Introduction
HCT6511 is a dual-channel, 24-bit high-precision ADC with an SPI interface. It integrates a programmable low-noise amplifier with selectable gains of 1, 32, 64, or 128, a high-precision Sigma-Delta ADC, a voltage reference, and a high-frequency internal RC clock source. At 128× PGA configuration, the ADC achieves an effective resolution of 19.8 bits, with an equivalent input noise as low as 16nV/√Hz and a zero-point drift of 5μV.
