TLV1872
- Wide supply range: 2.7V to 40V (±1.35V to ±20V)
- 65ns propagation delay
- Single or split supplies operation
- "Floating" push-pull output with separate supplies
- Rail-to-rail input
- Power-on-reset (POR)
- Low supply current: 75µA per channel
- Temperature range: -40°C to +125°C
The TLV187x is a 40V high-speed comparator family that offers rail-to-rail inputs and a push-pull output-stage with separate input and output supply pins. These features coupled with 65ns propagation delay make this family well-suited for bipolar zero-cross detection, Class D audio amplifier systems, and other applications where level translation and propagation delay symmetry is needed.
This device includes a Power-On Reset (POR) feature that holds the output in a known state until the minimum supply voltage has been reached before the output responds to the inputs, thus preventing false outputs during system power-up and power-down.
The TLV187x has a push-pull output stage, making them an excellent choice for applications where symmetry between rising and falling output responses is desired. This device offers the ability to level translate for downstream devices at lower voltages due to the separate input and output supplies.
