Data Acquisition - Analog to Digital Converters (ADC) are now essential components in the modern electronics industry. ADC, commonly referred to as an A-to-D or A/D converter, will take an analog signal and convert it into a digital signal. The most commonly used ADC is the LTC2221CUP#PBF, a low-power, high-speed, complete analog-to-digital converter.

The technology behind the LTC2221CUP#PBF is CMOS-compatible and needs only a single 3.3V supply for normal operation. Additionally, it includes built-in low-dropout regulators, enabling a negative-power-supply operation.

This device can work with power-efficient analog input signals from thermocouples, strain gauges, or other process control or medical instruments. It is compatible with a broad range of differential and single-ended inputs, with both unipolar and variable input gains.

The LTC2221CUP#PBF features 16-bit resolution and noise-free performance. With its on-chip sample-and-hold circuitry, the device can process analog frequencies up to 30 kHz. In addition, it includes a “transmit ready” signal for a simple control over the analyte. Also, a digital noise filter has been developed, reducing the need of extra external filtering.

The key to its advanced performance are the two on-chip comparators, sample-and-hold elements, and a successive-approximation analog-to-digital converter. This system works by first measuring the input signal relative to a reference voltage. Then it samples the voltage signal and converts it into an 8-bit binary code. The output binary code is then recursively compared to the actual analog input. Finally, an 8-bit binary code is produced with a resolution of 4-bits accurate.

Aside from its samples and hold techniques, the device features advanced features such as an on-chip charge pump, a noise filter, and a power-down mode. The charge pump is used to generate a negative voltage from the 3.3V power supply, and the noise filter is used to reduce input noise. Also, the power-down mode enables the user to save a minimal amount of energy during long periods of inactivity.

As mentioned earlier, the LTC2221CUP#PBF offers a wide range of applications due to its low-power consumption and its compatibility with many devices. It can work with power-efficient analog input devices for data processing and medical instruments, and is capable of measuring differential and single-ended inputs, featuring both unipolar and variable input gains. Also, the on-chip comparators, sample-and-hold elements, and LDOs allow for a great power-saving performance.

The LTC2221CUP#PBF is a low-power, high-speed and intuitive analog-to-digital converter with many features and applications that have the ability to solve any data acquisition task. Its advanced features, such as its on-chip sample-and-hold circuitry, noise filter, and power-down mode, make it suitable for many data acquisition and control applications.
