Description

AD7225LPZ is an Analog Devices device in the AD722x family, designed as a precision analog-to-digital converter (ADC) for data acquisition. It comes in a lead-free LPZ package and provides a serial interface (SPI-like) to connect with microcontrollers, making it suitable for compact, low-power instrumentation and embedded control applications. It’s used to digitize sensor signals for automotive, industrial, and scientific systems. For exact specifications—resolution, sample rate, input range, supply voltages, and pinout—check the AD7225 datasheet and product page, since LPZ denotes a specific package option.

Features

AD7225LPZ features (concise):
- 8-channel, 12-bit ADC with multiplexed analog inputs
- SPI-compatible serial interface for control and data transfer
- On-chip sample-and-hold with track-and-hold capability
- Programmable channel scan sequence and dwell times
- Internal reference option (and external reference support)
- Wide supply range (typical 2.7V–5.25V)
- Low-power operation with standby/power-down modes
- Suitable for concurrent-channel data streaming with simple MCU interface
- Available in LPZ leadless/package format
Note: Always check the latest datasheet for exact specs (temp range, throughput, reference options, and package details).

Pinout

- Pin count: 16 pins (16-pin package)
- Function: Analog-to-digital converter — dual channel with two analog inputs and a serial (SPI-compatible) interface.

Manufacturer

Analog Devices, Inc. (ADI) manufactures the AD7225LPZ. ADI is an American multinational semiconductor company that designs and makes analog, mixed-signal, and DSP integrated circuits (e.g., data converters, amplifiers, sensors, signal-processing ICs).

Application

Possible application areas for AD7225LPZ:
- Data acquisition systems with multiple analog inputs
- Industrial process control and automation
- Instrumentation and measurement equipment
- Medical and portable diagnostic devices
- Automotive sensor interfaces and monitoring
- Test & measurement equipment and data loggers
These cover multi-channel sensing, conditioning, and digitization needs typical of AD7225LPZ.

Package

28‑pin RoHS-compliant Plastic Leaded Chip Carrier (LQFP) style package.
