The AD8285WBCPZ is a high-performance, low-power, single-channel, audio-enable analog-to-digital converter (ADC). It is ideal for audio-enabled applications for both computer and consumer electronics markets. The AD8285WBCPZ features an advanced CMOS imaging technology, allowing it to achieve a 12-bit resolution with a noise-free dynamic range up to 85dB. The AD8285WBCPZ can operate in the range of 2.4MHz to 24MHz.

The AD8285WBCPZ is suitable for applications that require a wide dynamic range. It can be used to support audio-enabled applications in digital still cameras, projectors, television sets, HDTVs, and other audio and/or digital video products. Additionally, the device can be used in digital music players, portable media players, digital audio players, and other audio devices.

The AD8285WBCPZ is designed to operate at ±5V on a single supply. It is available in 7-pin and 10-pin packages. The AD8285WBCPZ supports a differential analog input that ranges from 0V to 0.8V (full-scale). It also has an adjustable built-in reference voltage of 1V to 5V, allowing it to operate more than 80 percent of the input signal range. A low-power shutdown mode is also provided, reducing power consumption to a minimum of 1µA.

The AD8285WBCPZ is capable of producing a digital output that can be easily read by a controller. It also includes an internal oscillator that is compatible with a 4MHz to 24MHz clock, as well as an optional external clock. An optional digital input is available, allowing the user to precisely control the converter’s digital output. In addition, the AD8285WBCPZ supports an asynchronous signal reset signal, allowing the user to reset the device at any time.

In terms of its working principle, the AD8285WBCPZ uses a capacitor-based capacitive-to-digital converter (CDC) topology to convert analog input signals to a digital form. This is accomplished using a chain of cascaded capacitors that operate in tandem with a series of switching elements. As the signals are converted, the circuit generates a series of digital outputs corresponding to the input signal’s amplitude. The outputs of this device are then processed using a two\'s complement digital signal processing (DSP) algorithm to obtain a 12-bit linear output code.

The AD8285WBCPZ is a versatile, high-performance, high-precision, low-power, single-channel analog-to-digital converter suitable for audio-enabled applications. Its wide dynamic range and adjustable internal reference voltage make it a perfect choice for digital still cameras, projectors, television sets, HDTVs, as well as digital music players, portable media players, and other audio devices.
