8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.

8.1 Application Information

The LM339-MIL device is specified for operation from 2 V to 36 V (±1 V to ±18 V) over the temperature range of 0°C to 70°C. While it may seem like a comparator has a well-defined and somewhat limited functionality as a 1-bit ADC, a comparator is a versatile component which can be used for many functions.

8.2 Typical Application

8.2.1.1 Design Requirements

The basic usage of a comparator is to indicate when a specific analog signal has exceeded some predefined threshold. In this application, the negative input is tied to a reference voltage, and the positive input is connected to the input signal. The output is pulled up with a resistor to the logic supply voltage, V+.

For an example application, the supply voltage is 5 V. The input signal varies between 1 V and 3 V. Specifically as an example, to know when the input exceeds 2.5 V, set the VREF voltage to 2.5 V.
