AD7927BRUZ-REEL

Overview

The AD7927BRUZ-REEL is an 8-channel, 12-bit successive approximation analog-to-digital converter (ADC) housed in a 20-lead TSSOP package. It operates from a single 2.7 V to 5.25 V supply and supports throughput rates up to 200 kSPS. The device features a wide input bandwidth track-and-hold amplifier capable of handling input frequencies exceeding 8 MHz. Key electrical specifications include a minimum Signal-to-Noise Ratio (SNR) of 70 dB at 5 V, integral nonlinearity of ±1 LSB maximum, and differential nonlinearity of -0.9/+1.5 LSB maximum. Power consumption reaches a maximum of 7.5 mW at 5 V and 3.6 mW at 3 V during operation.

Feature Summary

• Eight single-ended analog inputs with a programmable channel sequencer for automated sequential conversion cycles.
• Flexible power management modes including normal operation, auto shutdown, and full shutdown to optimize energy efficiency based on throughput requirements.
• VDRIVE function enabling the serial interface to operate independently at either 3 V or 5 V logic levels regardless of the analog supply voltage.

Applications

• Industrial process control systems requiring multi-channel data acquisition.
• Automotive sensor interfaces and monitoring circuits.
• Portable instrumentation utilizing battery-powered single-supply architectures.

Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and packaging format. Confirm that the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for automotive qualification marks if operating in harsh environments. Validate pin compatibility with the target PCB footprint before finalizing procurement.

Selection Notes

Select this component when eight single-ended channels are required within a compact surface-mount footprint. Ensure the application can accommodate an external reference voltage of 2.5 V for specified performance. Verify that the host microprocessor supports the required SPI-compatible serial interface timing. Consider the 20-lead TSSOP thermal characteristics for high-density board layouts.

Part Context

This part belongs to the AD7927 family of high-speed, low-power ADCs manufactured by Analog Devices Inc. The BRUZ variant specifically denotes the commercial temperature range (-40°C to +85°C) and the TSSOP-20 package style. It serves as a cost-effective solution for applications needing moderate resolution across multiple channels without pipeline delay latency.
