Product Information
Product Overview
LTC1380 is a CMOS analog multiplexer with SMBus® compatible digital interfaces. It is a single-ended 8-channel multiplexer. The SMBus digital interface requires only two wires (SCL and SDA). It has four hard-wired SMBus addresses, selectable with two external address pins. This allows four devices, each with a unique SMBus address, to coexist on one system and for four devices to be synchronized with one stop bit. The supply current is typically 10µA. Both digital interface pins are SMBus compatible over the full operating supply voltage range. This device's analog switches feature a typical RON of 35 ohm (±5V supplies), typical switch leakage of 20pA and guaranteed break-before-make operation. Charge injection is ±1pC typical. It is widely used in application such as data acquisition systems, process control, laptop computers, signal multiplexing/demultiplexing, analog-to-digital conversion systems etc.
