Linear-comparator devices are used to compare two analogue signals and output a logic signal in response to an inequality between the two signals.

The LM193AH is a low-power voltage comparator designed for use in automotive applications. It has an adjustable hysteresis, fast response time, and offers rail-to-rail input and output capability. The comparator is also operable from both single and dual-supply voltage sources. This makes it ideal for use in applications that require a comparator to control a wide range of systems where low power consumption is critical.

The LM193AH is a 3 V to 36 V single supply voltage operated, fast response, dual-input comparator. It offers wide input dynamic range and very high output current capability. The two input pins are referred to as the "non-inverting" (plus) and "inverting" (minus) inputs. When the voltage at the non-inverting input is higher than the voltage at the inverting input, an output of "1" (VCC) is generated. If the voltage at the non-inverting input is lower than that at the inverting input, an output of "0" (GND) is generated. This simple feature of the LM193AH makes it applicable in many different types of circuits.

The LM193AH comparator has two control pins: a hysteresis pin and a reset pin. The hysteresis pin is used to adjust the level at which the comparator changes its state; this level is called the "trigger point". The reset pin is used to put the comparator in the low-power consumption reserve mode. In this mode, the comparator will only draw a small current, which extends its battery life while the comparator is not being used.

The LM193AH comparator also features a power-on reset, which prevents it from oscillating during power-up. This feature makes the LM193AH an ideal choice for noisy environments where spurious signals can cause comparators to malfunction.

The LM193AH is popularly used in automotive systems, such as low and high voltage cutoff circuits, engine control systems, transmission systems, and in audio systems for detecting speaker faults and audio level control. It is also used in circuits for battery management, consumer electronics and communication systems.

The LM193AH comparator is a reliable, low-power device and is a popular choice for many applications. Its wide input dynamic range, fast response time, adjustable hysteresis and rail-to-rail output capability make it an ideal choice for a variety of designs. With its low power consumption, it is an excellent choice for applications where power conservation is important.
