AD5696ARUZ-RL7

Overview

The AD5696ARUZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an I2C-compatible serial interface and operates on a single 2.7 V to 5.5 V supply. The device provides high relative accuracy with a maximum integral nonlinearity (INL) of ±2 LSB at 16 bits. Key specifications include a total unadjusted error (TUE) of ±0.1% FSR, offset error of ±1.5 mV, and gain error of ±0.1% FSR. It offers user-selectable gain of 1 or 2 via the GAIN pin, allowing full-scale outputs of 0 V to VREF or 0 V to 2 × VREF. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Quad 16-bit resolution with ±2 LSB maximum INL
• I2C-compatible 2-wire serial interface supporting up to 400 kHz clock rates
• User-selectable gain (1 or 2) for flexible output voltage ranges
• Low power consumption: 1.8 mW at 3 V; 4 µA in power-down mode

Applications

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

Procurement Notes

Verify the specific grade (A or B) required for your application, as performance parameters like INL vary between grades. Confirm that the 'RL7' suffix indicates reel packaging. Ensure the design supports the 16-lead TSSOP footprint and accounts for the exposed pad grounding requirements if using alternative packages in the same series.

Selection Notes

Select this component when four independent 16-bit voltage outputs are needed with I2C connectivity. Ensure the external reference voltage (VREF) aligns with the desired output span, considering the GAIN pin configuration. Verify that the logic voltage (VLOGIC) matches the host microcontroller's I/O levels, as it supports 1.8 V, 3 V, and 5 V logic.

Part Context

This part belongs to the AD5696/AD5694 family, which includes 16-bit and 12-bit variants. The AD5696ARUZ-RL7 specifically denotes the A-grade 16-bit version in a TSSOP-16 package, supplied in a reel. Other package options for the AD5696 include the 3 mm × 3 mm LFCSP. The 'R' variant typically implies an internal reference, but the datasheet indicates the AD5696 uses an external reference input (VREF), distinguishing it from the AD5696R.

Replacement Considerations

Direct substitutes within the same family include the AD5696BRUZ-RL7 (B-grade) or the AD5696ACPZ-RL7 (LFCSP package). For lower resolution needs, the AD5694 series offers 12-bit performance. Ensure any replacement maintains the I2C interface compatibility and TSSOP-16 form factor.
