AD5662ARMZ-1REEL7

Overview

The AD5662ARMZ-1REEL7 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single supply ranging from 2.7 V to 5.5 V and consumes 250 μA at 5 V. The device guarantees 12-bit accuracy with a maximum settling time of 10 μs. It features a power-on reset circuit that initializes the output to zero scale upon startup. The DAC 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 monotonicity by design
• Power-on reset to zero scale for AD5662x-1 variants
• Rail-to-rail output capability in an 8-lead MSOP package
• Three software-selectable power-down modes reducing current to 480 nA

Applications

• Process control systems
• Portable battery-powered instruments
• Programmable voltage and current sources
• Digital gain and offset adjustment circuits

Procurement Notes

Verify the ordering suffix '1' confirms the zero-scale power-on reset function. Confirm the 'REEL7' designation indicates tape-and-reel packaging containing 3000 units. Ensure the 'ARMZ' suffix corresponds to the MSOP-8 package variant required for the specific PCB layout constraints.

Selection Notes

Select this component when a single-channel 16-bit DAC with rail-to-rail output is required. The external reference input allows flexibility in setting the output range. Consider the 10 μs settling time and 250 μA active current consumption against system power budgets and speed requirements.

Part Context

This part belongs to the nanoDAC family, designed for low-power applications. It shares architectural similarities with other members like the AD5660 and AD5663 but differs in channel count and specific reset behaviors defined by the ordering suffix.
