Overview
The AD7914BRU-REEL7 is a 10-bit, 4-channel successive approximation analog-to-digital converter (ADC) from Analog Devices. It operates on a single supply voltage ranging from 2.7 V to 5.25 V and supports throughput rates up to 1 MSPS. The device features four single-ended analog inputs with an integrated channel sequencer. It utilizes a flexible serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Power consumption reaches a maximum of 13.5 mW at 5 V supplies during operation.
Feature Summary
- Integrated channel sequencer for automated sequential conversion of multiple single-ended inputs
- VDRIVE function enabling direct connection to 3 V or 5 V processor systems independent of AVDD
- Flexible power management with full shutdown mode reducing current consumption to 0.5 µA maximum
- Standard successive approximation architecture eliminating pipeline delays
Applications
- Industrial process control systems requiring multi-channel data acquisition
- Battery-powered instrumentation utilizing low-power SAR ADC technology
- Automotive sensor interfaces meeting AEC-Q100 qualification standards
- Data logging applications involving sequential monitoring of single-ended signals
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the REEL7 designation corresponds to tape-and-reel packaging quantities. Ensure compatibility with existing board layouts regarding the 16-lead TSSOP footprint and pin assignments before finalizing procurement orders.
Selection Notes
Select this component when a 10-bit resolution is required for four single-ended channels. Verify that the input signal range aligns with the external reference voltage capabilities. Consider the VDRIVE pin configuration if interfacing with logic levels different from the analog supply voltage. Evaluate power constraints against the specified operational and shutdown modes.
Part Context
This part belongs to the AD7904/AD7914/AD7924 family of high-speed, low-power ADCs. The series shares identical pinouts and functional blocks, differing primarily in resolution: 8-bit, 10-bit, and 12-bit respectively. All variants support the same 1 MSPS throughput rate and utilize the same 16-lead TSSOP package configuration.
Replacement Considerations
The AD7914WYRUZ serves as a qualified automotive-grade alternative within the same family. Both parts share identical electrical specifications and pinouts but differ in operating temperature ranges and qualification standards.
