Analog to Digital Converters (ADCs) are a key component of Data Acquisition systems. The MAX1306ECM+T is a dual ADC of the MAX1306 series of high-performance, low-power multi-channel LTCC-packaged data acquisition systems. This article discusses the application field of the MAX1306ECM+T in Data Acquisition systems, as well as the working principle of the device.

Application Field

The MAX1306ECM+T is part of the MAX1306 data acquisition family. The MAX1306 series is optimized for superior performance and low-power consumption, making it suitable for high-volume portable Data Acquisition systems. The MAX1306ECM+T is designed for use in a wide variety of applications, including medical, automotive, industrial, communications, and consumer applications. Its excellent signal-to-noise ratio, low power consumption, and small form factor make it ideal for use in space-sensitive Data Acquisition systems.

The MAX1306ECM+T is a high-precision 16-bit, 20kHz delta-sigma analog to digital converter. The device features an on-chip differential reference with an input range of 2.5V (±1.25V). It also features an internal jumperable clock, programmable gain settings, and an onboard power management system. The device has a low-noise voltage reference and is suitable for sampling rates up to 20 kHz. The wide 2.5V power supply range, low power consumption, and small leadless LTCC package make the device ideal for portable applications.

Working Principle

The MAX1306ECM+T utilizes a delta-sigma ADC architecture. In this architecture, analog input signals are converted to digital output signals via a delta-sigma modulator. The modulator is composed of a digital-to-analog converter (DAC), an analog summing node, a sample-and-hold stage, and an integrator that act together to convert the analog input signal to a digital output signal. The accuracy of the conversion is determined by the number of bits and noise rejection of the modulator, among other factors.

The MAX1306ECM+T features an on-chip 24-bit delta-sigma modulator coupled to a 2.5V power supply band-gap reference. The device includes a low-noise on-chip regulator, providing a low supply current to reduce overall power consumption. The modulator includes two on-chip internal switches to allow the user to select between single-ended and differential input signals.

The MAX1306ECM+T features an on-chip linear output buffer, which buffers the output of the modulator to the 16-bit parallel digital output. This buffer allows for high-accuracy, low-energy data read-outs with minimal power consumption. The device also features a programmable gain amplifier (PGA), which can be set for gains of 1, 2, 4, 8, and 16. The PGA allows for input levels up to ±10V.

The MAX1306ECM+T supports sampling rates up to 20KHz and integrates a variety of features, including a digital low-pass filter, programmable input range, and an onboard clock generator. In addition, the device has shutdown/active modes, making it suitable for applications that require frequent power cycling. The device is also available in a leadless 28-pin four-bump, small-outline, ceramic surface-mount package.

The MAX1306ECM+T is an ideal solution for high-performance, low-power Data Acquisition systems. Its wide range of features and excellent performance specifications make it an ideal choice for industrial and consumer applications. With its excellent signal-to-noise ratio and low power consumption, the MAX1306ECM+T is a high-performance, low-power ADC for Data Acquisition systems.
