The document describes the features and characteristics of a 12-bit, 4-channel serial output sampling analog-to-digital converter.
The ADS7841 from Texas Instruments is a 4‑channel, 12‑bit sampling ADC with a synchronous serial interface. It operates from a single supply of 2.7 V to 5 V and offers both single‑ended and differential input configurations. Typical power dissipation is 2 mW at 200 kHz throughput, and a shutdown mode reduces consumption to under 15 µW.
The device is offered in DIP‑16 or SSOP‑16 packages and is specified for temperatures from –40 °C to +125 °C. Detailed electrical characteristics, pin configurations, and ordering information are provided in the datasheet.
