概要
Description
ADR435BRMZ-R7 is Analog Devices’ fixed-output, precision voltage reference (ADR435 family). It provides a stable reference voltage for precision ADCs, DACs, and instrumentation, with low noise, low temperature drift, and good long-term stability. The “R7” suffix denotes the packaging/variant (tape-and-reel). It typically requires a single supply and proper decoupling, delivering a modest load current suitable for reference networks. Common use cases include data acquisition, DAC references, calibration sources, and precision instrumentation. For exact output voltage, initial accuracy, tempco, noise, load regulation, quiescent current, supply range, and pinout/package details, refer to the ADR435BRMZ-R7 datasheet.
Equivalent
ADR435BRMZ-R7 is a 2.5 V low-drift precision voltage reference (8-lead package). Direct 1:1 equivalents are limited; practical substitutes include other 2.5 V references with similar accuracy and tempco, such as TI REF5025/REF5020, Linear LT6650-2.5 or LT6655-2.5, and Analog Devices ADR4525/ADR4526/ADR4530 series. Always verify pinout, supply, noise, drift, and package when substituting.
