MCP3428T-E/ST

The MCP3428T-E/ST is a general purpose 14-bit Analog-to-Digital Converter (ADC) for use in data acquisition systems. It is a multi-channel, low-noise, low-power device with a wide input voltage range and high accuracy that makes it ideal for a variety of applications.

The device integrates two channels of input and output with a voltage range of +/-10 volts. Its internal reference is 4.096 volt and the maximum input voltage is 20 volts. The MCP3428T-E/ST has an 14-bit resolution with a response time of 1·ms or <20·ms respectively. It also has an Automatic offset compensation, Gain error correction and Internal temperature sensor.

The MCP3428T-E/ST integrated circuits can be used in various signal conditioning applications such as thermocouple, RTD, acoustic, motion and other data acquisition instrumentation systems. It can also be used in controlling temperature and humidity environments in industrial and automation production systems. The device is available in a variety of packages, including a surface-mount package and a through-hole component package. It is also available in different speeds in order to suit specific applications.

The MCP3428T-E/ST is a delta-sigma ADC and uses a technique known as "sigma-delta modulation". In this technique, the signal to be digitized is filtered and fed into a digital filter. The output of this filter is then converted to a digital output using a number of successive approximations. Through this technique, the device is able to provide very accurate measurements, with an accuracy of up to 14 bits.

The device also provides a selectable gain setting that allows the user to adjust the signal resolution. This is done by increasing or decreasing the gain of the signal, thus providing a higher or lower resolution. This is especially useful in applications such as motion and acoustic that require different sensitivity. The gain settings are Cd, 0.5, 2, 4, 8, 16 and 32.

The MCP3428T-E/ST has an auto-zero feature which adjusts the input voltage to the reference level before the reading is taken. This ensures that any noise present in the signal is removed and the accuracy of the data can be better maintained. It also allows for efficient sampling of signals with very low input voltage, as it can measure the signal up to 0.05% of the full scale range without any drift.

The device also comes with a temperature sensor which can be used for temperature control applications. The internal temperature sensor allows for higher resolution measurements and accuracy, as it can measure temperature with an accuracy of up to 0.125 degrees Celsius. The temperature sensor can be used to trigger alarms or to activate cooling or heating systems when the pre-defined temperature range is exceeded.

The MCP3428T-E/ST is a very versatile and capable device that can be used in a wide variety of data acquisition and signal conditioning applications. It is simple to set up and use and provides accurate and reliable measurements. Thanks to its low-noise and low-power design, it is suitable for applications where battery power is limited, making it a great choice for low-power data acquisition systems.
