AD7914WYRUZ-REEL7

Overview

The AD7914WYRUZ-REEL7 is a 10-bit, 4-channel successive approximation analog-to-digital converter (ADC) from Analog Devices. It operates with 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 managed by an internal channel sequencer. It utilizes a flexible serial interface compatible with SPI, QSPI, Microwire, and DSP standards. The component is housed in a 16-lead TSSOP package and is qualified for automotive applications.

Feature Summary

• Integrated channel sequencer allows pre-programmed sequential conversion of multiple single-ended analog inputs.
• VDRIVE function enables the serial interface to operate independently of the analog supply voltage.
• Flexible power management includes auto shutdown and full shutdown modes to minimize current consumption.

Applications

• Automotive data acquisition systems
• Industrial process control monitoring
• Battery-powered measurement instruments

Procurement Notes

Verify that the specific ordering suffix matches the required temperature range and packaging format. Confirm that the W version designation aligns with automotive qualification requirements if applicable. Ensure the reel quantity meets production needs. Cross-reference the datasheet revision to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a low-power, high-speed solution with multiple input channels is required. The 10-bit resolution balances accuracy and speed for general-purpose applications. Consider the external reference requirement and the available input voltage ranges when designing the signal conditioning stage. Verify compatibility with the host microprocessor's serial clock speeds.

Part Context

This part belongs to the AD7904/AD7914/AD7924 family of 8-, 10-, and 12-bit ADCs. The AD7914 specifically provides 10-bit resolution, distinguishing it from the 8-bit AD7904 and the 12-bit AD7924 within the same package and feature set. All variants share identical pinouts and functional blocks.

Replacement Considerations

The AD7914BRUZ serves as a commercial grade alternative within the same package. The AD7914WYRUZ is the non-reel variant of the same automotive qualified component. Substitution requires verification of the specific temperature rating and packaging preference.
