Working Principles

The PCM1800E/2KG4 operates on the principle of delta-sigma modulation. It converts analog audio signals into a digital format by oversampling the input signal and using a sigma-delta modulator to encode the signal as a stream of 1s and 0s. The oversampling and noise shaping techniques employed by the converter result in high-resolution and low-distortion digital audio output.

Application Field Plans

The PCM1800E/2KG4 is widely used in various audio applications, including:

1. Professional audio recording equipment
2. Consumer audio devices such as CD players and home theater systems
3. Musical instruments and synthesizers
4. Automotive audio systems
5. Telecommunications equipment

Alternative Models

Here are some alternative models that provide similar functionality:

1. PCM1800E/2K: Similar specifications and package, but without the extended temperature range.
2. PCM1800E/1KG4: Lower quantity packaging option with 1000 units per reel.
3. PCM1800E/3KG4: Higher quantity packaging option with 3000 units per reel.

These alternative models can be considered based on specific project requirements and volume needs.
