Texas Instruments TLV40x1 Low-Power Comparators
Texas Instruments TLV40x1 Low-Power Comparators are low-power, high-accuracy comparators with precision thresholds and a propagation delay of 360ns. These comparators are available in an ultra-small, DSBGA package measuring 0.73mm×0.73mm. This feature makes the TLV40x1 applicable for space-critical designs like portable or battery-powered electronics where low-power and fast response to changes in operating conditions are required. The factory-trimmed switching thresholds and precision hysteresis combine to make the TLV40x1 appropriate for voltage and current monitoring in harsh, noisy environments. These devices are ideal where slow-moving input signals must be converted into clean digital outputs. Similarly, brief input glitches are rejected, ensuring stable output operation without false triggering.The Texas Instruments TLV40x1R1/2 are available in multiple configurations, allowing system designers to achieve the desired output response. For example, the TLV4021 and TLV4031 feature an open-drain output stage, while the TLV4041 and TLV4051 feature a push-pull output stage. Furthermore, the TLV4021 and TLV4041 offer a non-inverting input, while the TLV4031 and TLV4051 have an inverting input.
