Overview

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.

Features

Key features of the AD7853ARZ (as per its datasheet):
- 12-bit resolution
- 8-channel multiplexed analog input
- SPI-compatible serial interface (SCLK, CS, DIN, DOUT)
- On-chip track-and-hold amplifier
- External reference input (with optional internal reference)
- Single-supply operation (typical 5V)
- Suitable for low-power, small-footprint applications
- (Package code ARZ specifies the specific package variant)

Pinout

- Pin count: 28 pins (28‑lead package, ARZ suffix denotes the 28‑lead plastic package).
- Function: 12‑bit successive‑approximation analog‑to‑digital converter with a serial (SPI/MICROWIRE‑like) interface (and built‑in sample/hold for data acquisition).

Manufacturer
