AD5392BSTZ-5

Digital To Analog Converters Overview

The AD5392BSTZ-5 is an 8-channel, 14-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single supply with AVDD ranging from 2.7 V to 5.5 V and DVDD from 2.7 V to 5.5 V. The device features rail-to-rail output amplifiers, a programmable internal reference of 1.25 V or 2.5 V, and guaranteed monotonicity. Relative accuracy is ±3 LSB max for the -5 version. It supports SPI, QSPI, MICROWIRE, DSP, and I²C interfaces, includes channel monitoring, power-down modes, and operates within a temperature range of −40°C to +85°C.

Digital To Analog Converters Feature Summary

• 8-channel, 14-bit resolution with rail-to-rail output amplifiers
• Integrated 1.25 V/2.5 V reference source with 10 ppm/°C drift
• Dual serial interface: SPI/QSPI/MICROWIRE/DSP (>30 MHz) and I²C (400 kHz)
• Programmable gain and offset adjustment registers per channel

Digital To Analog Converters Applications

• Instrumentation and industrial control systems
• Power amplifier control circuits
• Level setting in automated test equipment (ATE)
• Variable optical attenuators (VOAs)
• Optical transceivers (MSA 300, XFP)

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BSTZ-5' against the manufacturer's current ordering guide to confirm package type (LQFP vs LFCSP) and revision status. Ensure compatibility with system voltage requirements (AVDD 2.7V–5.5V, DVDD 2.7V–5.5V). Check for RoHS compliance and lead-free status as indicated by the 'Z' suffix in official documentation.

Digital To Analog Converters Selection Notes

Select the AD5392BSTZ-5 when 8 channels of 14-bit precision are required with simultaneous update capabilities via LDAC. Consider the -5 suffix variant if operating with a 2.5 V external reference for optimal accuracy (±3 LSB INL). Use the -3 variant if operating with a 1.25 V reference. Ensure the host controller supports the desired serial protocol (SPI or I²C) and can handle the double-buffered input/DAC register architecture.

Digital To Analog Converters Part Context

The AD5392 is part of the AD5390/AD5391/AD5392 family of single-supply DACs. While the AD5390 offers 16 channels at 14 bits and the AD5391 offers 16 channels at 12 bits, the AD5392 provides a compact 8-channel solution. All members share similar architectural features, including the integrated reference, monitor function, and serial interface options.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5390BSTZ-5 (16-channel) and AD5391BSTZ-5 (16-channel), though channel count differs. Verify that any substitute maintains the 14-bit resolution and 8-channel requirement if channel count is fixed.
