AD5662ARJ-2REEL7

Overview

The AD5662ARJ-2REEL7 is a single-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices' nanoDAC family. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a rail-to-rail buffered output amplifier. The device guarantees 12-bit accuracy and is monotonic by design. Key electrical parameters include a maximum settling time of 10 μs, a typical power consumption of 250 μA at 5 V, and a power-down current as low as 100 nA at 3 V. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz.

Feature Summary

• 16-bit resolution with guaranteed 12-bit accuracy and monotonicity by design
• Rail-to-rail output swing with an integrated buffered amplifier
• Power-on reset circuit configured for midscale output initialization
• Low power operation: 250 μA active current; 480 nA in power-down mode at 5 V

Applications

• Process control systems requiring precise analog signal generation
• Portable battery-powered instruments due to ultra-low power consumption
• Data acquisition systems needing high-resolution voltage references
• Programmable voltage and current sources for industrial automation

Procurement Notes

Verify the ordering suffix '-2' confirms the power-on reset behavior targets midscale upon startup. Confirm the package type matches the SOT-23-8 form factor specified for this variant. Ensure the reel packaging quantity aligns with production requirements. Check RoHS compliance status against current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, high-resolution DAC with rail-to-rail output is required in a compact SOT-23 package. The external reference input necessitates pairing with a precision voltage reference IC for optimal accuracy. Consider the 10 μs settling time for bandwidth limitations in dynamic applications. Evaluate the 3-wire interface compatibility with the host microcontroller's available serial ports.

Part Context

This part belongs to the AD5662 nanoDAC family, which offers various configurations including different resolutions and package types. The 'ARJ' designation indicates the specific SOT-23-8 package variant, while the '-2' suffix defines the power-on reset state. Related devices in the series include the AD5660 and AD5663, offering alternative pinouts or channel counts within the same architectural framework.

Replacement Considerations

Direct replacements must maintain the 16-bit resolution, SOT-23-8 package, and midscale power-on reset feature. Verify that any substitute supports the same 2.7 V to 5.5 V supply range and 3-wire serial interface timing specifications. Ensure thermal impedance and power dissipation characteristics are comparable for the target application environment.
