# Linear Integrated Circuit Questions and Answers – Integrated Circuit Package Type, Pin Configuration and Temperature Range – 1

This set of Linear Integrated Circuit Multiple Choice Questions & Answers (MCQs) focuses on “Integrated Circuit Package Type, Pin Configuration and Temperature Range – 1”.

1. Miniaturization of components with superior performance can be obtained in
a) Integrated circuits
b) Discrete circuits
c) Both integrated and discrete circuits
d) None of the mentioned

Explanation: All the components in integrated circuits are fabricated on the same chip, whereas in discrete circuits discrete components are used and occupies more area.

2. Why Integrated Circuits are considered to be economical?
a) Simple manufacturing process
b) Provide trouble free service
c) Due to batch production
d) Easy to use and reuse

Explanation: Integrated Circuits are considered to be economical because, it reduces the cost due to batch production. A standard 10cm diameter wafer can be divided into 8000 rectangular chip (approx). So, if 10 wafers are processed in one batch, then 80,000 ICs are produced simultaneously.

3. Which of the following circuit is not made of digital ICs?
a) Shift registers
b) Multipliers
c) Demultiplexers
d) Counters

Explanation: Multipliers are made up of Linear Integrated Circuits.

4. Controlling the characteristics of operating region is not taken care in digital ICs because
a) It involves only two voltages
b) It is used to form transistor logic
c) Digital IC requires only power supply, input and output
d) All of the mentioned

Explanation: Digital circuits are primarily concerned with only two level of voltages (or currents): ‘high’ and ‘low’. Therefore, accurate control of operating region characteristic is not required in digital circuits, unlike in linear circuits.

5. Linear Integrated Circuit can also be called as
a) Monolithic circuit
b) General purpose circuit
c) Special purpose
d) Analog circuit

Explanation: The output electrical signal and the input signal applied in linear circuit vary either in proportion or in physical quantities they represent. Since, the electrical signals are analogous to the physical quantities, linear circuit are also referred to as analog circuit.

6. How are components array available in IC form?
a) Array of silicon wafer
b) Group of isolated transistor, diodes and resistor
c) Array of individual stages of differential and cascade amplifier
d) Group of gates logic circuits arranged in array format

Explanation: Majority of linear ICs are available as operational amplifier. So, these components array consists of group of isolated transistor, diodes and resistors.

7. Which type of integrated circuit is suitable for small quantity custom circuits?
a) Monolithic IC
b) Linear IC
c) Hybrid IC
d) Digital IC

Explanation: In hybrid circuits, separate components parts are attached to a ceramic substrate and interconnected by means of either metallization pattern or wire bond. This technology is adaptable to small quantity custom circuits only.

8. What is the isolation technique used in monolithic IC?
a) PN-junction
b) Dielectric junction
d) All of the mentioned

Explanation: Electrical isolation between the components in monolithic ICs can be achieved by any one of the three isolation techniques dielectric, beam-lead or PN-junction.

9. Monolithic Integrated Circuits exhibits
a) Increase in power consumption
b) Non-matched devices
c) Thermal stability
d) All of the mentioned

Explanation: Monolithic ICs exhibits good thermal stability because all the components are integrated on the same chip very close to each other.

10. How are thin film hybrid ICs obtained?
a) Evaporation method
b) Spraying method
c) Silk screening method

Explanation: In thin film hybrid IC the resistors, capacitors and interconnections are separately formed on the substrate and a suitable material is evaporated on the substrate to make connection.

11. Which of the following belongs to special purpose op-amp?
a) LM741
b) LM380
c) IC351
d) None of the mentioned

Explanation: LM380 is a special purpose op-amp, used only for audio power application.

12. How many op-amps will be present in a typical op-amp package?
a) Three
b) Four
c) Five
d) Nine

Explanation: Op-amp package IC consists of single, dual (two) or Four (quad) op-amps.
