Data Acquisition - Analog to Digital Converters (ADC)Analog to digital converters (ADCs) play a critical role in modern devices, translating the myriad of analog signals from the natural world into digital streams to be understood by computers. As a result, data acquisition and conversion technology are always a major focus of modern electronic engineering. The LTC2282CUP is a versatile, low power, dual, 12-bit analog-to-digital converter (ADC), featuring higher precision, lower jitter and faster speed than most other devices on the market. The LTC2282CUP is an integrated device, featuring two separate, independent, low-noise, wideband, 12-bit sigma-delta ADCs. Each ADC supports 18-bit resolution when using the internal 256x over-sampling rate. The LTC2282CUP’s reference voltage can be adjusted internally, providing the ability to output either a low voltage or a high voltage reference. When operating at the maximum frequency of conversion rate of 250 kHz, the LTC2282CUP has a wide dynamic range and low input distortion, making it well-suited for a variety of applications.The LTC2282CUP is ideal for use in a wide range of applications, including streaming sensor data, automotive and industrial applications, medical systems, and smart homes. In addition, the LTC2282CUP is an excellent choice for applications that require high performance operation but that don\'t need the full power of more expensive devices.The ADCs on the LTC2282CUP incorporate the popular sigma-delta architecture, which converts an analog input signal into a digital output. This process begins with a low-noise amplifier, which provides a gain on the input signal before it is sent to the low-level converter. As the low-level converter samples the signal, it is filtered and compared against a reference voltage. This comparison results in digital codes that represent the analog input values. The performance characteristics of the LTC2282CUP are determined primarily by the input signal characteristics and the reference voltage. The maximum conversion rate is determined by the input signals’ frequency and the sample-and-hold time of the decimator, while the maximum sampling rate is determined by the reference voltage. Additionally, the LTC2282CUP features an on-chip low-noise PLL to help reduce clock jitter and provide high-frequency, low-noise performance.The LTC2282CUP includes an on-chip temperature sensor, which is used to adjust the temperature of the device in order to compensate for errors caused by the temperature of the reference. Additionally, the integrated voltage reference can be adjusted to compensate for the effects of environmental and system voltage changes. Additionally, if desired, the on-chip regulator can be enabled to supply a stable, regulated output voltage of up to 6 volts.In conclusion, the LTC2282CUP is a low-power, dual, 12-bit integrated analog-to-digital converter. The ADC features an over-sampling conversion rate of up to 250 kHz and 18-bit resolution, making it an excellent choice for high-performance applications. Additionally, the device includes a temperature sensor and integrated voltage reference, making it suitable for low-noise and precise applications.
