AD7893ARZ-10REEL

Overview

The AD7893ARZ-10REEL is a 12-bit successive approximation analog-to-digital converter (ADC) fabricated in LC2MOS technology. 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 a high-speed serial interface requiring only two wires. It accepts a bipolar analog input range of ±10 V with a maximum conversion time of 6 μs and a throughput rate up to 117 kHz. The part is housed in an 8-pin SOIC package.

Feature Summary

• Integrates a fast 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 portable applications.
• Provides a high-speed, easy-to-use two-wire serial interface for data output.

Applications

• Battery-powered or portable electronic systems
• Industrial process control monitoring
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure the external reference voltage matches the required +2.5 V specification for optimal performance. Confirm that the reel packaging aligns with automated assembly requirements.

Selection Notes

Select this component when a compact 12-bit resolution is required with a ±10 V input range. Verify system timing constraints allow for the 6 μs conversion time and 1.5 μs acquisition time. Ensure the host microcontroller supports the required serial clock frequencies and data format.

Part Context

This model belongs to the AD7893 family of single-supply ADCs. Variants differ by input range and package style. The ARZ designation indicates an 8-pin SOIC package with RoHS compliance. Other suffixes may denote different linear accuracy grades or hermetic packages.

Replacement Considerations

Check for pin-compatible upgrades such as the AD7894 series for higher resolution. Verify if alternative SAR ADCs meet the specific ±10 V input requirement without additional scaling circuitry.

FAQ

What is the analog input voltage range for the AD7893-10 variant?

The AD7893-10 variant accepts a bipolar analog input voltage range of ±10 V.

How is the conversion process initiated?

Conversion is initiated on the rising edge of the CONVST input signal, which triggers the track/hold amplifier to enter hold mode.

What is the typical power dissipation of the device?

The typical power dissipation is 25 mW when operating from a single +5 V supply.
