TS372CN Integrated Circuits (ICs)

Linear - Comparators

The TS372CN is an integrated circuit designed to compare two values and output accordingly. It is a linear comparator with a maximum input voltage of 36V. It is available in a 8-lead DIP package, making it well suited for high-density applications. It is also available in a surface mount package.

The TS372CN has two inputs, INA and INB, and an output pin OUT. The output signal is either high or low depending on the relationship between INA and INB values. It is a high speed comparator with a maximum propagation delay of 3.5ns. It also has a low power consumption of 5mA.

The TS372CN compares two input signals, INA and INB, and outputs high voltage on the output pin when INA is greater than INB and low voltage output when INB is greater than INA. The two inputs, INA and INB, can be either complementary (different in polarity) or non-complementary (same in polarity). For symmetric operation the two inputs should be the same in scale and offset. It also features two wide input common-mode ranges, 0V - 36V, and –2V - 38V.

The TS372CN is suitable for use as a high-speed single channel comparator in a wide range of applications such as sample-and-hold controllers, operational amplifiers, analog-to-digital (A/D) converters and pulse-width-modulation (PWM) controllers. It is also suitable for use in other applications such as sensor interface circuits, level-shifting circuits, amplitude modulation circuits and peak detectors.

The TS372CN is manufactured in an advanced CMOS process, and is provided with over-temperature protection and latch-up protection. This makes it highly reliable in a wide variety of environments and applications.

Working Principle

The TS372CN compares two input signals, INA and INB, and outputs a higher voltage on the output pin when INA is greater than INB, and a lower voltage when INB is greater than INA. This device is an open-drain comparator so it does not require any external pull-up resistor. The inputs, INA and INB, must be within the common mode voltage range of -2V to 38V, and the output will remain within the limits of the output range.

The TS372CN is designed to operate in the most efficient way possible to provide the fastest comparison results. It is designed with discrete-time methods such as connected-mode and set-reset latches to insure maximum noise immunity of the output signal. The comparator allows for hysteresis, which means that the switching voltage can be adjusted to compensate for noise and sudden changes in the input voltage.

The device features protection features such as over-temperature protection, latch-up protection, and ESD protection to ensure reliability and long-term performance. The chip also offers low power, and low current consumption which are highly desired attributes in an integrated circuit. The low current consumption and low power consumption also helps to increase the battery life of the device.
