AD5590 is a 16 Input, 16 Output Analog I/O Port with Integrated Amplifiers produced by Analog Devices. It features 12-bit successive approximation ADC, 16 inputs, 16 outputs, fast throughput rate, wide input bandwidth, etc. It is suitable for optical line cards, base stations, general-purpose analog I/O, monitoring and control, etc.
The AD5590 is a 16‑channel input and 16‑channel output analog I/O port that includes eight low‑noise, single‑supply amplifiers and on‑chip 12‑bit ADC and DAC converters. It operates from a single 4.5 V to 5.25 V supply and supports a 1 MSPS throughput rate with flexible serial interfaces such as SPI, QSPI, Microwire, and DSP‑compatible modes.
The document provides functional block diagrams, detailed specifications for the ADC, DAC, and operational amplifiers, timing characteristics, absolute maximum ratings, pin configurations, and typical performance curves. It also includes revision history, ordering information, and application notes for uses such as optical line cards, base stations, and general‑purpose analog I/O.
