Data Acquisition – Analog to Digital Converters (ADC) is a process for converting analog signals into digital signals. Such conversions are necessary for digital systems which can only process digital data. The MAX1115EKA+T (A + T) is an integrated circuit (IC) designed to enable analog signals to be accurately digitized and converted into digital signals.

The MAX1115EKA+T utilizes an integrated temperature sensor that allows it to capture and convert temperature data. The MAX1115EKA+T IC provides a higher resolution than the standard analog-to-digital conversion and enables the isolation of temperatures to more detailed sub-degree measures. It is built with an on-chip comparator that can measure up to 15-bit resolution, allowing for a higher degree of accuracy.

The MAX1115EKA+T employs a low-power analog-to-digital technique which features a wide-range of input voltage, as well as full-scale conversion that utilizes a reference voltage derived from a 1.5V internal reference. The low-power technique applied to the MAX1115EKA+T IC enhances the ability of the device to digitize temperature information correctly and efficiently. The temperature sensor is calibrated such that it is accurate over a temperature range of -40°C to +125°C (+150°C over a smaller temperature range).

The MAX1115EKA+T device has a resolution of 1/16th and a current consumption of approximately 60uA. It is also easily integrated into application and measurement systems and supports both single-ended and differential inputs. Its low-power architecture is ideal for all battery driven applications and the entire package, including the temperature sensor and external components, requires minimal external components.

The most common applications for the MAX1115EKA+T IC include temperature and climatic monitoring systems, remote surveillance systems, industrial process measurement and control systems, automotive monitoring and HVAC systems, thermal cooling solutions and precision temperature measurement systems.

The working principle of the MAX1115EKA+T is based on the direct conversion of an analog signal, for instance, temperature, into a digital signal, as required by a digital system. An analog signal is first sent to the input of the device where it is rectified then, the amplified input is fed to a voltage-to-frequency converter, which generates a frequency proportional to the amplified signal. The generated frequency is then read by the digital switch inside the MAX1115EKA+T responsible for the conversion from the analog to the digital domain, resulting in the digital signal that is proportional to the temperature.

In short, the MAX1115EKA+T Analog to Digital Converter IC is an easy to use, low-power device ideal for digitizing temperature, pressure and other analog signals. It is DC coupled to the signal for true signal measurement over time and is an excellent choice for a range of applications, from thermistors and thermocouples to precision pressure gauges. The MAX1115EKA+T is engineered to provide accurate resolution, robust signal capture and conversion, and minimal power consumption.
