AD5686ARUZ-RL7

Overview

The AD5686ARUZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an SPI interface with readback capability and operates on a single 2.7 V to 5.5 V supply. The device includes a power-on reset circuit and a RSTSEL pin for configurable startup states. Key electrical parameters include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 5 µs, and a low glitch impulse of 0.5 nV-sec. It supports user-selectable gain of 1 or 2 via the GAIN pin, allowing full-scale outputs of 2.5 V or 5 V respectively.

Feature Summary

• Quad 16-bit resolution with ±2 LSB maximum INL
• SPI interface supporting up to 50 MHz clock rates
• Integrated power-on reset and hardware LDAC mask register
• Low power consumption: 1.8 mW at 3 V

Applications

• Digital gain and offset adjustment
• Programmable attenuators
• Process control I/O cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for the assembly line. Confirm that the A-grade performance specifications meet the design requirements for integral nonlinearity and offset error drift within the operating temperature range of -40°C to +105°C.

Selection Notes

Select this component when high relative accuracy and low power are critical. Ensure the system logic voltage is compatible with the 1.8 V to 5.5 V VLOGIC range. Consider the TSSOP-16 package dimensions for PCB layout constraints. Verify that the capacitive load stability limits (2 nF without resistive load) are respected in the application circuit.

Part Context

This part belongs to the AD5686/AD5684 nanoDAC+ family, which offers quad-channel configurations in both 16-bit and 12-bit resolutions. The AD5686 variant specifically provides 16-bit precision. The family shares common interface protocols and pinouts, facilitating design scalability across different accuracy requirements.
