What is LTC1094CN#PBF?

The LTC1094CN#PBF is an analog-to-digital converter (ADC). It is a low power, 8-bit resolution, single-ended serial interface ADC that includes an internal track-and-hold circuit and a high speed CMOS comparator. The device supports both voltage and current input signals. It is capable of achieving high accuracy, low power dissipation, and low overall noise.

Application fields

The LTC1094CN#PBF is suitable for industrial automation and control, medical, and instrumentation applications where high accuracy and low power dissipation are needed. It is suitable for systems that require low power and space-saving solutions.

In industrial automation and control applications, the LTC1094CN#PBF can be used for sensing, measuring, and monitoring a variety of parameters such as temperature, pressure, humidity, etc. It can also be used to detect motion, position, and load. The device can be used in process control, energy management, and safety monitoring.

In medical applications, the ADC is suitable for vital signs monitoring in critical care. It can also be used for conventional medical equipment, such as ECG/EKG, patient monitoring, and medical imaging.

In instrumentation applications, such as digital control, signal conditioning, and data acquisition, the LTC1094CN#PBF can be used to measure electrical signals, such as voltage and current.

Working Principle

The device consists of three main blocks—an analog track-and-hold circuit, a successive-approximation register (SAR), and a high speed CMOS comparator. The analog track-and-hold circuit acquires the input signal and holds its value during the conversion process. The SAR determines the digital equivalent of the input signal by performing a binary search iteratively. The result is then provided as an 8-bit digital output.

The LTC1094CN#PBF operates in two-step mode, whereby the analog input signal is first tracked and then held before the analog-to-digital conversion takes place. This two-step process reduces the conversion time from the usual one-step process, improving performance and power efficiency.

The device can be controlled via a serial interface, which allows for programming parameters such as gain, reference voltage, and sample rate. The chip also provides several system-level features, such as temperature compensation, overload protection, and power-saving modes.
