AD5678BRUZ-2REEL7

Overview

The AD5678BRUZ-2REEL7 is an octal digital-to-analog converter featuring four 12-bit and four 16-bit channels in a single package. It operates on a single 2.7 V to 5.5 V supply and includes an on-chip 2.5 V reference with 5 ppm/°C temperature coefficient, yielding a 5 V full-scale output. The device guarantees monotonicity by design and incorporates a power-on reset circuit that ensures outputs initialize to 0 V. It supports a versatile 3-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP standards, with clock rates up to 50 MHz.

Feature Summary

• Octal architecture combining four 12-bit and four 16-bit DACs
• On-chip 2.5 V precision reference (5 ppm/°C) for 5 V full-scale output
• Power-down current consumption of 400 nA at 5 V and 200 nA at 3 V
• Rail-to-rail buffered voltage outputs with simultaneous LDAC update capability

Applications

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

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when sourcing components. Confirm the '-2' designation corresponds to the 2.5 V internal reference variant. Ensure compatibility with the required TSSOP footprint during procurement planning.

Selection Notes

Select this component for applications requiring mixed-resolution outputs within a single package. The -2 suffix provides a fixed 5 V full-scale range via the internal reference; use external references if different voltage ranges are needed. Verify that the 16-bit accuracy meets system requirements for the primary channels.

Part Context

This part belongs to the AD5678 family of low-power octal DACs. It shares functional similarities with the AD5668 and AD5672 series but is distinct due to its mixed 12-bit and 16-bit channel configuration. The device is designed for industrial environments with an operating temperature range of -40°C to +105°C.

Replacement Considerations
