The application field and working principle of the Linear Technology Corporation’s LTC2185IUP is a specialized type of analog to digital converter (ADC). This converter was designed for diverse application fields where data acquisition is an issue. It is equipped to handle robust signals that have large frequency components, encompassing up to 248MHz (-3dB) of bandwidth, a spurious-free dynamic range (SFDR) of 70dB and 65dBc as well as very low noise. The working principle of this converter is also quite simple and straightforward.

The LTC2185IUP comes with an input-referred voltage noise density specification of 15nV/√Hz and a maximum sampling frequency of 1500MHz. This allows it to handle multiple analog signals with varying frequencies and resolutions. It can also be used in applications with the highest dynamic range and speed requirements such as high-resolution imaging and high-dynamic-range scanning. Its low-noise capability coupled with its high-resolution ADCs makes it ideal for applications related to high-end motion control, such as feedback control of electric motors and servos.

The converter works by first converting analog signals into digital data, which is then stored in its integrated Digital Signal Processor (DSP). This allows for the use of the DSP’s advanced signal-processing capability for more efficient data acquisition. The converter is also able to accept multiple channels of data, making it suitable for multi-channel input systems. Additionally, the use of sigma-delta architecture provides superior dynamic performance, excellent signal-to-noise ratio (SNR) and a wide dynamic range.

The converter offers two choices of input signal range which is the unipolar 0V to 10V and the bipolar ±5V range. It has a differential input stage with a maximum DC input voltage of up to ±2.5V. The output is generated in the form of a single ended voltage-mode signal, with a resolution of 8-bits. It also includes an on-chip clock synthesizer with an internal 6-bit programmable clock multiplier for setting the sampling rate.

The LTC2185IUP can operate from a single supply voltage from 1.8V to 5.5V allowing it to be employed in a wide range of battery-powered and system applications. It is available in an 8-Pin TSOT-23 and a 10-Pin MSOP package, offering an extremely compact and signal to power design. Thanks to its on-chip ESD protection, it is well protected against electro-static discharges, thus providing improved reliability.

Overall, the LTC2185IUP is an excellent choice for analog to digital conversion, providing high-performance, low-power operation and a wide dynamic range. It is ideal for various applications in data acquisition, imaging and motion control, where accurate and efficient signal processing is desired. With its superior performance and user-friendly design, it is an ideal solution for many applications.
