LTC1380/LTC1393 Single-Ended 8-Channel/ Differential 4-Channel Analog Multiplexer with SMBus Interface
U FEATURES DESCRIPTION
■ Micropower Operation: Supply Current = 20µA Max The LTC®1380/LTC1393 are CMOS analog multiplexers with ■ 2-Wire SMBus Interface SMBus® compatible digital interfaces. The LTC1380 is a ■ Single 2.7V to ±5V Supply Operation single-ended 8-channel multiplexer, while the LTC1393 is a ■ Expandable to 32 Single or 16 Differential Channels differential 4-channel multiplexer. The SMBus digital inter- ■ Guaranteed Break-Before-Make face requires only two wires (SCL and SDA). Both the ■ Low RON: 35Ω Single Ended/70Ω Differential LTC1380 and the LTC1393 have four hard-wired SMBus ■ Low Charge Injection: 20pC Max addresses, selectable with two external address pins. This ■ Low Leakage: ±5nA Max allows four devices, each with a unique SMBus address, to ■ Available in 16-Lead SO and GN Packages coexist on one system and for four devices to be synchro- nized with one stop bit.
U
The supply current is typically 10µA. Both digital interface
APPLICATIONS
pins are SMBus compatible over the full operating supply ■ Data Acquisition Systems voltage range. The LTC1380 analog switches feature a ■ Process Control typical RON of 35Ω (±5V supplies), typical switch leakage of ■ Laptop Computers 20pA and guaranteed break-before-make operation. Charge ■ Signal Multiplexing/Demultiplexing injection is ±1pC typical. ■ Analog-to-Digital Conversion Systems The LTC1380/LTC1393 are available in 16-lead SO and GN packages. Operation is fully specified over the commercial and industrial temperature ranges. , LTC and LT are registered trademarks of Linear Technology Corporation.
