TP1941/TP1941N/TP1942/TP1944
68ns, 1.8V, Ultra-low Power, RRI, Push-Pull Output Comparators
Features
Description
The 3PEAK INCORPORATED TP194x families of
CMOS/TTL compatible comparators are offered in
single, dual, and quad configurations, and are
exceptionally versatile and easy to use.
Fast Response Time: 68 ns Propagation Delay
Ultra-Low Supply Current: 46 μA per Channel
Offset Voltage: ± 3.0 mV Maximum
The TP194x incorporate 3PEAK’s proprietary and
patented design techniques to achieve the ultimate
combination of high-speed (68ns propagation delay
under 1.8~5.5V wide supply range) and low power
consuming (46μA quiescent current per comparator).
These comparators are optimized for low power
1.8V, single-supply applications with greater than
rail-to-rail input operation, and also operate with
±0.9V to ±2.75V dual supplies. The input common
mode voltage range extends 200mV below ground
and 200mV above supply, allowing both ground and
supply sensing. The internal input hysteresis
eliminates output switching due to internal input
noise voltage, reducing current draw. The push-pull
output supports rail-to-rail output swing, and
interfaces with CMOS/TTL logic. The output toggle
frequency can reach a typical of 4 MHz while limiting
supply current surges and dynamic power
consumption during switching.
Offset Voltage Temperature Drift: 0.3 μV/°C
Input Bias Current: 6 pA Typical

Window Comparators
The TP1941 single comparators are available in
shout-down function, output latch version, and the
tiny SC70/SOT23 package for space-conservative
designs. All devices are specified for the
temperature range of –40°C to +85°C.
