The MAX988ESA+ is a selective comparator operating with an industry-leading low quiescent current (420nA). It is made in the Linear — Comparators category, with internal hysteresis and noninverting single-ended input and output. The low operating current and low offset voltage (<2mV) make the MAX988ESA+ suitable for applications with a limited power budget or where a low offset voltage is essential.

The low offset voltage of the MAX988ESA+ is possible due to the unique architecture of the comparator. The threshold voltage of the comparator is generated by a proportional-to-absolute-temperature (PTAT) reference circuit, which self-biases the input transistor and sets the Vos and bias current. The device also features a single-ended-input architecture which further minimizes the offset voltage.

The MAX988ESA+ is designed to utilize its ultra-low quiescent current. The device is designed with a high input impedance and a low output impedance. This allows the device to be used in applications such as amplifiers, where low input bias current and high gain are desired features.

It can be used for applications such as motor control, voltage limiters, and temperature monitoring. The device does not operate as a standard comparator, as it utilizes hysteresis at the threshold level, allowing the output to remain stable until the input level crosses the thresholds. This hysteresis helps to reduce noise and provide greater stability in the output signal.

The MAX988ESA+ can also be used as an operational amplifier. This amplifier can be used in a variety of applications such as signal conditioning, amplifying small signals, inverting amplifier, and even as a gain boost circuit. The device is designed to provide a stable performance over a wide range of temperatures and voltages.

The MAX988ESA+ can also be used in active filters, oscillators, and signal detectors. These applications rely on the low offset voltage and wide signal range of the MAX988ESA+. Additionally, the comparator is compatible with a variety of power sources, including rail-to-rail inputs and supplies covering up to 100V. This makes the MAX988ESA+ an ideal comparator solution for applications requiring wide dynamic ranges and low power consumption.

In summary, the MAX988ESA+ is a versatile, low quiescent current comparator operating with industry-leading low offset voltage and hysteresis. This device is suitable for applications requiring wide dynamic range, low input bias current and high gain. Its low power consumption makes it an ideal solution for a number of applications, including amplifiers, motor control, voltage limiters, temperature monitoring, and active filters.
