Analog Devices AD7711A Signal Conditioning ADC Datasheet
The AD7711A is a complete analog front‑end for low‑frequency measurement applications. It provides a 24‑bit sigma‑delta conversion with programmable gain (1‑128), differential inputs, and an on‑chip 400 µA RTD excitation current. The device can operate from a single 5‑10 V supply or dual supplies and includes a low‑power mode (7 mW typical).
The datasheet details electrical specifications, pin configurations, timing characteristics, and calibration options. It also lists absolute maximum ratings, recommended operating conditions, and ESD sensitivity warnings for designers integrating the part into microcontroller‑based systems.

Questions answered in these manuals
What is the input voltage range for normal operation?
The input voltage range depends on the selected gain; for unipolar mode it is 0 to +VGG‑1 V, and for bipolar mode it is ±VGG‑1 V.
