+### Typical Application
21
+
22
+A common application for an operational amplifier is an inverting amplifier. This amplifier takes a positive voltage on the input, and produces a negative voltage with the same magnitude.
23
+
24
+In the same manner, the amplifier also makes negative voltages positive. A linear gain can be achieved by changing the resistor ratio in the feedback path.

93
+## LM358 Common-Mode Input Voltage Range
94
+
95
+Single Supply Opamp has only one supply rail (+VCC) to an opamp for which your applied signal will be amplified or swing only in between the +VCC and GND.Therefore, your output voltage has a swing in between +VCC and GND rails.
96
+
97
+Dual Supply opamp has two supply rails with reference to GND to an opamp i.e +VCC and -VCC rails.Your applied voltage can swing between these two voltage levels.Hence, the output signal can swing only between these voltage(+VCC and -VCC) limits and they cannot exceed above these levels.
98
+
99
+For example, in an audio signal amplification, the input audio signal(Voice) can swing between +ve and -ve voltage levels(usually in mV). So this input signal can be amplified to +12V(+VCC) and -12V(-VCC) if your apply the +VCC=12V and -VCC=-12V.
100
+
101
+#### **Single-Supply Operation (e.g., 0V to 5V)**
102
+- **CMVR:** 0V to (Vcc - 1.5V)
103
+- Example: If **Vcc = 5V**, input range is **0V to 3.5V**.
104
+
105
+#### **Dual-Supply Operation (e.g., ±5V)**
106
+- **CMVR:** (V−) to (V+ - 1.5V)
107
+- Example: If **Vcc = ±5V**, input range is **-5V to +3.5V**.
108
+
109
+#### **Key Considerations**
110
+- **Input must stay within CMVR** for proper operation.
111
+- **Exceeding CMVR** may cause distortion or incorrect behavior.
112
+- **LM358 supports input down to ground** (0V) in single-supply mode.

143
+### LM358 for Shock Alarm Circuit:
144
+A shock alarm circuit similar to the one below can be found in both homes and cars. Its major use is as an anti-theft alarm in autos. The shock sensor in this circuit is a piezoelectric sensor, which needs to be mounted on the door you wish to protect. The LM358 is attached in this instance as an inverting Schmitt trigger. Port 1 can set the circuit's threshold voltage, and resistor R1 serves as a feedback resistor.
145
+
146
+
147
+The piezo sensor will have a low output when it is not active. The buzzer is activated when the Schmitt trigger is triggered by the piezo sensor's high output. It takes some time for the buzzer to stop beeping even if the vibration is disconnected. This happens because the state is difficult to invert and the inverting input, as it grows, has less of an impact once the LM358 IC is turned on.

-### Typical Application
21
-
22
-A common application for an operational amplifier is an inverting amplifier. This amplifier takes a positive voltage on the input, and produces a negative voltage with the same magnitude.
23
-
24
-In the same manner, the amplifier also makes negative voltages positive. A linear gain can be achieved by changing the resistor ratio in the feedback path.

-## LM358 Common-Mode Input Voltage Range
94
-
95
-Single Supply Opamp has only one supply rail (+VCC) to an opamp for which your applied signal will be amplified or swing only in between the +VCC and GND.Therefore, your output voltage has a swing in between +VCC and GND rails.
96
-
97
-Dual Supply opamp has two supply rails with reference to GND to an opamp i.e +VCC and -VCC rails.Your applied voltage can swing between these two voltage levels.Hence, the output signal can swing only between these voltage(+VCC and -VCC) limits and they cannot exceed above these levels.
98
-
99
-For example, in an audio signal amplification, the input audio signal(Voice) can swing between +ve and -ve voltage levels(usually in mV). So this input signal can be amplified to +12V(+VCC) and -12V(-VCC) if your apply the +VCC=12V and -VCC=-12V.

101
-#### **Single-Supply Operation (e.g., 0V to 5V)**
102
-- **CMVR:** 0V to (Vcc - 1.5V)
103
-- Example: If **Vcc = 5V**, input range is **0V to 3.5V**.
104
-
105
-#### **Dual-Supply Operation (e.g., ±5V)**
106
-- **CMVR:** (V−) to (V+ - 1.5V)
107
-- Example: If **Vcc = ±5V**, input range is **-5V to +3.5V**.
108
-
109
-#### **Key Considerations**
110
-- **Input must stay within CMVR** for proper operation.
111
-- **Exceeding CMVR** may cause distortion or incorrect behavior.
112
-- **LM358 supports input down to ground** (0V) in single-supply mode.

-**The gain is -R5/R2** only when the gain is defined as the output voltage divided by the voltage at the R2/C1 junction.
127
-
128
-The gain from the source -- the MIC -- on the other side of C1 is influenced by the impedance of C1.
129
-
130
-compared to 20kHz, at 1.6kHz the gain has fallen to ~70% x (-R5/R2).

-### LM358 for Shock Alarm Circuit:
144
-A shock alarm circuit similar to the one below can be found in both homes and cars. Its major use is as an anti-theft alarm in autos. The shock sensor in this circuit is a piezoelectric sensor, which needs to be mounted on the door you wish to protect. The LM358 is attached in this instance as an inverting Schmitt trigger. Port 1 can set the circuit's threshold voltage, and resistor R1 serves as a feedback resistor.
145
-
146
-
147
-The piezo sensor will have a low output when it is not active. The buzzer is activated when the Schmitt trigger is triggered by the piezo sensor's high output. It takes some time for the buzzer to stop beeping even if the vibration is disconnected. This happens because the state is difficult to invert and the inverting input, as it grows, has less of an impact once the LM358 IC is turned on.
