AD7893ACHIPS-10 is an analog-to-digital converter (ADC) designed to convert analog input voltages to digital output codes. It is a single, low-power CMOS device that incorporates a 10-bit charge-balancing successive approximation ADC, an input amplifier, and a 2.7V to 5.5V analog reference. The part has a power supply range from 2.7V to 5.5V and is packaged in a space-saving SOIC-10 package.

The AD7893ACHIPS-10 is ideal for use in many industrial applications, including AC current and voltage measurements, temperature sensing, strain gauge measurements, automotive power sensing and control, medical instrumentation systems, environmental monitoring systems, and instrumentation for measuring and monitoring medical and environmental conditions. The AD7893ACHIPS-10 is also very suitable for these scenarios and can greatly improved signal-to-noise ratio, most conversions are faster, and less power is consumed.

The working principle of the AD7893ACHIPS-10 is based on the successive approximation method. Using this approach, the input analog voltage is compared to a series of reference voltages (starting with the midpoint of the input voltage range). Digits are then shifted in one-at-a-time, with the high digit going first. When a comparison is made, a “1” is output if a reference voltage used is higher than the input voltage and a “0” is output if the reference voltage is lower than the input voltage. This process is continued until all 10 bits have been shifted and the output code is obtained.

The AD7893ACHIPS-10 offers a range of features to improve accuracy and reduce system errors, such as its high-speed, low-power architecture, 10-bit SAR architecture, low-power stand-by power mode, and reduced system thermal errors. Additionally, the part is designed to operate over an extended temperature range of -40°C to +85°C. Other features of the device include its single +2.7V to +5.5V supply voltage, on-chip input amplifier, programmable chopping and offset compensation, selectable reference voltage, and asynchronous/synchronous interface mode.

The AD7893ACHIPS-10 is a versatile analog-to-digital converter that offers features such as high-speed, low-power operation, 10-bit SAR architecture, low-power stand-by power mode, and reduced system thermal errors.
