Dual comparator with integrated reference

09-07-2020 | Texas Instruments | Semiconductors

The Texas Instruments TLV4062 and TLV4082 are a family of high-accuracy, dual-channel comparators providing low power and small solution size. The IN1 and IN2 inputs comprise hysteresis to reject brief glitches, thus ensuring stable output operation with no false triggering.

The comparators provide adjustable INx inputs that can be configured by an external resistor divider pair. When the voltage at the IN1 or IN2 input drops below the falling threshold, OUT1 or OUT2 is driven low, respectively. When IN1 or IN2 increases above the rising threshold, OUT1 or OUT2 goes high, respectively.

The comparators provide a very low quiescent current of 2µA (typical) and offer a precise, space-conscious solution for low-power, voltage monitoring. The devices operate from 1.5V to 5.5V, over the –40C to +125C temperature range.
