The OP495GS-REEL is a part of the Linear–Instrumentation Operational Amplifiers and Buffers Amplifiers Category. It is an ultra-low noise, rail-to-rail output precision CMOS Operational Amplifiers. This device provides very low noise, low distortion and high common-mode rejection ratio. It is ideal for transducer and interfacing applications, direct-drive of high-performance ADC and DACs and applications that require low supply current and noise.

The OP495GS-REEL has both differential and single-ended inputs in order to drive high-performance analog-to-digital converters. It has rail-to-rail output swing that eliminates the need of buffers or gain devices. It provides a very large bandwidth of up to 545MHz and a very low distortion of only −85dBc. With a low supply current of only 10μA/channel, it is an efficient solution for bridging low-level transducers.

When it comes to the application field of the OP495GS-REEL, it is commonly used in professional audio and medical applications. In medical instrumentation, the OP495GS-REEL is usually used to implement low-noise AC measurements, line-receiver amplifiers, differential linearities and low-level transducer signals. In professional audio applications, the OP495GS-REEL is used to realize low-noise outputs for high-resolution A/D and D/A converters, high-precision single-ended to differential level converters and low-noise filter topologies.

As for the working principle of the OP495GS-REEL, the device consists of two independent internally-compensated amplifiers operating from the same positive and negative power supplies. Its inputs are high-impedance differential and single-ended, while its outputs are rail-to-rail tolerant with no external tail current. The OP495GS-REEL is designed to operate from a single supply, dual supply or bipolar supply. It operates with a maximum supply voltage of 36V and a minimum operating temperature of −40°C with a maximum quiescent current of 300μA/channel.

The OP495GS-REEL is a very efficient device, which is capacitively coupled in order to minimize noise and distortion. Its power supply rejection ratio of 89dB and its output voltage swing of 7V enables it to drive low-level transducers with precision and reliability. It also features an internal bandgap reference and a shutdown input, which helps reduce power dissipation quadratically by shutting off channels that are not in use.

In summary, the OP495GS-REEL is an ultra-low noise, rail-to-rail output precision CMOS Operational Amplifier that is used in professional audio and medical applications. It is designed with high-impedance differential and single-ended inputs and rail-to-rail output swings. It has a fast bandwidth of up to 545MHz and it facilitates a maximum supply voltage of 36V. Furthermore, it has a capability of driving low-level transducers and it also has a power supply rejection ratio of 89dB and output voltage swings of 7V. In addition, the OP495GS-REEL also features an internal bandgap reference and shutdown inputs.
