AD5449YRUZ-REEL7

Digital To Analog Converters Overview

The AD5449YRUZ-REEL7 is a dual-channel, 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates on a CMOS submicron process with a supply voltage range of 2.5 V to 5.5 V. The device features a 10 MHz multiplying bandwidth and supports an update rate of 2.47 MSPS. It utilizes a double-buffered 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Key performance metrics include a settling time of 80 ns (±1 mV), INL of ±1 LSB, and DNL of -1/+2 LSB. The component is housed in a 16-lead TSSOP package and functions within an extended temperature range of −40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details. The REEL7 suffix indicates tape-and-reel packaging. Confirm RoHS compliance status through official datasheets or certification documents prior to procurement.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 12-bit precision is required alongside high-speed updating capabilities up to 2.47 MSPS. Ensure the system design accommodates the 2.5 V to 5.5 V supply range and utilizes an external reference input within the ±10 V limit. Verify that the host microcontroller supports the required 3-wire serial protocol timing constraints.

Digital To Analog Converters Part Context

This part belongs to the AD5429/AD5439/AD5449 family of multiplying DACs. The AD5449 specifically provides 12-bit resolution, whereas the AD5429 offers 8 bits and the AD5439 offers 10 bits. All variants share identical pinouts, interfaces, and general electrical characteristics, differing primarily in resolution and associated linearity specifications.

Digital To Analog Converters Replacement Considerations

The AD5429YRUZ and AD5439YRUZ are direct pin-compatible substitutes within the same family, offering lower resolutions of 8-bit and 10-bit respectively. No other cross-model replacements are confirmed in the provided documentation.
