AD5696RARUZ-RL7

Overview

The AD5696RARUZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device provides four independent channels with a settling time of 5 µs and supports a 400 kHz I2C-compatible serial interface. Key specifications include ±2 LSB maximum relative accuracy (INL), ±0.1% FSR total unadjusted error, and a high drive capability of 20 mA. It is housed in a 16-lead TSSOP package and functions within a temperature range of −40°C to +105°C.

Feature Summary

• Quad 16-bit resolution with ±2 LSB maximum INL and 5 µs settling time
• Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient
• User-selectable gain of 1 or 2 via GAIN pin for flexible output ranges
• Per-channel power-down mode reducing current consumption to 4 µA at 3 V

Applications

• Optical transceivers
• Base-station power amplifiers
• Process control (PLC I/O cards)
• Industrial automation
• Data acquisition systems

Procurement Notes

Verify the specific suffix RL7 corresponds to the reel packaging configuration as indicated by distributor listings. Confirm that the RARUZ designation aligns with the required 16-lead TSSOP package and operating temperature grade. Ensure compatibility with the intended I2C bus addressing scheme using the A0 and A1 pins.

Selection Notes

Select this component when a quad-channel solution with high precision (16-bit) and low drift is required. The internal reference simplifies design compared to external reference variants. Consider the GAIN pin configuration to determine if the 0–2.5 V or 0–5 V output span meets system requirements. Verify that the 20 mA drive capability is sufficient for the connected load impedance.

Part Context

This part belongs to the AD5696R/AD5695R/AD5694R family, which shares identical pinouts and functional blocks but differs in resolution. The AD5696R specifically offers 16-bit performance, whereas the AD5695R provides 14 bits and the AD5694R provides 12 bits. All variants utilize the same I2C interface and package options.

Replacement Considerations

The AD5696BCPZ-RL7 serves as a direct replacement offering identical electrical specifications but utilizes a 16-lead LFCSP package instead of TSSOP. Other family members like the AD5695R or AD5694R may be used if lower resolution is acceptable.
