概述
Description
AD7853ARZ is a 12‑bit, eight‑channel multiplexed ADC from Analog Devices. It uses a successive‑approximation (SAR) architecture with an on‑chip sample‑and‑hold and a multiplexer to digitize up to eight analog inputs. The conversion results are output over a serial interface that is SPI‑like, facilitating easy microcontroller or DSP interfacing. The ARZ suffix denotes a RoHS‑compliant surface‑mount package.
Key points:
- 12‑bit resolution with multiplexed inputs
- SAR ADC with serial (SPI‑style) data interface
- On‑chip sample-and-hold
- Suitable for data acquisition, instrumentation, and control systems requiring compact, multi‑channel digitization
For exact electrical specs (speed, input range, reference requirements, power, timing), consult the AD7853ARZ datasheet.
