A MAX495CPA is an operational amplifier (“op-amp”) featuring fast settling times, wide bandwidth, low distortion, and low offset current. The MAX495CPA is suitable for a variety of applications including audio, low voltage data acquisition, and sensor level shifting.

The MAX495CPA is a rail-to-rail output type amplifier. A typical application would be a gain stage driving a transducer in a sensor interface or a similar application. The MAX495CPA amplifiers feature low voltage operation, Internally selectable gains of either 1 or 10, and high output current drive = 25mA.

One of the most attractive features of the MAX495CPA is their exceptionally low distortion. For applications requiring low distortion, an external compensation capacitance is required to reduce distortion at high frequencies. This can be accomplished with a single-pole type of circuit with the capacitor connected from the output to the inverting input. The MAX495CPA amplifiers can also be operated with open-loop gains of 10,000 or 100,000.

The MAX495CPA amplifiers are designed to minimize errors caused by the nonlinear nature of op-amps. They achieve this by using a multi-stage topology featuring the Miller effect Auto-Zero sigmoidal cells which minimize non-linearities by reducing offset voltage, nullifying op-amp gain, and increasing slew rates. This makes the MAX495CPA suitable for AC/DC input-coupled amplifiers, as well as for temperature-independent linear conditioners.

The MAX495CPA amplifiers have several protection features to guard against over-current and over-temperature conditions. First, an over voltage protection feature that automatically shuts down the amplifier if the output voltage exceeds 20V. Second, an over temperature protection circuitry that shutdowns the device before the internal junction temperature exceeds +140°C.

The MAX495CPA amplifiers are ideal for low voltage applications, including low voltage power sensors and other data acquisition systems, acoustic transducers and speaker systems, instrumentation amplifiers, and automotive applications. The MAX495CPA offers high performance with low power consumption, low noise, and reliable operation in a wide temperature range, making it suitable for a variety of applications.

The MAX495CPA is a low noise, low power, high bandwidth, monolithic amplifier that is ideal for data acquisition and sensor level shifting applications. This device features rail-to-rail output, fast settling times, wide bandwidth and low distortion, making it suitable for AC as well as DC input-coupled amplifiers. The built-in protection features ensure reliable operation for a wide range of applications.
