Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics fully supplies AD4004BCPZ (16-bit, 1 MSPS Pseudo-differential SAR ADC), with ultra-low noise, high reliability and flexible adaptation capability, providing precision data acquisition solutions for industrial automation, medical instruments and communication equipment ‌.

summarize

The AD4004BCPZ is a 16-bit, high precision, high speed, low power pseudo differential successive approximation register analog-to-digital converter (ADC). With a fast suite throughput of up to 1 MSPS, the AD4004BCPZ can accurately capture high-frequency signals and implement oversampling techniques to mitigate the challenges associated with anti-aliasing filter design. In addition, the power consumption of the ADC is linearly related to the throughput.

The AD4004BCPZ uses input range compression to eliminate the negative power requirement on the ADC driver amplifier while preserving the full ADC code range. In addition, the input overclamp protects the ADC input from overvoltage events, minimizes interference to the reference pin, and eliminates the need for an external protection diode.

By reducing Serial Peripheral interface (SPI) clock frequency requirements, the AD4004BCPZ reduces digital input and output power consumption, expands digital host options, and simplifies the task of sending data across digital isolation. By using a separate VIO logic power supply, the SPI-compatible serial user interface supports 1.8V, 2.5V, 3.3V and 5V logic.

Specific parameters of the AD4004BCPZ include:

Package format ‌ : LFCSP-10

Max. analog input voltage ‌ : 5.1V

The longest conversion time ‌ : 0.32μs

Maximum linear error ‌ : 0.0015%
