LM1875 amplifier circuit 30 watts
The LM1875 ("eighteen-seventy-five") is a monster of a chip in a very unassuming package, and another much-loved chip in the DIY audio community. The official datasheet (PDF) claims the ability to drive 20W into 8Ω loads given +-25V, and up to 30W supplied with an extra +-5V of juice. and all at less than 1% THD. Build a High Quality Audio Amplifier with the LM1875 Posted by Graham Lambert | DIY Electronics | 1 In a previous article, we looked at the design of transistor amplifiers. Here, we are going to put together the building blocks of an IC-based audio amplifier. Step 1: Schematics and Parts As the schematics of the amplifier and power supply circuits in the Elliott Sound Products webpage, it's not a complex amplifier as seen in the drawings above. With LM1875 and several common RLC components, you can easily make the power amplifier by yourself. Here's LM1875, at low cost, and easily made by following the "play by play" photographic format (starting at post#24). The LM1875's "only 5 pins hookup," and the absence of spike system noise, can give you 25 watts per channel of high fidelity, at a bargain price, and with an easy time of building your own amplifier.
LM1875 A Comprehensive Guide on Audio Amplification
Understanding the LM1875. This amp is in fact a power opamp with open loop frequency of 70hz and 90db gain. This is measured with 2k load. If the output is a tranconductance amplifier as I can guess from the internal circuit, than the OLG/BW depend upon the load. This is not specified but what betrays is the need of output snubber to limit the. This subwoofer amplifier circuit consists of a TL072 low-noise JFET dual operational amplifier (IC1) and two LM1875 (IC2 and IC3) power amplifiers. Circuit operation In stereo mode, each half of the TL072 operates as a non-inverting input amplifier, with a gain of about 2.8 times as determined by feedback resistors R5 and R6. The LM1875 is a wide power amplifier with very low distortion and high-quality efficiency for audio applications. It gives power is 20 watts into a 4 ohms or 8 ohms load on 25V power supplies. Its amplifiers circuits are designed to working with a minimum of external parts. DESCRIPTION The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. The LM1875 delivers 20 watts into a 4Ω or 8Ω load on ±25V supplies. Using an 8Ω load and ±30V supplies, over 30 watts of power may be delivered.
10Watt Audio Amplifier Circuit LM1875
The circuit diagram of the audio amplifier is shown in Fig. 2. It is built around popular amplifier LM1875 (IC1), an 8-ohm, 10-watt speaker (LS1) and a few other components. Connect the audio input from your mobile/laptop/PC to CON1. Connect 15V battery and switch on S1. You should hear amplified sound in speaker LS1. The thermal resistance junction - case is 3C/W. The gain product bandwidth of the IC is typically 5.5MHz. The typical slew rate of LM1875 is 8V/us. The maximal output power of the IC is typically 25W over load of 8Ohm at power supply of +-25V. LM1875 Based Simple Amplifier. Figure 1 is showing the circuit of the LM1875 based simple amplifier.
LM1875 is a monolithic power amplifier IC from Texas Instruments with five terminals. It can function in a dual rail or single rail power supply and has built-in protection that ensures its durability. Further, it uses a few external components to operate in applications like high-power audio amplifier designs. LM1875 Pin Configuration Supply Voltage: 12-36VDC Power Output: 14W TDA2050 Supply voltage: 4.5-25VDC Power Output: 32W / 50W Music Power LM1875 Supply voltage: 16-60VDC Power Output: 30W
