Interface - Drivers, Receivers, Transceivers: LTC1387CG#PBF

The LTC1387CG#PBF (LTC1387) is a type of general purpose, low power, single-chip Analog-to-Digital Converter (ADC) developed by Linear Technology. It is primarily used for applications in the medical, automotive, and industrial sector.

The LTC1387CG#PBF is used for the conversion of analog signals (including both single-ended and differential input-signals) into digital signals via its programmable, successive approximation register (SAR) ADC. It features a wide supply voltage (2.7V to 5.5V) and can operate over the temperature range of -40℃ to +85℃. It also has a high precision 16-bit resolution and can provide a quiescent current as low as 0.8mW in standby mode.

The LTC1387CG#PBF also has a large number of programmable features, such as internal reference voltage, analog input range, digital input monitor and a host of other optional features, which can be tailored to application-specific needs.

In addition, it offers a very high throughput rate of up to 1.2Msps and can accommodate variable power supplies. It has a flexible, wideband architecture to reduce system noise and reduce the time required for data conversion. Finally, the LTC1387CG#PBF also features several output formats, including: binary, 2’s compliment, twos complement with/without sign magnification, offset binary and gray code.

The working principle of the LTC1387CG#PBF is based on the concept of successive approximation ADC. The ADC utilizes a SAR (successive approximation register) to sample and convert the analog input signal into its digital representation. During the process of converting an analog input signal, the SAR produces a series of digital words, which are then fed to a separate digital logic unit (DU) to determine the final digital output code. The DU applies the necessary algorithm, based on the input signal, to determine the digital output code, which is then read out by the user.

The process of successive approximation ADC works by successively approximating the analog signal value by the increments. The SAR then performs a successive approximation register process and adjusts itself to the input voltage. As it is integrated in the ADC, it then produces the digital equivalent of the analog input signal. This technique allows for a high sampling rate and low power consumption, making it an ideal choice for applications in medical and automotive sectors.

To sum up, the LTC1387CG#PBF is a very flexible and reliable single-chip ADC, which is used for the conversion of analog signals into digital signals, mainly for applications in the medical, automotive and industrial sectors. It features a very low quiescent current, wide supply voltage, high precision and a wideband architecture. In addition, its flexible, successive approximation, register ADC allows for fast and accurate data conversion.
