AD5311RBRMZ-RL7

Digital To Analog Converters Overview

The AD5311RBRMZ-RL7 is a single-channel, 10-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC family by Analog Devices. It features an I2C serial interface and includes an enabled-by-default internal 2.5 V reference with a typical drift of 2 ppm/°C. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and supports selectable output spans of 0 V to VREF or 0 V to 2 × VREF. Key performance metrics include a maximum integral nonlinearity (INL) of ±0.5 LSB, a total unadjusted error (TUE) of 0.06% of full-scale range (FSR), and a low glitch impulse of 0.1 nV-sec. It provides high drive capability up to 20 mA and consumes only 1.2 mW at 3.3 V in normal mode.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RL7' against the manufacturer's official ordering guide to confirm reel packaging quantities and tape-and-reel specifications. Ensure the component matches the industrial temperature range of −40°C to +105°C required for the application environment. Cross-reference the datasheet revision to confirm current electrical parameters before finalizing procurement.

Digital To Analog Converters Selection Notes

Select the AD5311R variant specifically when an I2C interface is required, as opposed to the SPI-based AD5310R. Confirm that the system logic levels are compatible with the 1.62 V to 5.5 V VLOGIC input range. Verify that the required output drive current does not exceed the 20 mA short-circuit limit and that the capacitive load remains within stability limits (up to 10 nF with parallel resistance).

Digital To Analog Converters Part Context

This component belongs to the AD5310R/AD5311R nanoDAC family, which utilizes a segmented resistor string architecture guaranteed to be monotonic by design. The AD5311R is functionally similar to the AD5310R but differs in its communication protocol, utilizing I2C instead of SPI. These devices are designed for low-power applications requiring high relative accuracy and stable reference voltages without external components.

Digital To Analog Converters Replacement Considerations

Public documentation indicates pin-to-pin domestic alternatives exist for the AD5310 model series. However, specific verified substitute part numbers for the AD5311R variant are not provided in the available source material. Any replacement must match the I2C interface, 10-bit resolution, MSOP-10 package, and operating temperature range.
