AD7894ARZ-3REEL7

Overview

The AD7894ARZ-3REEL7 is a 14-bit successive approximation analog-to-digital converter (ADC) housed in an 8-lead SOIC package. It operates from a single +5 V supply and features an on-chip track/hold amplifier, internal clock, and high-speed serial interface. The device supports a bipolar input voltage range of -2.5 V to +2.5 V and requires an external +2.5 V reference. Typical power consumption is 20 mW, with a maximum conversion time of 5 µs in Mode 1 operation. It offers a signal-to-noise ratio of 77 dB minimum and differential nonlinearity of ±1.5 LSB.

Feature Summary

Integrated on-chip track/hold amplifier for accurate signal acquisition
High-speed two-wire serial interface for data output
Automatic power-down mode for low-power applications
Single +5 V supply operation capability

Applications

Battery-powered portable instrumentation
Industrial process control systems
Data acquisition modules requiring 14-bit resolution

Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when sourcing components. Confirm that the AD7894-3 designation corresponds to the required -2.5 V to +2.5 V input range. Ensure the external reference voltage matches the specified +2.5 V requirement for optimal performance.

Selection Notes

Select this component when a compact 14-bit ADC with a small 8-lead footprint is required. Choose the AD7894ARZ-3 variant specifically for bipolar input signals within the -2.5 V to +2.5 V range. Consider the automatic power-down feature if battery life is a critical design constraint.

Part Context

This part belongs to the AD7894 family of fast, 14-bit serial ADCs. It serves as a pin-compatible upgrade to the 12-bit AD7895. The 'ARZ' designation indicates an industrial temperature range (-40°C to +85°C) and RoHS compliance. The suffix '3' defines the specific analog input voltage range for this device.

Replacement Considerations

The AD7894ARZ-3 is a direct replacement for the AD7894AR-3. Verify compatibility with existing PCB footprints as both utilize the 8-lead SOIC package.
