The OPA2335AIDGKR amplifier is a product of Burr Brown, now part of Texas Instruments, and is a member of their OPA2335 series. These amplifiers are designed to be operated from a single, dual or split supply ranging from 1.5V to 15V.

These ampliders are designed for a wide range of applications, including instrumentation, linear amplifiers and buffer amps. In instrumentation applications, the OPA2335AIDGKR is highly suitable for amplifying signals that require low noise and high common mode rejection, as well as low distortion and high slew rate for precision measurements. In linear amplifiers and buffer amplifiers, this amplifier can be used to increase gain, provide voltage gain and also provide control of output swing.

The OPA2335AIDGKR offers several features that make it suitable for use in these applications. It has a typical slew rate of 1.2V/µs, with a minimum value of 0.5V/µs, and a maximum output current of 20mA. The input common-mode voltage range is ±12V, and the amplifier has an open loop gain of 86dB. In addition, the amplifier has a low offset voltage of just 4.5mV, and can operate at the very low noise levels of less than 7µV. The amplifier also has a good power supply rejection ratio greater than 70dB.

The OPA2335AIDGKR also has a low quiescent current of 10mA, which makes it power efficient and suitable for battery-powered applications. In addition to its low power consumption, the amplifier also features a low input bias current of 1nA, and a low output impedance of 15Ω, allowing it to drive low impedance output loads efficiently.

In order to understand how the OPA2335AIDGKR works, it is important to understand the principles behind linear amplifiers. A linear amplifier is an electronic circuit that amplifies the input signal without distorting its waveform. The purpose of a linear amplifier is to increase the amplitude of a signal without introducing distortion or impairing the signal-to-noise ratio of the signal.

The OPA2335AIDGKR works by using the operational amplifier (op amp) principle. In this principle, the amplifier uses two amplifying transistors to increase the amplitude of the input signal. The input signals are applied across the amplifier’s input terminals, and the output voltage is determined by the voltage between the output terminals. The op amp also features negative feedback, which ensures that the output voltage is a accurate as possible, and minimizes the distortion. This device is capable of amplifying signals up to a voltage gain of 150, bearing in mind the slew rate and output current specs.

In summary, the OPA2335AIDGKR is a linear amplifier device suitable for applications such as instrumentation, linear amplifiers and buffer amps. It features a high slew rate, low offset voltage, low noise, high common mode rejection, low input bias current, low power consumption and low output impedance. The amplifier is designed to work using the operational amplifier principle, which involves the use of two amplifying transistors to increase the amplitude of the input signal, and negative feedback to minimize any distortion.
