The OP281GSZ is a high performance amplifier designed for a wide range of applications that require precise and accurate amplification, such as instrumentation, buffer and linear amplifiers. This amplifier is capable of delivering precise outputs with the wide supply voltage range, low noise and fast settling times, making it the ideal solution for instrumentation, medical and industrial applications.

Features:

The OP-281GSZ features an ultra-low noise, low distortion, and wide bandwidth design that is designed to operate within a 12-24 VDC (15V typical) supply range. It also has an input gain of up to 24 dB and an adjustable gain of up to 20 dB. The device also features a wide bandwidth of up to 600 kHz, slew rates of up to 11.5 V/µs, fast settling time of 150 µs, and an input impedance of 100 kΩ.

Applications:

The OP281GSZ is suitable for a variety of applications such as level control and signal conditioning in instrumentation, medical and industrial applications. It can be used as a preamp in data acquisition systems, as an amplifier for signal conditioning and loop control in process control systems, for audio level control and signal attenuation in studio and studio recordings, and for gain control and signal conditioning in video applications. The device is also suitable for applications such as audio signal generation, signal amplification and gain control, switching, and filtering. It can also be used in low-noise, high-precision signal conditioning and power amplifiers, as well as high-power audio amplification.

Working Principle:

The OP281GSZ uses a classical negative feedback topology to adjust the gain and reduce noise and distortion. The device consists of an input stage with a differential input, a low-noise preamplifier stage, and an output stage with a output buffer.The negative feedback around the amplifier provides controlled gain and improved signal to noise ratio. The input stage is designed with common mode rejection, and the output stage incorporates a unity gain buffer to achieve low output impedance and low distortion. The device also includes an adjustable external gain control. This allows the user to adjust the output level of the amplifier for optimum performance in different applications.
