The OPA2180QDGKRQ1 device is an precision, high-speed, ultra-low-noise operational amplifier designed to meet the stringent requirements of modern microphone preamplifiers and other professional audio applications.

The OPA2180QDGKRQ1 integrates several new features that make it an ideal choice for preamplifier designs, from ultra-low noise (-100 dBV noise) to low distortion at unity gain (0.0006 % THD+N, A-weighted). It also integrates an internal temperature compensation circuit and an output voltage swing of 20 dB above the supply rails.

The OPA2180QDGKRQ1 has a wide range of common application fields such as mixing consoles, audio analyzers, oscilloscopes, and transmission systems. Additionally, its low noise and low distortion features also make it suitable for instrumentation amplifiers, level transducers, and remote control applications.

The working principle of the OPA2180QDGKRQ1 is based on the conventional operational amplifier or ‘op-amp.’ An op-amp consists of a differential input stage followed by an amplifier, where the differential input stage consists of two input terminals (a non-inverting input and an inverting input) and two output terminals (the output and the feedback).

The input signal of the OPA2180QDGKRQ1 is applied to the input terminals and amplified by the differential stage. The output of the differential stage is then fed back to the inverting input terminal, which is employed to achieve a closed-loop gain. This arrangement enables the OPA2180QDGKRQ1 to achieve excellent noise and distortion performance.

In addition to its precision and high-speed operation, the OPA2180QDGKRQ1 has a high slew rate of up to 18V/µs, which makes it an ideal choice for high-fidelity audio systems. Furthermore, the OPA2180QDGKRQ1 features a wide supply voltage range, making it suitable for a variety of battery-powered applications.

The OPA2180QDGKRQ1 is an ideal choice for microphone preamplifiers, instrumentation amplifiers, level transducers, and remote control applications due to its low noise, low distortion, high-speed, and wide supply voltage range. Its conventional op-amp design is suitable for most applications and its internal temperature compensation circuit ensures reliable operation.
