Overview
The AD7827BR-REEL is an 8-bit, single-channel analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 3 V or 5 V supply and achieves a maximum throughput of 1 MSPS with a conversion time of 420 ns. The device integrates a track-and-hold amplifier, a half-flash ADC architecture, and a serial interface compatible with DSPs. It features an on-chip 2.5 V reference with 2% tolerance and automatic power-down capabilities. The component is housed in an 8-lead SOIC package.
Feature Summary
- Integrates a track-and-hold amplifier for precise signal sampling
- Features a half-flash ADC architecture for rapid conversion
- Includes an on-chip 2.5 V voltage reference
- Supports automatic power-down to minimize energy consumption
Applications
- Direct interfacing with Digital Signal Processors (DSPs)
- High-speed data acquisition systems
- Real-time signal processing applications
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing this component. Confirm that the B version meets the required industrial temperature range specifications. Ensure compatibility with the intended serial clock frequencies and logic levels before finalizing procurement orders.
Selection Notes
Select this model for applications requiring high-speed 8-bit resolution with low power consumption. Consider the integrated reference if external components are undesirable. Verify that the input voltage range aligns with the chosen supply voltage, as it scales between 0 V to 2 V and 0 V to 2.5 V.
Part Context
This component belongs to the AD7827 series of sampling ADCs. It is designed for environments where speed and power efficiency are critical. The BR variant specifically denotes the Small Outline IC package option within the product line.
Replacement Considerations
Check for updated revisions of the AD7827 series. Evaluate other 8-bit SAR ADCs from Analog Devices if pin compatibility is not required. Verify functional equivalence regarding serial interface timing and power-down modes.
