AD5426YRMZ-REEL7

Digital To Analog Converters Overview

The AD5426YRMZ-REEL7 is an 8-bit current-output digital-to-analog converter (DAC) from Analog Devices Inc., operating on a CMOS submicron process. It supports a supply voltage range of 2.5 V to 5.5 V and features a 50 MHz serial interface compatible with SPI, QSPI, and MICROWIRE standards. The device offers a multiplying bandwidth of 10 MHz and an update rate of 2.5 MSPS. Key performance metrics include an integral nonlinearity (INL) of ±1 LSB for the 12-bit variant family context, though specific to this 8-bit model, relative accuracy is ±0.25 LSB. It operates within an extended temperature range of −40°C to +125°C and consumes typical power of 0.4 µA.

Digital To Analog Converters Feature Summary

• 8-bit resolution with ±0.25 LSB relative accuracy and guaranteed monotonicity
• 50 MHz serial interface supporting daisy-chain mode and data readback via SDO pin
• 10 MHz reference multiplying bandwidth with low glitch energy (< 2 nV-s)
• Extended industrial temperature range (−40°C to +125°C) in a 10-lead MSOP package

Digital To Analog Converters Applications

• Portable battery-powered applications due to low power consumption
• Waveform generators requiring high-speed updating
• Programmable amplifiers and attenuators using 4-quadrant multiplication
• Digitally controlled calibration systems
• Ultrasound imaging signal processing

Digital To Analog Converters Procurement Notes

Verify the ordering suffix REEL7 confirms tape-and-reel packaging when sourcing components. Confirm the Y suffix indicates the extended temperature grade (−40°C to +125°C). Ensure compatibility with system logic levels, as input thresholds vary with supply voltage. Check for pin-out alignment if replacing legacy parts, as this device is part of a pin-compatible family including 10-bit and 12-bit variants.

Digital To Analog Converters Selection Notes

Select the AD5426 specifically for 8-bit resolution requirements; higher precision needs may require the AD5432 (10-bit) or AD5443 (12-bit). Consider the 10 MHz multiplying bandwidth for AC reference applications. Verify that the external amplifier can handle the output capacitance variations (12–17 pF at IOUT1) to maintain stability. Ensure the system design accommodates the ±10 V reference input range and the integrated feedback resistor characteristics.

Digital To Analog Converters Part Context

This component belongs to the AD5426/AD5432/AD5443 family of high-bandwidth multiplying DACs. These devices share identical pinouts and functional blocks, differing primarily in resolution (8, 10, and 12 bits respectively). The AD5426 serves as the entry-level option for cost-sensitive or lower-resolution applications within this series, maintaining the same serial interface and performance characteristics as its higher-resolution counterparts.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same package are the AD5432YRMZ and AD5443YRMZ, offering 10-bit and 12-bit resolutions respectively. When substituting, verify that the increased resolution meets system requirements without necessitating layout changes. No other manufacturer cross-references are publicly confirmed in the datasheet.
