PCM1723E is a multi-channel stereo differential input, delta-sigma modulator specifically designed for audio applications. It is part of Texas Instruments’ advanced analog-to-digital converter (ADC) family, which includes automotive-grade products, ultra-low power audio ADCs, and multi-channel digital input ADCs. PCM1723E has excellent high-frequency performance, high dynamic range (116 dB), and is designed to provide high-performance audio conversions and improved audio performance. It is ideal for digital audio converters, mixing consoles, and several other high-end audio applications.

Overview of PCM1723E

PCM1723E operates in asynchronous sampling mode, which requires an external oscillator. This feature minimizes the power consumption of the device. The conversion rate is programmable usually up to 192K sample.It has programmable anti-alias filters with filter rolls-off of up to -96 dB. It also has five power modes that are optimized for different types of systems. The five power modes are normal, low power idle, low power standby, high power standby, and power-down.

PCM1723E supports several control and programming modes. It supports direct bus interface, three-wire serial bus, and I2C control. Its programming registers contain all of the commands and settings needed for the various operations and features. These registers allow users to configure the power modes, sampling rate, gain, filter settings, etc.

Applications of PCM1723E

PCM1723E is widely used in audio applications due to its excellent performance. It is perfect for digital consoles, mixers, and similar devices where high-accuracy audio conversions are required. It is also used in high-end audio equipment such as digital amplifiers, DACs, power amplifiers, and speakers.

It is also used in automotive audio systems, digital receivers, and multimedia systems. This multi-channel device makes it possible to have multiple channels of the same type, each with its own DAC and anti-alias filtering. This allows for more realistic sound reproduction and improved audio quality overall.

PCM1723E is also used in medical applications, such as hearing aids and medical sensors. It has a fast response time and very low distortion, making it perfect for applications where audio accuracy and clarity need to be maintained.

Working Principle of PCM1723E

PCM1723E uses differential delta-sigma modulators to convert an analog signal into a digital output. The device starts by examining the analog signal, comparing it to an internal reference voltage. The resulting differences are measured by the PCM1723E, which then converts the data into digital output. This is done via a process of sampling, quantization, and then digital output.

The device works by computing a digital sum of the differences between the input and an internal reference voltage. This sum is used to provide an accurate digital representation of the original analog signal.

The PCM1723E also implements advanced digital filters and multi-channel capabilities, making this device ideal for applications that require high audio performance. It has very good SNR, THD, and dynamic range, allowing for improved audio quality without added distortion.
