AD7893ARZ-5REEL

Overview

The AD7893ARZ-5REEL is a 12-bit successive approximation analog-to-digital converter (ADC) fabricated in Analog Devices' LC2MOS process. It operates from a single +5 V supply and consumes 25 mW typically. The device features an on-chip track/hold amplifier, internal clock, and high-speed serial interface. It accepts a unipolar input voltage range of 0 V to +5 V with a minimum input resistance of 9 kΩ. Conversion time is 6 μs maximum, supporting throughput rates up to 117 kHz. The part provides straight binary output coding and requires an external +2.5 V reference.

Feature Summary

• Integrates a 12-bit ADC, track/hold amplifier, and control logic within an 8-pin package for space efficiency.
• Operates from a single +5 V supply with low power consumption suitable for battery-powered applications.
• Utilizes a two-wire serial interface consisting of SCLK and SDATA lines for simplified microcontroller connectivity.

Applications

• Battery-powered portable instrumentation
• Industrial data acquisition systems
• Process control monitoring

Procurement Notes

Verify the specific suffix '5REEL' against official documentation to confirm it denotes the SOIC-8 tape and reel packaging variant. Ensure the ordering code matches the required temperature range and linearity specifications. Confirm RoHS compliance status through the manufacturer's current product release notes before finalizing procurement orders.

Selection Notes

Select this component when a 12-bit resolution and 0 V to +5 V input range are required in a compact form factor. The AD7893-5 variant is appropriate for unipolar signal conditioning. Consider the 6 μs conversion time and 117 kHz throughput rate against system timing requirements. Verify that the external reference voltage can be stabilized at +2.5 V for optimal accuracy.

Part Context

The AD7893 belongs to a family of fast, single-supply A/D converters available in multiple input ranges. The ARZ designation indicates the SOIC-8 package option. This series combines precision bipolar circuits with low-power CMOS logic to deliver high performance in a minimal footprint, distinguishing it from parallel interface alternatives.
