Demonstration circuit 2350B features the LTC6813-1, 18-channel battery-stack monitor. Multiple boards can be linked through a 2-wire isolated serial interface (isoSPI™) to monitor a long series of cells in a stack. The DC2350B demo board also features reversible isoSPI enabling a redundant communication path. The PCB, components, and DuraClik connectors are optimized for low EMI susceptibility and emissions. The DC2350B can communicate to a PC by connecting a DC2792B dual master isoSPI together with DC2026C Linduino® One. The DC2026 must be loaded with the appropriate program (called a sketch) to control the battery-stack monitor IC and receive data through a USB serial port. The DC2026 provides a standard SPI interface which can be translated to isoSPI and then connected to a DC2350B isoSPI port (J4 or J5 connector). The DC2792B companion board provides two SPI-isoSPI channels for reversible operation.

The LTC2873 is a robust pin-configurable multiprotocol transceiver that supports RS232, RS485, and RS422 protocols while operating on a single 3V to 5.5V supply. The LTC2873 can be configured as a half-duplex RS485 transceiver or as an RS232 transceiver using the same two bus pins.A pin-controlled integrated termination resistor allows for easy interface reconfiguration, eliminating external resistors and control relays. Loopback mode steers the driver inputs to the receiver outputs for diagnostic self-test. The RS485 receiver supports up to 256 nodes per bus, and features full failsafe operation for floating, shorted or terminated inputs.An integrated DC/DC boost converter uses a tiny 2mm ? 1.6mm inductor and one capacitor, eliminating the need for multiple supplies when driving RS232 levels.Applications Software Selectable RS232/RS485/RS422 Interface Industrial Sensors and Actuators Alarm Systems Traffic Control and Monitoring Highway Signs and Jumbo Displays

Demonstration circuit 2365A highlights the LTC2358 family of buffered input ADCs. The LTC2358/LTC2357/LTC2353/LTC2333 are low noise, high speed, 16-/18- bit successive approximation register (SAR) ADCs with integrated front end buffers. These ADCs accept a wide common mode range. Pico-amp inputs and high CMRR enable these ADCs to connect directly to a wide range of sensors without compromising measurement accuracy. The following text refers to the LTC2358-18 but applies to all parts in the family, the only differences being the number of bits, number of channels and the maximum sample rate. The LTC2358-18 has a flexible SoftSpan™ interface that allows conversion-by-conversion control of the input voltage span on a per-channel basis. An internal 2.048V reference and 2X buffer simplify basic operation while an external reference can be used to increase the input range and the SNR of the ADC.
