LTC2268IUJ-14

Data Acquisition - Analog to Digital Converters (ADC) is the widely used component in electronic systems. The LTC2268IUJ-14 is one of the family of ADCs specifically used for high speed, high resolution, low power applications. The LTC2268IUJ-14 provides excellent performance both in terms of sampling rate and conversion resolution.

Application field of LTC2268IUJ-14:

The LTC2268IUJ-14 is ideal for a wide range of applications including data acquisition systems, power converters and digital audio. It can be used in medical imaging systems to digitize the analog signals from ECG and EEG measurements. It is also used in industrial systems such as high speed data converters in engine controllers and automation systems. Furthermore, the LTC2268IUJ-14 can be used in consumer applications such as consumer cameras, HDTV and Digital Video Recorders (DVR).

Working Principle of LTC2268IUJ-14:

The LTC2268IUJ-14 is a high speed, 14-bit, SAR-based ADC with an internal clock. The ADC consists of a sampling-and-hold section, serial-input shift register and a flash converter. The sampling-and-hold section captures the analog input voltage. The serial-input shift register stores the sampled voltage and then clocks it into a flash converter. The flash converter then performs an analog-to-digital conversion. The flash converter is also responsible for encoding the analog input voltage into a 14-bit digital code.

The ADC also has a parallel output latch. Once the conversion is completed, the parallel register stores the digital output code. The output remains valid until a new conversion has started. The LTC2268IUJ-14 has a pipeline architecture with no missing codes, which ensures that all input level analog signals can be accurately converted.

The ADC is designed with a low jitter clock. This allows it to accurately sample the analog input signal with a sampling frequency of up to 250MSPS. The LTC2268IUJ-14 can operate on single +5V supply and consumes minimal power. The ADC also has an internal temperature sensor which allows the chip to monitor and compensate for temperature variations.

In summary, the LTC2268IUJ-14 is an ideal choice for high speed, high resolution, low power applications with a wide range of applications, including data acquisition systems, power converters and digital audio. Its low jitter clock and internal temperature sensor make it an ideal choice for precision and accurate applications.
