Analog Devices AD7798/AD7799 Datasheet
The AD7798 and AD7799 are precision analog‑to‑digital converters offering 16‑ or 24‑bit resolution, low RMS noise, and programmable gain. They include an on‑chip instrumentation amplifier, low‑side power switch, reference detect, and programmable digital outputs, all housed in a 16‑lead TSSOP package.
These devices target applications such as weigh scales, pressure measurement, strain‑gauge transducers, gas analysis, industrial process control, portable instrumentation, and blood analysis. They operate from a 2.7 V to 5.25 V supply over a temperature range of –40 °C to +105 °C.
