Working Principle of the HI5767/6CA ADC

The HI5767/6CA ADC has a two-step conversion process which begins with a differential-sensing amplifier. This amplifier amplifies the analog signal to generate a high-resolution digital output. The differential amplifier ensures a wide dynamic range, which allows for accurate conversion of low-level signals.

The second step in the HI5767/6CA ADC’s conversion process uses a parallel-array of switched capacitors. These capacitors are connected in such a way that the analog input voltage is converted into a proportional digital output. The capacitors can be switched on and off to control the transfer of charge, allowing the ADC to determine the level of the analog voltage.

The HI5767/6CA ADC also incorporates a low-noise auto-zero amplifier. This amplifier helps to reduce the offset errors that can arise with traditional ADC circuitry. In addition, the ADC contains an onboard analog-to-digital compensator which helps to reduce errors due to small differences in the transfer characteristics of individual converter elements.

Conclusion

The HI5767/6CA ADC is a high-resolution 16-bit analog-to-digital converter suitable for a wide range of applications. It utilizes a two-step conversion process and utilizes differential sensing, a parallel-array of switched capacitors, a low-noise auto-zero amplifier and an onboard analog compensator for increased accuracy. For these reasons, the HI5767/6CA is an excellent choice for a variety of applications, from biomedical to communications.
