Introduction
HCT6961-x is a SPI-interface 16/8-channel, 24-bit high-precision ADC IC, integrating a 1×–128× programmable low-noise instrumentation amplifier, high-precision Sigma-Delta ADC, dual precision current sources, high-performance temperature sensor, 5ppm/℃ high-precision voltage reference, bias voltage output circuit, and precision internal RC clock source. The ADC achieves an effective resolution of 23.3 bits @ 1× PGA and 21.8 bits @ 64× PGA, with equivalent input noise as low as 8nV/√Hz, offset voltage of 1μV, and offset temperature coefficient below 10nV/℃. The output data rate is configurable from 3.125Hz to 6400Hz, or 6.25Hz to 12800Hz in high-power and frequency-doubling modes. Suitable for high-performance temperature sensors, analytical balances, industrial process control, DC/AC power measurement, instrumentation, and other applications requiring high-precision and low-offset measurements.
