 X-Ray imaging is an old technology that today still progresses forward through the advancements in analog technology. Once the x-ray receivers receive the signals, the analog in the system amplifies, filters, and converts the signal to a digital format for the DSP. The accuracy and clarity of the x-ray system is directly related to the quality of the signal. Therefore, providing accurate analog solutions, such as references and regulators, is vital for a successful x-ray system. Component Highlights * A/D converter - select from several high-speed 8-, 10-, and 12-bit converters, many offering digital error correction and on-chip sample-and-hold circuits to minimize power consumption. * Voltage reference - with accuracy of 0.5% or better, these devices provide a precise reference of 1.024V-2.5V for the ADC. * Operational amplifier - devices with low noise and distortion combined with wide bandwidth enhance the performance of x-ray imaging systems. * Variable gain amplifier - wide-bandwidth VGAs include features such as shutdown and differential input and output, ideal for x-ray imaging applications. 1 Transimpedance Amplifier LMH6622MA LMH6622MAX LMH6622MM 2 Amp CLC5526MSA CLC5526MSAX LMH6502MA 3 LPF LM5068MMX-4 LM5068MMX-3 LM5068MMX-2 4 Reference LM4120 LM4125 LM4132 5 ADC ADC08060 ADC08100 ADC081000 6 Supervisory LM3702 LM3703 LM3704 7 Voltage Regulator LP3852 LP3855 LP38690 |
