Visão Geral
Description
The ADS7835E/2K5 is Analog Devices’ low‑power, 8‑channel, 12‑bit successive‑approximation ADC with a built‑in input multiplexer and a serial SPI‑like interface. It multiplexes eight analog inputs into a single SAR converter, enabling sequential channel scans controlled by a microcontroller. It runs from a single supply (roughly 2.7–5.25 V) and uses an external reference (0–Vref range) if desired. Features include an integrated sample/hold, a programmable conversion start, and a four‑wire-like serial data path (DIN/DOUT + clock/control lines) for reading results. The E/2K5 suffix indicates a specific package/temperature variant. Applications include battery-powered instrumentation, sensor front‑ends, automotive and industrial control. Benefits: high channel density, compact package, simple serial interface, and low power. For exact timing, timing diagrams, and electrical characteristics, refer to the ADS7835E/2K5 datasheet.
Pinout
- Pin count: 16 pins (SOIC-16 / TSSOP-16).
- Function: 8-channel, 12‑bit successive‑approximation ADC with an input multiplexer. AIN0–AIN7 are multiplexed to the ADC; external reference (VREF+, 2.5V variant “/2K5”). Digital interface is SPI‑like with DIN, DOUT, SCLK, CS, plus CNVST/CONVST to start conversion. Pins include VDD, AGND, DGND, and VREF.
