The document describes a dual-channel, 12-bit, 80 MSPS ADC with analog input signal conditioning. It features a 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, 3.3 V compatible outputs, and 1.85 W per channel power. It is suitable for radar processing, phased array receivers, multichannel, multimode receivers, GPS antijamming receivers, and communications receivers.
The AD13280 is a dual‑channel, 12‑bit analog‑to‑digital converter that delivers up to 80 MSPS with integrated signal‑conditioning, selectable bipolar inputs and on‑chip amplifiers.
It operates from ±5 V analog supplies and a 3.3 V digital supply, provides 90 dB channel‑to‑channel isolation, and offers typical SNR of 70 dBFS at 10 MHz. The device is supplied in a 68‑lead ceramic leaded chip carrier.
