Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. The process of measuring a signal\'s electric potential as a numerical value is known as Analog to Digital Converters (ADC). The MAX1246BEEE is a high-precision, low-power, wide-temperature-range, 16-bit Analog-to-Digital Converter (ADC). The device operates in single-supply or dual-supply operation, with full-scale input ranges from 5V to 3V, or from 4V to 3V respectively.

The MAX1246BEEE is built on a fast 8-channel capacitive successive approximation register (CSAR) analog-to-digital converter (ADC) core and a precision delta-sigma modulator. The device offers 14-bit no missing codes and 16-bit linearity over its full temperature range, and converts analog signals in single-ended mode to 16-bit serial data output with a maximum sampling rate of 32ksps (kHz per second). Its small package size and two-channel mode operation make it ideal for industrial and automotive applications.

The high temperature range of the MAX1246BEEE makes it well suited for automotive, industrial and medical applications. The device is also very power efficient, consuming less than 15mW per channel in single-supply, or 28mW per channel in dual-supply. It has a small 8#-pin VSSOP package and is also available in a 10#-pin SOIC package.

The MAX1246BEEE has several programmable features that allow it to be tailored to best suit a specific application. These include a reference adjustment and temperature compensation for the SAR core, allowing for a wide input dynamic range, programmable data output format, sample rate and internal and external synchronization, field selectable conversion rates, and selectable analog and digital common-mode levels.

The working principle of the MAX1246BEEE is based on the capacitive SAR ADC architecture. A resistor network provides a scaled voltage to the device\'s differential analog inputs, which is then digitized by the SAR core. The SAR core consists of a charge redistribution capacitor array, a pseudo-dynamic latch array and a digital control unit. The device also includes a low-noise, low-power delta-sigma modulator for added accuracy.

The device utilizes a SAR comparator with a selectable compare voltage range to provide a precise digital output. The output data format is selectable between left justified and right justified, with a user-defined offset and gain applied to the data. The modulator is used to DAC the 16-bit SAR output and the added gain, offset and temperature calibration is applied to improve the overall system accuracy.

In summary, the MAX1246BEEE is a high-performance, low-power, wide-temperature-range, 16-bit Analog-to-Digital Converter. It is well suited for industrial, automotive and medical applications and its small size, power efficiency and programmable features make it ideally suited for a wide range of data acquisition applications.
