3 Description

The TLV3201 and TLV3202 are single- and dual-
channel
comparators
combination of high speed (40 ns) and low-power
consumption (40 µA), all in extremely small packages
with features such as rail-to-rail inputs, low offset
voltage (1 mV), and large output drive current. The
devices are also very easy to implement in a wide
variety of applications where response time is critical.
The TLV320x family is available in single (TLV3201)
and dual (TLV3202) channel versions, both with
push-pull outputs. The TLV3201 is available in 5-pin
SOT-23 and 5-pin SC70 packages. The TLV3202 is
available in 8-pin SOIC and 8-pin VSSOP packages.
All devices are specified for operation across the
expanded industrial temperature range of –40°C to
125°C.
