概述

Description

ADM705ARZ-REEL7 is an Analog Devices fixed-voltage reference (part of the ADM705 family). It provides a stable, low-noise reference voltage for precision analog circuits, ADCs/DACs, and calibration tasks. The ARZ suffix denotes the package variant, while REEL7 indicates tape-and-reel packaging for high-volume assembly. The exact output voltage and specs (tempco, quiescent current, line/load regulation) vary by variant; refer to the datasheet for the specific version you’re using.

Features

Key features of ADM705ARZ-REEL7 (typical for the ADM705 family):
- Microprocessor supervisor with reset output
- Wide supply range suitable for 1.8–5.5 V systems
- Fixed threshold variants (device variant determines threshold)
- Power-on reset with a defined reset window/delay
- Reset output: active-low logic level to the MCU
- Manual reset input for external forcing of reset
- Optional watchdog input to recover from software hangs
- Fast, reliable response to supply droop with glitch/immunity features
- Low quiescent current (high efficiency in idle systems)
- 8-pin package (SOP/PDIP family options) in tape-and-reel (REEL7) packaging
- RoHS-compliant
Note: Exact voltage thresholds and timing depend on the specific variant. See the datasheet for precise values.

Package

ADM705ARZ-REEL7 is in an 8‑lead SOIC (SOP‑8) package, supplied on a Tape & Reel (REEL7). ARZ denotes the package code for this 8‑pin SOIC.

Pinout

- Pin count: 8 pins (MSOP-8/SOIC-8 package).
- Function: Microprocessor reset supervisor/voltage detector. It monitors Vcc and asserts a reset output when the supply falls below its threshold; includes a manual reset input and an active-reset output (open-drain) for MCU reset during power-up/power-down.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits for various applications (signal processing, data conversion, power management, sensors, etc.).

Application

ADM705ARZ-REEL7 is a microprocessor supervisor/reset device (voltage monitor). Common applications:
- Microcontroller/FPGA/DSP reset generation with brown-out protection
- Power-on reset with deterministic timing
- Voltage monitoring for embedded and battery-powered systems
- Memory-safe-start and safe-reset circuits
- Industrial, automotive, telecom, and distributed-control systems needing reliable reset on supply fluctuations (often with low quiescent current)

Equivalent

Equivalent voltage supervisor/reset ICs (same role, similar thresholds): TI TLV803 (and TLV803-Q1), TI TPS3700; ON Semiconductor NCP301/NCP302; Maxim MAX809/MAX810; Microchip MCP131/MCP132; Analog Devices ADM706/ADM707. Be sure to match the same threshold (≈2.93 V or ≈4.63 V) and package type.
