AD7914BRUZ-REEL7

Overview

The AD7914BRUZ-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 for automated multi-channel conversion. It utilizes a flexible high-speed serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Power consumption is optimized at 6 mW maximum at 1 MSPS with 3 V supplies and 13.5 mW maximum with 5 V supplies. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Integrated channel sequencer enables automated sequential conversion of multiple single-ended input channels without external control overhead.
• Flexible power management includes auto-shutdown and full-shutdown modes to minimize current draw during idle periods.
• VDRIVE function allows the digital interface logic levels to operate independently of the analog supply voltage.
• No pipeline delay architecture ensures accurate timing control via the CS input for immediate data acquisition.

Applications

• Industrial process control systems requiring multi-point temperature or pressure monitoring
• Battery-powered instrumentation utilizing low-power sampling capabilities
• Data acquisition modules interfacing with microprocessors or DSPs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and automotive qualification status. Ensure the requested reel quantity matches the standard packaging specifications provided in the datasheet. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate resolution and high speed is required for multi-channel applications. The 10-bit resolution suits general-purpose signal conditioning tasks. Consider the available channel count and the need for internal sequencing to simplify system design. Evaluate power constraints to determine if the shutdown modes meet energy efficiency targets.

Part Context

This part belongs to the AD7904/AD7914/AD7924 family of high-speed, low-power ADCs. The family shares identical pinouts and functional architectures, differing primarily in resolution: 8-bit, 10-bit, and 12-bit respectively. The AD7914 serves as the mid-range option within this series, offering higher precision than the AD7904 while maintaining lower power consumption compared to the 12-bit AD7924.

Replacement Considerations

The AD7904BRUZ and AD7924BRUZ are direct pin-compatible alternatives within the same family, offering 8-bit and 12-bit resolutions respectively. For automotive applications, the AD7914WYRUZ variant provides extended temperature range qualification. Verify that the replacement meets the specific resolution and thermal requirements of the target design.
