Analog-to-digital converters (ADC) are devices used to convert electrical signals from analog to digital form, enabling more precise data capture and data processing. The LTC2195CUKG is a 16-bit, low power, high input bandwidth analog-to-digital converter (ADC) with a very wide operating range of 2.7V to 7V. It is designed to provide high-accuracy and very low-noise conversion in the most challenging applications. This article will discuss the application fields and working principle of LTC2195CUKG.

Application Fields of LTC2195CUKG

The LTC2195CUKG is a low power, high input bandwidth ADC specifically designed for applications that require both precision and speed. Its wide operating range and integrated power control allow it to be used in a variety of data acquisition, signal processing, and digital control systems. Its low power consumption and small form factor make it ideal for low-power, portable, and/or embedded devices. Its integrated digital filter also eliminates the need for external filters, reducing system cost and complexity. Additionally, the LTC2195CUKG has a ±2.5 V minimum and ±10 V maximum input range, which makes it suitable for high-voltage industrial and medical applications. The LTC2195CUKG is ideal for a variety of applications, including:

• Data acquisition systems
• Signal conditioning and monitoring
• Medical systems and instrumentation
• Industrial systems and process control
• Automated test equipment (ATE)
• Analog frequency recovery
• Battery monitoring and power management

Working Principle of LTC2195CUKG

The LTC2195CUKG analog-to-digital converter employs a successive approximation register (SAR) architecture to provide high-speed, single-cycle conversions with a resolution of 16 bits and an integrated digital filter that eliminates the need for external passive components. It also has two input channels and different on-chip filters so it can be used to measure both fast and low frequency signals simultaneously. Additionally, its auto ranging and input buffer ensures that the signal is correctly processed before conversion. Its small form factor and low power consumption make it an ideal choice for low-power or embedded applications.

The basic operation of the LTC2195CUKG is as follows. An analog input is received by the ADC’s input buffer and then adjusted for the input range. The signal is then converted to binary rather than a voltage measurement and is sent to the successive approximation register. The SAR then compares the signal to a reference signal and sets each bit of the output accordingly. The converted data is then sent to the output stage and converted to a digital format. The result is a 16-bit digital representation of the analog input.

The LTC2195CUKG provides a highly accurate and low-noise data acquisition solution with its integrated power-on reset, rail-to-rail input buffers, high resolution, and wide operating range. Its small form factor and low-power make it well-suited for a variety of data acquisition and signal processing applications in medical, industrial, ATE, and power management systems.
