INA350 – Tiny and low-power (100 µA) selectable gain instrumentation amplifier
https://www.electronics-lab.com/ina350-tiny-and-low-power-100-%c2%b5a-selectable-gain-instrumentation-amplifier/
INA350 is a selectable-gain instrumentation amplifier that offers four gain options across INA350ABS and INA350CDS variants available in small packages. INA350ABS has gain options of 10 or 20 and INA350CDS has gain options of 30 or 50. These gain options can be selected by toggling the gain select (GS) pin. INA350 is ideal for bridge-type […]

https://www.electronics-lab.com/strain-gauge-sensor-amplifier-or-single-supply-instrumentation-amplifier/
This is a new project, a single supply instrumentation amplifier with onboard bridge configuration, and a 2.5V precision reference voltage chip. The project can be configured for applications such as thermocouple amplifier, bridge amplifier, ECG amplifier, pressure sensors, medical instrumentation, portable instrumentation, RTD sensor amplifier. The project is based on INA333 micropower, zero drift, rail […]
The Differential OPAMP Amplifier
https://www.electronics-lab.com/article/the-differential-opamp-amplifier/
Introduction In the previous tutorials, we talked about the inverting op-amp and non-inverting op-amp, we considered configurations that take a single input on either pin “-” or “+” of the operational amplifier, while the other pin is grounded. However, it is possible, as we will see during this article, to supply both inputs of an […]
Simple circuit provides precision ADC interface
https://www.electronics-lab.com/simple-circuit-provides-precision-adc-interface/
Moshe Gerstanhaber @ edn.com provides an simple ADC interface using instrumentation amplifier IC. Real-world measurement requires the extraction of weak signals from noisy sources. High common-mode voltages are often present even in differential measurements. The usual approach to this problem is to use an op amp or an instrumentation amplifier and then perform some type of […]
