AD7828LP-REEL

Overview

The AD7828LP-REEL is an 8-bit, high-speed analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features eight multiplexed analog input channels and utilizes a half-flash conversion architecture for rapid data acquisition. The device operates from a single 5 V supply with an analog input range of 0 V to 5 V. Key electrical parameters include a sampling rate of 400 kS/s per channel, a conversion time of 2.5 µs, and a power dissipation of 25 mW. It integrates a built-in track-and-hold function capable of handling full-scale signals up to 10 kHz.

Feature Summary

• Eight multiplexed analog input channels with a single-ended input type
• Half-flash architecture providing a fast conversion rate of 2.5 µs per channel
• Built-in track-and-hold function supporting 10 kHz signal handling
• Single 5 V power supply operation with low power consumption of 25 mW

Applications

• High-speed multi-channel data acquisition systems
• Industrial process control monitoring
• Portable instrumentation requiring single-supply operation
• Battery-powered measurement devices

Part Context

The AD7828LP-REEL belongs to the AD7828 family of LC2MOS high-speed ADCs. The 'LP' suffix indicates a plastic package variant, while '-REEL' specifies the tape-and-reel packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

The AD7828BR serves as a pin-compatible alternative within the same family. Designers should verify that the replacement component meets the specific temperature grade and package requirements of the original design.
