LM2202N application field and working principle

The LM2202N is a linear amplifier module from National Semiconductor Corporation designed for video applications. This module is a low-noise, differential, two-stage amplifier designed for operating with 1.4 V DC supply and is supplied in the 14-pin small outline package. The LM2202N has a noise-free performance from 1 MHz up to 4 MHz and can be used as a voltage amplifier and line driver in audio applications.

Features

The LM2202N linear module features include:•Ultra-low noise between 1 and 4 MHz, making it ideal for video applications •Differential inputs with single ended outputs •Offset voltage of 10 mV maximum •Small, surface-mounted package •High performance with low power consumption •Input referred noise of 1.5 nV/√Hz •Low thermal resistance

Application fields

The LM2202N is mainly used in video applications such as television and video game systems, broadcasting, and VCRs. The module is also used in audio amplifiers and line drivers for high-end speakers. The low noise and high performance of the LM2202N makes it ideal for these applications, as it can provide a high-quality signal with minimal distortion.

Working principle

The LM2202N is a two-stage, differential amplifier module consisting of a symmetrical pair of input stages and a single output stage. The first stage of the amplifier is the differential input stage, which consists of two differential NPN transistors. The second stage of the amplifier is the output stage, which consists of a single NPN transistor. This output stage provides a high current drive for the output signal.The LM2202N has a noise-free performance from 1 MHz to 4 MHz, with a low noise floor of 1.5 nV/√Hz and a high slew rate of 15 V/μs, making it ideal for video applications. The input offset voltage of the amplifier is 10 mV maximum, making it suitable for low voltage applications. The LM2202N is also supplied in a small, surface-mount package and is capable of high performance at low power consumption.
