ADA4254ACPZ

ADA4254 is a zero drift, high voltage, low power programmable gain instrumentation amplifier (PGIA) designed for process control and industrial applications. The ADA4254 features 12 binary weighted gains ranging from 1/16V/V to 128V/V and three scaling gain options of 1V/V, 1.25V/V and 1.375V/V, resulting in 36 possible gain settings. The power consumption of the ADA4254 is a mere 22mW, making the device an excellent choice for industrial systems that demand precision, robustness and low power. Typical application includes universal process control front ends, data acquisition systems and test and measurement systems.
