Data Acquisition - Analog to Digital Converters (ADC)

The LTC2280IUP#TRPBF is an ultra-low power 16-bit delta-sigma ADC that offers high accuracy and low power dissipation in a compact package. The device offers a state-of-the-art maximum single-channel input dynamic range of up to ±7V for the single-ended input configuration. The device features 16-bit delta-sigma (Δ-σ) analogue to digital conversion. The LTC2280IUP#TRPBF supports a maximum sampling rate of 210 kS/s and uses a wide range of programmemable gain elements for up to a total signal gain of 51 dB.The device is a low power device with a power dissipation of only 200 μA at a 3V supply voltage. This makes it an excellent choice for portable and battery-powered applications. The LTC2280IUP#TRPBF also has a low voltage range of up to 2.25V and a wide temperature range of up to -40°C to +105°C. It is suitable for medical, industrial and automotive applications.The LTC2280IUP#TRPBF uses a 5bit parallel interface, compatible with industry-standard SPI and I2C buses, to interface with the rest of the circuit. The device is factory programmed with 16-bit resolution. The device supports both 8-bit and 16-bit modes, allowing it to be used with a wide range of system bus widths. The device also supports a wide range of sample rates, from 6.25 kS/s to 210 kS/s, giving it a very low latency response.The working principle of the LTC2280IUP#TRPBF is a delta-sigma (Δ-σ) analogue-to-digital conversion. The analog input signal is converted to a digital signal in four stages. In the first stage, the signal is attenuated by the programmable gain stage. This gain stage allows the device to achieve its wide range of input dynamic range. Then, the signal is sent to the second stage for low-pass filtering, which removes unwanted high-frequency components. The signal is then passed through an integrator, which performs the analog-to-digital conversion of the signal. Finally, the output of the integrator is fed to a digital filter, which reduces the noise and jitter of the signal.The LTC2280IUP#TRPBF can be used in many applications, such as medical diagnostics, industrial automation, scientific instrumentation, process control, and data acquisition systems. It is suitable for precision data acquisition applications, such as physiological laboratory tests, data logging, medical sensors, and temperature measurement. The device can be used for audio systems, environmental monitoring and remote sensing applications. The device is also suitable for Digital Signal Processing (DSP) applications for voice and audio signal analysis.In conclusion, the LTC2280IUP#TRPBF is an ultra-low power 16-bit delta-sigma ADC that offers a low power consumption and wide range of signal conditioning. It is suitable for a variety of precision data acquisition and DSP applications, as well as for medical, industrial and automotive applications. The device uses a 5bit parallel interface, compatible with industry-standard SPI and I2C buses, to interface with the rest of the circuit. The device is factory programmed with 16-bit resolution and supports both 8-bit and 16-bit modes, allowing it to be used with a wide range of system bus widths. The device also supports a wide range of sample rates, from 6.25 kS/s to 210 kS/s, giving it a very low latency response.
