ADM705ARZ-REEL7

ADM705ARZ-REEL7 is a fixed-threshold voltage supervisor (reset generator) from Analog Devices. It monitors Vcc and asserts its reset output when the supply falls below the factory-set threshold, providing reliable POR/brown-out protection for microcontrollers and digital hosts.
Key points:
- Fixed-threshold variants (select the exact threshold from the ADM705 family); used to guarantee a proper reset window.
- Operating supply: roughly 2.7 to 5.5 V range.
- Reset output: active-low, CMOS/TTL-compatible, designed to drive MCU reset pins directly.
- Low quiescent current, suitable for power-sensitive designs.
- Package/shipping: arranged in an 8-pin small-outline package; REEL7 indicates shipment on a 7-inch reel for automated assembly.
Applications include MCU/FPGA reset generation, brown-out protection, and ensuring deterministic startup in embedded systems. Check the specific ADM705ARZ-REEL7 datasheet for the exact threshold, timing, and pinout details, since multiple fixed-threshold options exist.

Equivalent voltage-supressor/reset parts from other vendors include: TI TLV803/TLV803B, Maxim MAX809/MAX810, Microchip MCP1315/MCP1316, and On Semiconductor NCP-series voltage supervisors (various thresholds). Use exact reset threshold and output type per ADM705 specs; verify cross-reference on your distributor/tool.

Here are typical features for ADM705ARZ-REEL7 (Analog Devices precision reference family) in concise form:
- Fixed voltage reference for ADC/DAC front-ends
- Ultra-low quiescent current (micropower)
- Low-noise, low-drift performance
- Wide operating supply range with good line/load regulation
- Robust temperature stability (industrial range)
- 8-lead package (e.g., SOIC/MSOP family)
- Tape-and-reel packaging: REEL7
- Suitable for precision reference applications requiring stable voltage
- ESD and protection features as per standards
- Manufactured and tested by Analog Devices (high reliability)
Note: Exact output voltage, current capability, and electrical specs depend on the specific variant; consult the latest datasheet for precise numbers.

- Pin count: 8 pins (8-pin package, e.g., SOIC/MSOP variant).
- Function: ADM705ARZ is a microprocessor supervisory/reset device with watchdog. It monitors the supply (VDD) and asserts a reset output if the voltage falls below its threshold or if the watchdog timer expires, ensuring a known MCU start-up state. It may include a manual reset input and watchdog input/output depending on the exact variant.

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (and sensors). It is a leading global supplier in the analog semiconductor market.
