits the use of large valued input resistors and retains signal accuracy. This is very useful for protecting both the amplifier and cold junction compensator in thermocouple applications as the sense element can often be inadvertently connected to destructive voltage potentials. The 1MΩ ...
