3 Description

The TLV40x1 devices are low-power, high-accuracy

comparators with precision references and fast

response. The comparators are available in an ultrasmall,

DSBGA package measuring 0.73 mm × 0.73

mm, making the TLV40x1 applicable for space-critical

designs like portable or battery-powered electronics

where low-power and fast response to changes in

operating conditions is required.

The factory-trimmed references and precision

hysteresis combine to make the TLV40x1 appropriate

for voltage and current monitoring in harsh, noisy

environments where slow moving input signals must

be converted into clean digital outputs. Similarly, brief

glitches on the input are rejected ensuring stable

output operation without false triggering.

The TLV40x1 are available in multiple configurations

allowing system designers to achieve their desired

output response. For example, the TLV4021 and

TLV4041 offer a non-inverting input, while the

TLV4031 and TLV4051 have an inverting input.

Furthermore, the TLV4021 and TLV4031 feature an

open-drain output stage, while the TLV4041 and

TLV4051 feature a push-pull output stage. Lastly,

each comparator in the TLV40x1 family is available

with a 0.2V, 0.5V, or 1.2V precision reference.
