TLC320AD50IDW

The TLC320AD50IDW is a monolithic integrated circuit from Stereo Analog Devices Inc. The device is designed to be used in consumer and professional audio applications like digital interface for compact disk (CD) players, tape transports and soundcards. The encoding and decoding of digital audio signals requires the use of special circuits, known as a codec. The TLC320AD50IDW is a digital/analog converter that can also perform the functions of companding (or compressing and expanding of a signal to improve the dynamic range) and sample-and-hold. This makes it an ideal choice for recording, playback and transmission of digital audio signals.

The TLC320AD50IDW has a low power consumption rating and a frequency response of 20 kHz at a resolution of 8 bits in a single supply operation. It is a three-channel codec and comes in a 20-pin plastic dip or thin shrink small outline packages.

Working principle: The TLC320AD50IDW operates in three modes: Analog to Digital conversion and Digital to Analog conversion. It first converts the incoming analog signal into a digital signal and then performs companding (or compressing and expanding of the signal to improve dynamic range). The signal is then transferred to a digital interface like a compact disk (CD) player or a tape transport for recording.

When used in two-channel recording, the codec performs two functions: signal conversion from analog to digital and digital to analog; and companding (or compressing and expansion of the incoming signal to improve the dynamic range). This can be done in both simultaneous (two-channel) and non-simultaneous (one-channel) recording.

The TLC320AD50IDW is also able to perform sample-and-hold operations. This uses a time-shared ADC architecture to sample the input signal at a particular rate and accuracy. The device can be configured to run at sampling rates of 8 kHz to 48 kHz and is suitable for CD players and other applications.

In conclusion, the TLC320AD50IDW is an effective codec providing high fidelity, low power and excellent signal to noise ratio. It has proven ideal for consumer and professional audio applications requiring digital interface such as CD players, tape transports and soundcards.
