SGM8709
Micro-Power, CMOS Input, RRIO, 1.4V,
Open-Drain Output Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8709 is a single, rail-to-rail input CMOS
comparator with typical 318nA ultra-low power supply
current. The comparator operates from a wide range of
1.4V to 5.5V supply voltage, and is guaranteed to
operate at 1.4V, 2.5V and 5.0V. This feature is suitable
for battery-powered applications.
● Ultra-Low Quiescent Current:
318nA (TYP) at VS = 1.4V
● Wide Single-Supply Voltage Range: 1.4V to 5.5V
● Typical 6μs Propagation Delay at VS = 1.4V
● Rail-to-Rail Input and Output
● N-MOSFET Open Drain Output Structure
● Open Drain Output Current Drive:
18.7mA (TYP) at VS = 5V
The SGM8709 is optimized for micro-power, single-supply
operation. The open-drain output stage allows for
operation with absolute minimum power consumption
when driving any capacitive or resistive load.
● -40℃ to +85℃ Operating Temperature Range
● Available in Green SOT-23-5 and SC70-5 Packages
APPLICATIONS
The SGM8709 is available in Green SOT-23-5 and
SC70-5 space-saving packages. The small packages
make this device ideal for use in hand-held electronics
and mobile phone applications. It is rated over the
-40°C to +85°C temperature range.
