Precision measurement chips
This chip was designed to make precision measurements at a sample rate of up to 4kHz, for applications such as process control and medical instrumentation. The Crystal(R) CS553x uses the Crystal MultiPathTM amplifier core, an architecture that enables the devices to operate at a very low noise level6nV/=Hz at 0.1 Hz and very high resolution up to 23 bits. By integrating the multiplexer, amplifier, and analog-to-digital converter (ADC) on a single chip, the devices simplify analog front-end design for the system engineer.
