DAC70508MRTET

Digital To Analog Converters Overview

The DAC70508MRTET is an octal true 14-bit digital-to-analog converter manufactured by Texas Instruments. It features a buffered voltage output architecture with an R-2R structure and SPI interface. The device operates on analog supply voltages from 2.7 V to 5.5 V and digital supplies from 1.7 V to 5.5 V. Key electrical parameters include a settling time of 5 µs, a sampling rate of 1 MS/s, and a typical operating current of 5 mA. Linearity specifications are defined by ±0.5 LSB for both differential and integral nonlinearity, with a gain error of 0.14% FSR. It is housed in a 16-WQFN package and supports an operating temperature range of -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'MRTET' against the manufacturer datasheet to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with RoHS3 standards if required by the target assembly process. Cross-reference the full part number to distinguish between reel and cut-tape variants offered by distributors.

Digital To Analog Converters Selection Notes

Select this component when eight independent channels are required within a single integrated circuit. The 14-bit resolution balances precision needs with power consumption constraints. Verify that the system requires buffered voltage outputs rather than current-mode signals. Confirm that the SPI interface timing aligns with the host microcontroller capabilities.
