AD7892ANZ-2

Data Acquisition - Analog to Digital Converters (ADC)

The AD7892ANZ-2 is an Analog to Digital Conversion (ADC) integrated circuit containing precision, low-drift track-and-hold amplifiers, a 6-bit generic ADC, with 10-bit result accuracy, and a voltage reference. This device is designed to provide excellent accuracy, low noise performance and low power consumption while simplifying the end system design. Its small packages, which include TQFP, SOIC, and SSOP, make it ideal for embedded systems requiring low-power, low-cost, and wide-range solutions in both industrial and consumer market applications.

The AD7892ANZ-2 is designed for use whenever digital signals need to be converted from an analog form in order to make them easier to measure, process, or store. This device is ideal for use in a variety of industrial applications, as well as consumer grade gadgets, such as digital cameras and portable media players. It is also suitable for use in medical systems, data acquisition systems, and automotive sensors.

The AD7892ANZ-2 has two inputs, labelled CH0 and CH1, which are each provided with a low-noise, low-drift, Class AB precision amplifier. These amplifiers also limit the amount of noise present on the input signals, and reduce the amount of gain drift due to temperature changes. The integrated ADC has a 6-bit programmable generic resolution, along with a DNL (differential nonlinearity) of 1.5-LSB. The device also has a voltage reference, which is used to compare the analog input signal to a known voltage level, and is used to calibrate the readings and improve accuracy.

In operation, the AD7892ANZ-2 uses a dual-slope conversion technique. The input signal is first amplified and then applied to the A/D converter. The A/D converter then starts a first, timed conversion, and then follows a conversion algorithm which incorporates both positive and negative polarity signals. This allows the device to determine the average of the input voltage, and then adjust the output accordingly. This method of conversion allows for excellent accuracy, and is unaffected by low-frequency noise.

The advantages of the AD7892ANZ-2 include its excellent noise performance, low-drift, low-power consumption, and its small footprint. Its versatility makes it an ideal solution for a wide variety of applications, from industrial to consumer grade. Its wide range of packages make it easy to integrate into existing systems, and provides flexibility for future designs. The dual-slope conversion technique gives excellent accuracy and makes the device immune to many forms of noise.

The AD7892ANZ-2 is an excellent choice for data acquisition applications requiring high accuracy, low-drift, low-power consumption and small size. With its wide range of packages and its ability to use dual-slope conversion, it provides a high-performance, low-cost solution for industrial, consumer, medical and automotive applications.
