ADA4254ARUZ-R7

ADA4254 is a zero drift, high voltage, low power programmable gain instrumentation amplifier (PGIA) designed for process control and industrial applications. The power consumption of the device is a mere 22mW, making the device an excellent choice for industrial systems that demand precision, robustness, and low power. This high level of precision maximizes dynamic range and greatly reduces calibration requirements in many applications. The input multiplexer provides ±60V protection to the high impedance inputs of the amplifier, while providing the capability to switch between two input sources. In addition, electromagnetic interference (EMI) filters block harsh RF noise from the sensitive inputs of the amplifier. It is used in applications such as universal process control front ends, data acquisition systems, test and measurement systems etc.
