The PCM1803DBR is a high resolution ADC and DAC converter designed for use in fields that require precision and advanced signal-processing technology. It is a two-channel device that provides both analog and digital outputs with a 16-bit resolution. It has an operating temperature range of -40°C to +85°C, which enables it to work in severe environments. The device is also capable of sampling up to 300kHz, which makes it suitable for high speed applications.

The PCM1803DBR utilizes three additional technologies to ensure the accuracy of its measurements. These technologies include a patented powerline transient protection circuit, a close-spaced 8-bit digital-to-analog converter (DAC) and a built-in voltage reference. The transient protection circuit helps to reject interference from in-line power sources such as alternating current (AC) power lines and well-regulated dc power supplies. The 8-bit DAC helps to produce an accurate analog output signal by adjusting the voltage level for each output channel. The built-in voltage reference keeps the precision level of each channel within ±6mV, making it an ideal solution for precision measurements.

The PCM1803DBR works on the principle of sigma-delta conversion. This approach involves converting an analog signal into a digital signal by sampling it at discrete intervals. The analog input signal is then compared to a reference signal and the difference between the two signals is quantified. This quantified difference is then converted to a series of pulses that can be used to produce both an analog and digital output.

In data acquisition applications, the PCM1803DBR can be used to measure various parameters such as temperature, pressure, force, acceleration and voltage. It can be used to accurately detect changes in the physical environment and respond accordingly. The device also features an on-chip temperature sensor to monitor the ambient temperature of the environment, allowing the device to periodically adjust its performance.

The PCM1803DBR is an ideal solution for applications that require precision and advanced signal processing technology. Its high resolution and advanced protection circuits make it suitable for use in harsh environments as well. The device’s sigma-delta conversion technique ensures accurate measurements, making it an excellent choice for data acquisition applications in many fields.
