Overview
The AD7811YR-REEL is a high-speed, low-power 10-bit analog-to-digital converter manufactured by Analog Devices Inc. It features four single-ended input channels that can be configured as three pseudo-differential inputs or two independent pseudo-differential pairs. The device operates from a single 2.7 V to 5.5 V supply and includes an onboard track-and-hold amplifier and a 2.5 V reference circuit. It utilizes a successive approximation architecture with a conversion time of 2.3 µs and supports throughput rates up to 350 kSPS. The component is housed in a 16-lead Small Outline IC (SOIC) package.
Feature Summary
- Configurable multi-channel input support allowing selection between single-ended and pseudo-differential modes via control registers.
- Integrated onboard voltage reference and track-and-hold amplifier for simplified system design.
- DSP-compatible serial interface enabling direct connection to microcontrollers and digital signal processors.
- Hardware and software control options for automatic power-down modes to optimize energy consumption.
Applications
- Industrial process control systems requiring multi-channel data acquisition.
- Automotive applications qualified for automotive standards.
- Portable instrumentation powered by single-supply batteries.
- Data acquisition modules interfacing with DSPs or microcontrollers.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details. The REEL suffix indicates tape and reel packaging intended for automated surface-mount assembly. Confirm RoHS compliance status and lead-free specifications directly with the supplier or official datasheet before procurement.
Selection Notes
Select this component when a 10-bit resolution with four configurable input channels is required. Ensure the application voltage range falls within the 2.7 V to 5.5 V specification. Consider the SOIC-16 package dimensions for PCB layout constraints. Verify that the serial interface timing requirements align with the host processor's clock capabilities.
Part Context
This part belongs to the AD7811/AD7812 family of sampling ADCs. The AD7811 variant specifically provides four input channels, whereas the AD7812 offers eight. Both share identical core architectures, including the SAR converter and serial interface. The Y version denotes the specified linearity error performance.
Replacement Considerations
The AD7811YR is the non-reel equivalent of this part number. Other variants include the AD7811YN (DIP) and AD7811YRU (TSSOP). Cross-model substitution with the AD7812 requires accounting for the additional input channels and different pin count.
