SGM8140
Low Power, Vibration Sensor and
PIR Sensor Analog Front End (AFE)
GENERAL DESCRIPTION
FEATURES
The SGM8140 is a PIR sensor and vibration sensor
analog front end which consists of 2 independent
building block circuits. One is a dual rail-to-rail input
and output operational amplifier, and the other is an
ultra-low power comparator. Both the operational
amplifier and the comparator have been specifically
designed to operate over a wide range of voltages from
1.4V to 5.5V. The SGM8140 only consumes 1.1μA
working current, so it is ideal for use in a variety of
battery-powered applications.
● Ultra-Low Power: 1.1μA (TYP) at VS = 5V
● Wide Supply Voltage Range: 1.4V to 5.5V
● Rail-to-Rail Input and Output Amplifier
● Amplifier Gain-Bandwidth Product:
5kHz (TYP) at VS = 5V
● Amplifier is Unity-Gain Stable
● Comparator Propagation Delay: 6μs (TYP)
● Comparator Push-Pull Output Current Drive:
19mA (TYP) at VS = 5V
● -40℃ to +85℃ Operating Temperature Range
● Available in a Green TQFN-4×4-16L Package
The operational amplifier is unity-gain stable and
features a 5kHz gain-bandwidth product. It is suitable
for low frequency systems in the case of monitoring
battery current and conditioning sensor signal.
APPLICATIONS
Toll Booth Tags
Wearable Products
The comparator has a push-pull output, which drive
resistive or capacitive with absolute lowest power
consumption.

Vibration Detectors
The SGM8140 is available in a Green TQFN-4×4-16L
package. It is specified for the -40 ℃ to +85 ℃
industrial temperature range.

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

DISCLAIMER
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
