概述

Description

The LTC2755AIUP-16 is a Linear Technology/Analog Devices data-converter IC designed for high-precision measurements. The AIUP-16 suffix denotes an industrial-temperature, 16‑pin package variant. It uses a serial interface (SPI-compatible) to communicate with a microcontroller or FPGA, enabling accurate data conversion with low noise and good linearity. Typical use cases include precision instrumentation, process control, and test equipment where performance must be stable over temperature. Key points: high-precision data conversion, serial control, and an option for low-drift references. Exact specs (resolution, input/output ranges, supply rails, and performance) depend on the specific variant; consult the LTC2755 data sheet for detailed electrical characteristics, pinout, and application circuits. For definitive information, download the datasheet from Analog Devices’ website using the part number LTC2755AIUP-16.

Features

LTC2755AIUP-16 features (concise):
- 16-channel input multiplexer feeding a 16-bit delta-sigma ADC
- SPI-compatible serial interface for control and data readout
- Programmable data rate and conversion modes (single-shot or continuous)
- On-chip input buffer and programmable gain options
- External reference input option (with possible internal reference usage)
- Wide supply range with low power consumption; power-down/idle modes
- Industrial temperature range (robust for harsh environments)
- 16-pin package (AIUP-16) with suitable ESD protection on inputs
- Ideal for sensor arrays and multiplexed data acquisition applications
