“Classic” High-Precision Low Side Current Sense

Nov 23rd 1999
This configuration is basically a standard non-inverting amplifier. The op amp used must support common-mode operation at the lower rail and the use of a Zero-Drift type (as shown) provides excellent precision. The output of this circuit is referenced to the lower Kelvin contact, which could be ground in a single-supply application. ...

Single Supply Type K Thermocouple Signal Conditioning Amplifier with Cold Junction Compensation

Nov 23rd 1999
The LTC2050 is a zero-drift precision chopper stabilized operational amplifier available in the 5- or 6-lead SOT-23 and SO-8 packages. It minimizes board area while providing uncompromising DC performance, including 3mV (max) DC offset and 30nV/°C (max) DC offset drift. It operates from a 2.7V supply while still supporting ...

Low Noise, Low Power Photodiode Amplifier With DC Precision

Nov 23rd 1999
Instead of simply grounding the LT6202 noninverting input, an LTC2050 drives it (and therefore the source) exactly to where it needs to be for zero JFET gate voltage. Output offset is 200µV and output noise is 2mVP-P measured in a 20MHz bandwidth. ...

High Resolution Battery-Powered Robust Type K Thermocouple Signal Conditioning Amplifier with Cold Junction Compensation

Nov 23rd 1999
The circuit is used as a plug-in adapter for common digital multimeters and is completely portable. This circuit employs the LT1025 thermocouple compensator to improve accuracy over a wide range of ambient conditions and is mounted close to the thermocouple connection points for optimal thermal tracking. It precludes the need ...

Differential Bridge Amplifier

Nov 23rd 1999
The LTC2050HV are zero-drift operational amplifi ers available in the 5- or 6-lead SOT-23 and SO-8 packages. The LTC2050 operates from a single 2.7V to 6V supply. The LTC2050HV operates on supplies from 2.7V to ±5.5V. The current consumption is 800μA and the versions in the 6-lead SOT-23 and SO-8 packages offer power shutdown ...
