概述

Description

AD7228ABRZ is an Analog Devices multi-channel analog-to-digital converter. It provides eight analog inputs through an internal multiplexer and converts them with a successive-approximation ADC, delivering data to a host via a serial (SPI‑like) interface. Designed for data acquisition and instrumentation, it enables multiplexed reading of multiple sensors or signals with a compact, low-power device. Key features often include programmable sampling rates, optional internal reference, and a microcontroller-friendly serial interface. The ABRZ suffix indicates a RoHS-compliant (lead-free) package variant. For exact specs (bit depth, sampling rate, references, power, and package details), consult the AD7228ABRZ datasheet.

Features

AD7228ABRZ features (typical):
- 8-channel analog input with a multiplexed front end
- Serial data interface (SPI-compatible)
- Differential or single-ended input options
- Programmable gain/reference (internal reference option)
- High-precision ADC with wide dynamic range and low noise
- Low power operation with multiple power-down modes
- Industrial temperature range
- 28-pin RoHS-compliant package (lead-free) with Tape & Reel (ABRZ) packaging
Note: for exact specifications (bits, sample rate, INL/DNL, voltage ranges), refer to the latest datasheet.

Package

Pb-free, RoHS-compliant 28-pin TSSOP package.

Pinout

- Pin count: 28 pins
- Function: AD7228ABRZ is an 8-channel multiplexed analog-to-digital converter (SAR ADC) with a serial (SPI-compatible) interface. It provides multiplexed inputs and converts them to digital data for host microprocessors.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
What kind of company: An American multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and digital signal processing integrated circuits for various industries (industrial, automotive, communications, healthcare, consumer).

Application

AD7228ABRZ is suited for multi-channel data acquisition and sensor interfacing. Typical applications include industrial automation and process control, instrumentation and test equipment, automotive sensing and diagnostics, medical instrumentation, and portable/battery-powered measurement devices.

Equivalent

There isn’t an exact one‑to‑one equivalent for AD7228ABRZ. Substitutions depend on specs. Please share: resolution, channels, max sample rate, interface (SPI/I2C), input ranges, power rails, and package. With those, I can suggest closest cross‑reference parts. Otherwise, use ADI’s Cross Reference tool or distributor databases (Digi‑Key/Mouser) to find parts with matching specs.
