Analog Devices AD526 Software Programmable Gain Amplifier Handbook
The AD526 is a single‑ended, monolithic software programmable gain amplifier offering binary gains of 1, 2, 4, 8 and 16, with a two‑chip cascade mode extending the range to 256. It integrates an amplifier, resistor network and TTL‑compatible latched inputs, requiring no external components and delivering low gain error and low non‑linearity for precision instrumentation.
This handbook provides a complete description of the device, including pin configuration, ordering options, performance specifications, theory of operation, transparent and latched modes, timing requirements, grounding and bypass techniques, cascaded operation, offset nulling methods, and examples of floating‑point A/D converter applications.
