Analog Devices AD7579/AD7580 Datasheet
The AD7579 and AD7580 are 10‑bit successive‑approximation ADCs that operate from a single +5 V supply. They offer differential analog inputs that accept unipolar or bipolar signals and provide selectable input ranges of 0‑2.5 V, 0‑5 V, or ±2.5 V. The devices feature an on‑chip sample‑and‑hold, low power dissipation (≤50 mW), and a choice of data formats (8+2 bits for AD7579, 10‑bit parallel for AD7580).
Key specifications include a conversion time of about 16.9‑18.5 µs, a maximum sampling rate of 50 kHz (25 kHz input bandwidth), SNR up to 85 dB, and various dynamic performance figures such as THD and IMD. The datasheet also provides timing diagrams, absolute maximum ratings, pin configurations, and ordering information for multiple package options.
