OPA228UG4 is a dual-channel, low noise and high precision operational amplifier (op-amp) designed for instrumentation and data acquisition applications. It is a high-performance, low-power device which allows quick and accurate measurement and analysis of input signals, specifically those with varying frequencies. The device’s design provides a wide range of gain, ripple rejection and input common-mode range, enabling a variety of applications in medical and industrial equipment, test and measurement, automotive, and consumer electronics.

The OPA228UG4 is part of the Burr-Brown portfolio of op-amps. It features two independent operational amplifiers with high speed, low noise and low offset voltage. It has a wide voltage gain range from 10 mV/V to 2 V/V, a wide input common-mode range from 2 V to 16 V and a maximum slew rate of 9 V/µs. It also has an excellent input voltage noise density of 2 nV/√Hz and a typical settling time of 5 µs. The device is available in an 8-pin minidip and SOIC package for easy system integration.

The OPA228UG4 is ideal for a variety of instrumentation and data acquisition applications such as temperature, pressure and torque sensors and bridge amplifiers, as well as battery-powered systems and medical electronics. The device’s low noise and low offset voltage make it perfect for signal conditioning and signal processing applications, as it can accurately and reliably convert analog signals into digital signals. The excellent input voltage noise density also helps reduce signal-to-noise ratio (SNR) errors.

The working principle of the OPA228UG4 is based on differential amplifier technology. This technology allows the device to take two input signals and amplify the difference between them. The differential amplifier contains two transistors and amplifies the output signal with respect to the input signal. This difference amplifier has two inputs and one output, and is usually connected to an op-amp or comparator to provide additional gain and protection from overloads and transients. The OPA228UG4 also features two internal precision current sources for offset cancellation and temperature drift compensation.

The OPA228UG4 is designed for use in a wide range of applications, from data acquisition and signal conditioning to medical electronics and automotive systems. It offers excellent performance, low noise, low offset voltage and wide input common-mode range, making it suitable for a variety of situations. With its high performance and low power, the OPA228UG4 is an ideal choice for instrumentation and data acquisition applications.
