TLV40x1 Small-Size, Low-Power Comparator with Precision Reference
1 Features
3 Description
The TLV40x1 devices are low-power, high-accuracy
comparators with precision references and fast
response. The comparators are available in an ultra-
small, 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.
Non-inverting and inverting input options
Precision hysteresis
Temperature range: –40°C to +125°C
Packages:
The TLV40x1 are available in multiple configurations
allowing system designers to achieve their desired
output response. For example, the TLV4021 and

0.73 mm × 0.73 mm DSBGA (4-bump)
SOT-23 (5-pin)
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.
