The AD13280 is a dual-channel, 12-bit, 80 MSPS ADC with analog input signal conditioning. Its features include: guaranteed sample rate of 80 MSPS, ±1% gain error for channel-to-channel matching, 90 dB channel-to-channel isolation, DC-coupled signal conditioning, 80 dB spurious-free dynamic range, selectable bipolar inputs (±1 V and ±0.5 V ranges), integral single-pole, low-pass Nyquist filter, twos complement output format, 3.3V compatible outputs, and 1.85W per channel power consumption.
The AD13280 is a dual‑channel, 12‑bit analog‑to‑digital converter that integrates amplifiers, references, ADC cores and output termination. It operates from a +5 V analog supply and a 3.3 V digital supply, delivering up to 80 MSPS conversion rate with 90 dB channel‑to‑channel isolation.
The device offers selectable single‑ended or differential inputs, multiple input voltage ranges, and includes on‑chip track‑and‑hold circuitry. It is supplied in a 68‑lead ceramic gull‑wing package and is targeted at radar, phased‑array, GPS, and communications receivers.
