MAX145BEUA+ is a data acquisition device, classified as Analog to Digital Converters (ADC). This article examines the range of applications and also the working principle of the MAX145BEUA+.
The MAX145BEUA+ is a 12-bit, voltage output, analog-to-digital converter (ADC). It is a low-power, single-ended, monolithic device that is ideal for applications within instrumentation, control and test systems. The power supply requirements are between 4.75 V and 5.25 V, and the maximum integration of the device is enabled by 200 kHz conversion rates with a maximum throughput rate of 500K sample/s.
The applications for the MAX145BEUA+ are extremely varied. The device is suitable for use in sample-and-hold circuits, A/D and D/A conversion systems, analog signal processing systems, temperature measuring and control systems, and general-purpose data acquisition systems. The device is also used in a range of industrial, scientific and professional applications.
The working principle of the MAX145BEUA+ is based on a differential voltage reference circuit, which uses a pair of capacitors connected to a voltage reference. The voltage reference is divided into two parts (reference inputs and output) and the differential voltage input is connected to the reference output to signal the arrangement of the most-significant bit. This is then followed by a series of comparator circuits, each applied to one of the remaining reference inputs, finally ending with the least-significant bit.
The comparator circuits operate in the same way and consist of a pair of transistors connected in a differential amplifier circuit. The reference voltage is compared to the reference voltage generated by the reference circuit, and the output is determined by the difference between the two voltage levels. The output from the comparator circuit can then be used to indicate the value of the data being converted.
The MAX145BEUA+ also features a two complement output that is enabled by the control circuit. This inverse output allows the device to directly perform two-way operations such as addition and subtraction, which is beneficial for applications that involve complex operations.
In conclusion, the MAX145BEUA+ is a low-power, analog-to-digital converter (ADC) with an extensive range of applications. It is suitable for use in a variety of instrumentation, control and test systems, with the added benefit of two complement output enabling complex operations. The device is powered by a single voltage supply and is suitable for operation in temperatures up to 85°C.
