Description

LS2822 is a bipolar linear integrated circuit designed for the audio power amplifier output section of portable recorders and radios.
This is designed to amplify audio signals, typically from line-level sources or low-power audio sources such as MP3 players or smartphones. It can provide sufficient power to drive speakers and produce audible sound. It is designed to minimize distortion in the amplified audio signal, ensuring clean and accurate sound reproduction. Low distortion helps maintain the fidelity of the original audio signal.

Features

1. Available in dual channel or bridge connection mode

2. Few peripheral components

3. It can still work normally when the power supply voltage drops to 1.8V

4. High channel separation

5. Small crossover distortion

6. Small quiescent current

7. No impact noise when turning on and off

8. Soft clipping

Pinouts

Applications

1. Audio amplification for high-quality sound reproduction

HRM3800 is an electronic component used to receive and decode IR signals transmitted by remote controls.

Function: Photo Module for infrared remote control systems

Package: 3 Pin type

Manufacturer: AZ Display

Description

HRM3800 is miniaturized receiver for infrared remote control systems. PIN diode and preamplifier is assenmbled on lead frame. The demoduolated output signal can be decoded directlyby a microprocessor.

1. The photo module consists of a photodetector, usually a photodiode or phototransistor, which detects infrared light signals emitted by the remote control.

2. The IR receiver module demodulates the received IR signal, extracting the encoded data transmitted by the remote control. This demodulation process may involve filtering and amplifying the received signal to recover the original data.

Features

1. High Reliability

2. Inner shield for good anti-interference ability

3.Low Power Consumption, only 5V supply voltage

4. High Sensitivity, large transmission range

Pinouts

Maximum Ratings

1. Supply Voltage (VS) = 6.0V

2. Operating Temperature Range (Tamb) = -25 to + 85°C

3. Storage Temperature (TSTG) = -25 to + 85°C

4. Soldering Temperature (TSOL)= 260°C
