The LM393ADR is an integrated circuit (IC) with dual differential analog comparators manufactured by Texas Instruments Inc. It is an upgrade to the traditional LM393, and a complementary alternate to the LM393A.The LM393ADR is an 8-pin package, and has two independent voltage comparators which are designed to detect a small voltage between two inputs. It has a wide range of operating voltages up to 32V, and includes standby features such as a disable function and a CMOS-compatible output.The LM393ADR includes a number of features which make it a great choice for many electronic applications. It is a low power consumption design, and is rated to operate at temperatures between -40 to +125°C. The circuit is also highly flexible and includes hysteresis input, hysteresis output, TTL-compatible output, latch enable-disable pins, and an input common mode voltage range.The LM393ADR does not require any external components, and is A grade rated for low noise. It provides an economical solution for many applications, and is ideal for use in industrial products or any applications that require efficient monitoring of electrical signals.
