21ic News Recently, Texas Instruments has introduced six high-performance audio analog-to-digital converter (ADC) products. Featuring a dynamic range of up to 110dB, these devices in the PCM1865 family integrate features common to portable audio codecs, while also providing designers with a single-function, professional audio ADC. Performance level.

The PCM1865 audio ADC is powered from a single 3.3V supply, eliminating the traditional need for dedicated analog 5V rails, making these products as compact and efficient as possible. Each of the new series addresses many system-level design challenges, including low frequency and ground noise, input signal level sensitivity, and attenuation, and any of this family of products addresses these challenges. . The integrated features of the launch are particularly useful for end devices such as personal computers, sound bar speakers, audio docks, Bluetooth® speakers, video security systems, and automotive entertainment system devices, including car audio mainframes, amplifiers, and active noise. Eliminate the system.

The main advantages of the PCM1865 series:

ï‚· Design Flexibility: The PCM1865 family consists of six pin-to-pin compatible products that provide two-channel and four-channel options through software and hardware controlled variables.

ï‚· High dynamic range: Three of the six PCM1865 series products can achieve up to 110dB performance. There is currently no audio ADC on the market that can achieve a performance rating of 110dB with a single 3.3V supply.

ï‚· Improved signal-to-noise ratio (SNR): Supported by direct, high-voltage 2.1 VRMS, these devices optimize audio quality and achieve higher signal-to-noise ratio (SNR). In addition, the automatic clipping suppression feature of software-controlled devices helps designers optimize input sensitivity at maximum signal-to-noise ratio (SNR).

ï‚· Reduce system complexity: The new audio ADC can provide the same performance as competing solutions with up to 20 components. They integrate a clock-generated phase-locked loop (PLL), a programmable gain amplifier, and a general-purpose front end that supports multiple inputs from a low-level microphone input to a 4.2 VRMS differential input. Designers can easily configure single-ended and differential inputs to eliminate low frequency and ground noise.

ï‚· Helps meet mandatory low-power standby requirements: Integrating TI's patent-pending Energysense technology can help designers meet operational requirements set by the European Ecodesign Directive. By using an on-chip auxiliary ADC, designers can easily set sleep and wake-up thresholds to help devices achieve the energy efficiency levels required by EU design directives.

ï‚· Small form factor for space-constrained applications: These devices are 45% smaller than the same type of device due to the 7.8mm x 4.4mm Thin Small Outline (TSSOP) package.

Tools and support for getting started with design

Designers can begin development of the PCM1865 family using an easy-to-use evaluation module (EVM) including the PCM1865EVM.

There is support in the Texas Instruments Online Support Community Audio Forum, where engineers can search for solutions, get help, and share knowledge and solve problems with peer engineers and TI experts.

Package, supply

Each device in the PCM1865 family is available in a 30-pin TSSOP package. The following table contains information about each device.


Scooter car also called body car, camera car, balance car etc, and the Scooter Adapter is the important accessory for the scooter car. Yidashun can offer the scooter Adapter from 12V to 48V, such as 12V 8A, 15V 5A, 24V 4A, 36V 2A, 42V 2A and 48V 2A and so on.

Yidashun's electric scooter charger have the advantage of Over-current protection, over-voltage protection, over-temperature protection, under-voltage protection, short-circuit protection, anti-backflow, and automatic shut-off protection etc, to ensure the safety during using.
