LMV393IDGKR – TEXAS INSTRUMENTS

The Texas Instruments LMV393IDGKR is a dual comparator integrated circuit housed in a space-saving 8-pin SOIC (small outline integrated circuit) package. It operates from a single supply voltage ranging from 1.8V to 5.5V, offering a wide input common-mode voltage range that extends almost to the rails. Each comparator features rail-to-rail input and output capabilities, enabling maximum signal swing utilization. The device boasts a low input bias current of typically 25nA, minimizing errors in high-impedance applications. Propagation delays are typically under 120ns, making it suitable for moderately fast switching applications._x000D_

The LMV393IDGKR’s low power consumption (typically 0.7mA per comparator at 3V) is a key advantage in battery-powered systems. Its open-collector outputs allow for easy connection to various loads, including LEDs, relays (with appropriate level shifting), and other logic circuits. Common applications include window comparators, zero-crossing detectors, and simple analog-to-digital converters. Its ability to operate reliably across a wide voltage range and its low input bias current make it particularly well-suited for precision sensing and low-power instrumentation applications where accurate signal detection is crucial. Note that the open-collector outputs require external pull-up resistors, the value of which should be carefully chosen based on the load and desired switching speed.
