The ADC12D1620 device is a versatile analog-to-digital converter (ADC) with an innovative architecture, which permits very high-speed operation. The controls available ease the application of the device to circuit solutions. Optimum performance requires adherence to the provisions discussed here and in the Application Information. This section covers an overview, a description of control modes (extended control mode and non-extended control mode), and features.

The ADC12D1620 device uses a calibrated folding and interpolating architecture that achieves a high effective number of bits (ENOB). The use of folding amplifiers greatly reduces the number of comparators and power consumption. Interpolation reduces the number of front-end amplifiers required, minimizing the load on the input signal and further reducing power requirements. In addition to correcting other non-idealities, on-chip calibration reduces the INL bow often seen with folding architectures. The result is an extremely fast, high-performance, low-power converter.
