Modern battery-cell voltages of 3 to 3.6 V require circuits that offer efficient low-voltage operation. This Design Idea proposes an ac-coupled instrumentation-amplifier design that features high CMRR (common-mode-rejection ratio), wide dc ...
When processing signals from analog sensors, you frequently encounter wide variations in attenuation among communication channels or sensors. Or, you face situations in which several identical sensors within a supervised system return signals of ...
Resistance-based transducers, such as strain gauges and piezoresistive devices, find common use in the measurement of several physical parameters. For applications in which digital processors or microcontrollers serve for data acquisition and ...
Many single-supply applications need precision amplifiers that can operate from 5 V or lower. Although many precision, single-supply op amps are currently available for configuring as 2- and 3-amplifier instrumentation amplifiers (IAs), these ...
