Analog Devices Inc. AD9083 Analog-to-Digital Converter
Analog Devices Inc. AD9083 Analog-to-Digital Converter is a 16-channel, 125MHz bandwidth, continuous-time Σ-Δ (CTSD) ADC. The AD9083 features an on-chip, programmable, single-pole antialiasing filter and termination resistor. It's designed for low power, small size, and ease of use. The 16 ADC cores features a first-order, CTSD modulator architecture with integrated, background nonlinearity correction logic and self-canceling dither. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.
