OPA2188AQDGKRQ1 is a type of linear-amplifier instrumentation op-amp. It can be used to buffer a signal with high gain and robust common-mode rejection (CMRR). In its normal operation, the integrated circuit acts as a differential amplifier with a nominal gain of 100 (an output voltage of 100 times larger than the voltage input). It is engineered to perform in a wide range of frequencies, from sixty kilohertz up to one hundred megahertz, and possesses an overall bandwidth of about 30V/usec.
OPAs are mainly employed in applications where a low-supply voltage needs to be amplified such as medical instrumentation, analog-to-digital (ADC) interfaces and communication receivers. The OPA2188AQDGKRQ1 model is suitable for amplification of medium-low frequency signals due to its wide bandwidth and low noise relative to low-noise resistors. It has been designed with superior common-mode rejection characteristics and can also be used to isolate signals in datasheets.
Apart from the amplifying properties of the OPA2188AQDGKRQ1, it presents a fast slew rate and high unity-gain bandwidth enabling optimal analog operation. The rise and fall times of the signal generated by the amplifier are quite short and usually of the order of 10µS. This is particularly well-suited for the low noise amplification of square waves and for time-critical operations in the process control area.
The working principle of the OPA2188AQDGKRQ1 is based on the classic equation for a single-ended op-amp, namely A=Vout/Vin. In single ended operation, the amplifier only amplifies the input voltage in terms of the value present at the output terminal of the op-amp. In order to measure the gain more accurately, the two input and output ports of the op-amp should be connected together. This will result in the gain being determined by the ratio of resistance between the two ports.
The gain of an amplifier depends upon the capacitances connected to the power pins. If there is an increase in the circuit capacitances, the gain of the amplifier will decrease considerably. The OPA2188AQDGKRQ1 is specially designed to have very low input capacitance and hence operates effectively, even in the case of high frequency operation. Moreover, the voltage noise generated by the op-amp is also low, making it suitable for op-amp applications.
In summary, the OPA2188AQDGKRQ1 is an integrated circuit that amplifies a signal with high gain, robust common-mode rejection characteristics, and high slew rate, making it suitable for applications such as medical instrumentation, ADC interfaces, and communication receivers. Moreover, the voltage noise generated by this linear amplifier is low, giving it a wide range of operating frequencies and bandwidth.
