概要
Description
LTC2755AIUP-16 is a Linear Technology (now Analog Devices) data-converter device. The “2755” identifies the model, and “AIUP-16” encodes packaging and operating range: Industrial-temperature variant in a 16‑lead package. It uses a serial (SPI-compatible) interface to communicate with a host processor, making it suitable for precision instrumentation and control applications such as data acquisition and sensor interfacing. The LTC2755 family is designed for high-accuracy, low-noise operation with robust performance over temperature.
Key takeaway: it’s a 16‑bit precision data converter in a 16‑lead package with an SPI-style interface. For exact specs—resolution, sampling rate, input configuration, reference requirements, power rails, and pinout—consult the LTC2755 datasheet on Analog Devices’ website. If you share your application details (speed, input type, reference, supply), I can point to the specific figures and recommendations.
