Description

The AD7868BRZ is a high-performance, low-power, 8-channel, 12-bit analog-to-digital converter (ADC) designed by Analog Devices. It features a successive approximation architecture, allowing it to convert analog signals to digital form with high accuracy. The device operates with a single supply voltage ranging from 2.7V to 5.25V and supports an internal reference voltage.
Key features include a sampling rate of up to 100 kSPS and a parallel interface for fast data transfer, making it suitable for various applications, including industrial process control, medical instrumentation, and data acquisition systems. The AD7868BRZ also includes features like internal track-and-hold circuitry, low power consumption (typical operating current of around 500 µA), and a built-in power-down mode.
Overall, the AD7868BRZ is ideal for applications requiring precise and efficient analog signal conversion in compact, battery-operated devices.

Features

The AD7868BRZ is a 12-bit, 8-channel, successive approximation analog-to-digital converter (ADC) designed for various applications. Key features include:
1. Resolution: 12-bit conversion for high precision.
2. Channels: Supports up to 8 single-ended inputs or 4 differential inputs.
3. Sampling Rate: Capable of a maximum sampling rate of 100 kSPS.
4. Power Supply: Operates on a single +5V supply, with low power consumption.
5. Interface: Provides a serial SPI-compatible digital interface for easy integration.
6. Internal Reference: Includes an internal voltage reference, simplifying the design.
7. Low Noise: Features low noise and low offset voltage for accurate measurements.
8. Temperature Range: Operates over a wide industrial temperature range (-40°C to +85°C).
These features make the AD7868BRZ suitable for applications in portable instrumentation, data acquisition systems, and industrial monitoring.

Package

The AD7868BRZ is packaged in a 20-lead LFCSP (Lead Frame Chip Scale Package) with a standard size of 5mm x 5mm.

Pinout

The AD7868BRZ is an integrated precision analog-to-digital converter (ADC) with a total of 28 pins. It features a 16-bit resolution and operates with a 2.5V reference voltage. Key functions include:
1. Power Supply Pins: VDD and VSS for powering the device.
2. Analog Input Pins: Multiple channels (typically 8) for differential or single-ended signal inputs.
3. Digital Output Pins: Data output pins (D0-D15) for the 16-bit digital data.
4. Control Pins: Pins for chip select (CS), read (RD), and write (WR) operations to manage data transfer and configuration.
5. Clock Input: A clock pin (CLK) to synchronize data conversion.
6. Reference Voltage Pins: REF pin for setting the reference voltage.
7. Ground Pins: GND for the common ground connection.
The AD7868 is designed for applications requiring high precision, such as industrial control, medical devices, and data acquisition systems.
