The LTC1092CN8, designed by Linear Technology — an industry leader in analogue integrated circuits — is a dual, low-noise, 12-bit, precision A/D converter with improved temperature stability. Besides, the noise generated by this device is lower than most commercial A/D converters. This article will focus on the application field and working principle of the LTC1092CN8.
Application Field
The LTC1092CN8 is used in applications that require accurate analogue-to-digital conversion. It is ideal for measuring temperatures, pressures, motions, vibrations, and a variety of other physical parameters with very high precision. It is especially suited for applications requiring low-noise and superior temperature drift performance.
Additionally, the LTC1092CN8 can be employed in a variety of medical, industrial, and consumer applications. In medical applications, it can be used to measure body temperature, pressure, and ECG data. In industrial applications, it can be used to measure motion, force, and pressure in actuators. In consumer applications, it can be used to measure battery levels, audio signals, and automotive engine sounds.
The LTC1092CN8 provides superior accuracy and low noise performance. It has a wide input range of 0 to 5V (maximum) and an output range of 0 to 12 bits. Additionally, the included internal clock produces digitized data with a maximum sampling rate of 10 kHz. Furthermore, it contains error correction code (ECC) and a power-down mode which allows for low-power operation.
Working Principle
The LTC1092CN8 works on the principles of successive approximation. During the operation, the internal analog-to-digital converter (ADC) progressively refines an analogue signal, based on its digital representation, until the desired 90-degree phase accuracy is achieved. The process begins by comparing a high-speed initial approximation with a known reference. If the two signals are not equal, the ADC applies features such as psychometric shaping, propagation delay adjustment, and voltage linearity adjustment to provide accurate and consistent signals.
The ADC contains a 16-bit spanned flash A/D converter, an 8-bit circuit, and a wide-band noise cancellation circuit. The wide-band noise cancellation circuit reduces harmonic distortion caused by outside noise. Furthermore, the integrated comparator circuit provides a precise logic windows for monitoring the analogue signal.
The LTC1092CN8 also provides a multiplexable voltage reference circuit with a superb temperature stability and well-balanced performance. This feature makes the device suitable for designing accurate, stable systems. Additionally, the device contains Frame Averaging which enables a fast converter signal cleaning. The converter produces its most accurate result when multiple conversions are averaged. This feature is helpful in applications where noise and unwanted signals may cause inaccurate results.
To ensure superior performance, the LTC1092CN8 is manufactured in a low noise 8-pin micro-tip socket. The socket is designed to provide an efficient thermal and electrical connection between the internal and external circuits. The onboard burning circuit ensures accurate performance. The converter’s features and superior thermal characteristics make it suitable for high-precision measurement applications.
Conclusion
The LTC1092CN8 is a low-noise, 12-bit, precision A/D converter with improved temperature stability. It is designed to provide accurate analogue-to-digital conversion. The device works on the principles of successive approximation and contains a 16-bit spanned flash ADC, an 8-bit circuit, and a wide-band noise cancellation circuit. It also contains a multiplexable voltage reference circuit with superior temperature stability and well-balanced performance. These features make the LTC1092CN8 suitable for applications that require low-noise, precise measurement and excellent temperature drift performance.
