ADG731BCP 32-channel SPST analog multiplexer ic
The ADG731BCP is a high-performance, 32-channel single-pole/single-throw (SPST) analog multiplexer integrated circuit from Analog Devices, designed for precision signal routing in data acquisition and instrumentation systems. It features 32 independently addressable analog input channels that connect to a single common output, with channel selection controlled via a versatile serial peripheral interface (SPI) that operates at speeds up to 50 MHz, enabling rapid switching and simplified microcontroller interfacing. The device operates from a wide dual or single supply range (±5 V to ±15 V or 9 V to 30 V single supply) and provides excellent on-resistance (typically 100 Ω) and flatness across the signal range, ensuring minimal signal distortion.
Housed in a compact 48-lead LFCSP package, it offers low power consumption, high channel-to-channel isolation, and guaranteed break-before-make switching action to prevent signal shorting. The ADG731BCP is engineered for high reliability and precision, with robust ESD protection and operation over an industrial temperature range (-40°C to +85°C), making it ideal for demanding signal path management applications.
Alternative High-Channel Multiplexer IC Solutions
● Texas Instruments MUX506IPW: A 16-channel, single-ended analog multiplexer with SPI interface and wide ±5 V to ±20 V supply range, offering high channel count and integration in a smaller package for space-constrained designs.
● Maxim Integrated (now part of Analog Devices) MAX14752EUE+: A 16-channel, high-voltage analog multiplexer with serial control, designed for fault-protected, high-reliability applications in harsh industrial environments.
● Microchip Technology MCP23S17-E/SS: A 16-bit I/O expander with serial interface that, while not an analog multiplexer, provides high-density digital I/O expansion with SPI control, serving complementary functions in digital signal routing systems.
● NXP Semiconductors PCA9548APW: An 8-channel I2C-controlled analog switch/multiplexer designed for lower channel count applications requiring I2C bus management and signal routing in mixed-signal systems.
