AD5675BRUZ-REEL7

Overview

The AD5675BRUZ-REEL7 is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a user-selectable gain of 1 or 2, allowing full-scale outputs of VREF or 2 × VREF. The device operates on a single 2.7 V to 5.5 V supply and includes a power-on reset circuit with RSTSEL pin control for zero or midscale initialization. It utilizes a versatile 2-wire I2C-compatible serial interface supporting clock rates up to 400 kHz. The B grade ensures a maximum integral nonlinearity (INL) of ±3 LSB and a total unadjusted error (TUE) of ±0.14% of FSR.

Feature Summary

• Octal architecture with eight independent 16-bit DAC channels in a 20-lead TSSOP package.
• High relative accuracy with ±3 LSB maximum INL and ±0.14% maximum TUE at 16 bits.
• User-selectable gain configuration via GAIN pin or bit for spans of VREF or 2 × VREF.
• Integrated power-down mode reducing current consumption to 1 µA typical.

Applications

• Optical transceivers
• Base station power amplifiers
• Process control PLC input/output cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix REEL7 corresponds to tape and reel packaging containing 1000 units. Confirm the B grade designation matches the required ±3 LSB INL specification. Ensure the 20-lead TSSOP footprint aligns with the PCB layout guidelines provided in the datasheet. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this component when multiple high-resolution analog outputs are required within a compact form factor. The internal reference input range supports operation down to VDD/2 for gain = 2 configurations. Verify that the load impedance requirements, such as the 1 kΩ resistive load limit, fit the application design. Consider the 1.8 V logic compatibility if interfacing with low-voltage microcontrollers.

Part Context

This part belongs to the nanoDAC+ family, which integrates precision DACs with onboard buffers. The AD5675 differs from the AD5676 by using an I2C interface instead of SPI. The BRUZ suffix indicates the B grade performance level and the 20-lead TSSOP package type. The REEL7 suffix denotes the specific reel packaging format for automated assembly.

Replacement Considerations

The AD5675ARUZ-REEL7 serves as a direct replacement offering A grade performance with tighter linearity specifications (±1.8 LSB INL). Both parts share identical pinouts and software commands, ensuring drop-in compatibility for system upgrades requiring higher precision.
