The MAX991ESA+ is an advanced low-power, single-supply, rail-to-rail operational amplifier specifically designed to optimize performance in single-supply data acquisition systems. It operates from a single supply as low as ±2.7V, or from dual supplies up to ±15.0V. Low quiescent current (12μA typ) and low output-voltage swing (0.4V) allow for efficient low power operation. It has a field of applications in data acquisition systems, sample-and-hold amplifiers, and analog signal-processing blocks.
The MAX991ESA+ belongs to the linear-comparator category, which basically means that it has the capability to distinguish between two analog voltages and then control the output accordingly. It allows input signal amplitudes to reach within a couple hundred millivolts (mV) of the supply rails. The MAX991ESA+ is capable of operating and making comparisons between different types of input signals, such as single-ended, differential and wide bandwidth signals. It enhances amplifier performance when compared to single supply and dual supply designs.
The MAX991ESA+ has a typical input common-mode voltage range of -0.3V to +6V, and a guaranteed common-mode voltage range of -1.5V to +5.5 volts. This allows it to operate in a very broad range of signal strengths from very small to very large. In addition to this, the MAX991ESA+ has an improved common-mode rejection ratio (CMRR) of 94dB and an input offset voltage of ±2mV. The device also offers a high common-mode voltage rejection (CMR >100dB).
The MAX991ESA+ working principle is as follows. It monitors the input signal for a pre-determined voltage. The output is set to high if the input signal is higher than the pre-determined voltage, and to low if the input signal is lower. This makes it useful for such applications as signal conditioning and signal comparators. In addition, it can act as an analog level detector. When used as a level detector, the output of the device will change accordingly when the input voltage reaches the desired level.
The MAX991ESA+ applies its excellent performance in various fields, such as opto-isolator interface, data acquisition systems, sample-and-hold amplifiers, pulse width modulation (PWM) and more. It is a versatile and reliable operational amplifier, boasting excellent features such as its wide input common-mode voltage range and low power consumption. With its unique design and working principle, the MAX991ESA+ is well suited for a variety of applications, from signal conditioning to level detection.
