Description:

The LM-358 consists of two high-gain frequency-adjusted operational amplifiers. They are designed to operate from a single supply or split sources over a wide voltage range. The LM-358 includes a range of notable features such as wide supply ranges, low supply current drain, supply voltage independence, wide unity gain bandwidth, ground common mode input voltage range, low input bias, open-loop differential voltage gain, and internal frequency correction. The LM-358 has several practical applications, including operational amplifier (Op-amp) circuits, transducer amplifiers, DC gain blocks, and more.

Principle of Work:

Op-amps are multistage amplifiers with intricate connections between their various amplifier stages, comprising many transistors, FETs, and resistors. These components occupy little space, making it available in the form of an Integrated Circuit (IC) packaged in a compact box. An operational amplifier can be set up to perform various operations, such as amplification, subtraction, differentiation, addition, and integration. The op-amp has two input terminals and one output terminal, along with two voltage supply terminals. The differential input consists of two input terminals: the inverting terminal (-) and the non-inverting terminal (+). If an input signal is supplied to the inverting terminal (-), the amplified output will be 180 degrees out of phase with the input signal. Conversely, applying an input signal to the non-inverting terminal (+) will result in an output signal in phase with the input.

Pin 8 is the power supply input for the LM358. The input voltage range for the LM358 comparator is 3 to 32 volts. The supply voltage range for the LM358 when used as an operational amplifier is 1.5V to 16V. The LM358 has two operational amplifiers (A and B). The inputs for the first amplifier (A) are pins 2 and 3, with the output at pin 1. The input and output of the second amplifier (B) are at pins 5 and 7, respectively, if used.

How to make an IR Proximity sensor with LM358

Components Used:

• LM358

• 10K ohm Resistor

• 220-ohm Resistor

• IR transmitter LED

• IR receiver LED

• Colored LED

• 5V Battery

• 10K ohm variable resistor

The photodiode and infrared LED are connected in parallel and function as a transmitter and receiver, respectively. The photodiode is connected in reverse bias. When an obstruction blocks the IR LED’s emitted light, the light is reflected back and intercepted by the photodiode. The reflected rays reduce the photodiode's resistance, leading to the creation of charge carriers and an electrical signal.

Comparisons:

The LM358 comes in a DIP-8 package, which is smaller than the DIP-14 package of the LM324. This is the primary difference in specifications. The LM324 can dissipate more power than the LM358 due to its larger package size. This could be the reason for the increased offset voltage drift in the LM324.

Comparing the LM741 and LM358, the LM741 requires both positive and negative supplies, while the LM358 supports single-supply operation. The LM358 allows the input to drop to 0V with a single-ended supply of 30V, while the LM741’s input range is limited to ±13V with a ±15V supply.
