Introduction
ADG731BSUZ - Single-Pole Eight-Throw (SP8T) Analog Switch
Product Overview
The ADG731BSUZ is a high-performance, single-pole, eight-throw (SP8T) analog switch manufactured by Analog Devices (ADI). This low-voltage, low-on-resistance (Rₒₙ) component is designed for precision signal routing in space-constrained electronic systems.
Key Features
SP8T Analog/Digital Signal Routing
- Switch Topology: Single-pole, eight-throw (SP8T) configuration connects one common terminal to any of eight independent channels
- Signal Compatibility: Handles both analog and digital signals with bidirectional flow capability
Performance Characteristics
- Ultra-Low On-Resistance: 0.8 Ω typical (1.5 Ω max) at 3.3V supply minimizes signal attenuation
- Flat Resistance Profile: Stable Rₒₙ across entire signal range prevents distortion
- Wide Voltage Range: Operates from 1.8V to 5.5V with signal handling from -0.3V to VDD+0.3V
- Low Power Consumption: Typical quiescent current of 0.1 µA at 3.3V
Control & Protection
- Serial Control Interface: 3-bit select input (S0-S2) with chip enable (EN) pin
- Built-In Protection: ±2kV ESD protection and break-before-make switching
Primary Applications
- Data Acquisition Systems (sensor multiplexing, ADC/DAC routing)
- Test & Measurement Equipment (oscilloscopes, signal generators)
- Industrial Automation (PLC I/O expansion, process control)
- Medical Electronics (patient monitoring, diagnostic equipment)
- Consumer Electronics & IoT (audio switching, multi-sensor modules)
- Automotive Electronics (in-vehicle sensor networks, infotainment)
