Demonstration Circuit 2048A is a nanopower buckboost DC/DC with energy harvesting battery life extender featuring the LTC3330. The LTC3330 integrates a high voltage energy harvesting power supply plus a DC/DC converter powered by a primary cell battery to create a single output supply for alternative energy applications. The energy harvesting power supply, consisting of an integrated low-loss full-wave bridge with a high voltage buck converter, harvests energy from piezoelectric, solar or magnetic sources. The primary cell input powers a buck-boost converter capable of operating down to 1.8V at its input. Either DC/DC converter can deliver energy to a single output.

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.

DC1851A: Demo Board for the LTC2872 RS232/RS485 Dual Multiprotocol Transceiver with Integrated Termination.

The LTC2380/LTC2379/LTC2378/LTC2377/LTC2376 are low power, low noise ADCs with serial outputs that can operate from a single 2.5V supply. The demo manual refers to the LTC2379-18 but applies to all parts in the family, the only difference being the maximum sample rates and the number of bits. The LTC2379-18 supports a ±5V fully differential input range with a 101dB SNR, consumes only 18mW and achieves ±2LSB INL max with no missing codes at 18-bits. The DC1783A demonstrates the DC and AC performance of the LTC2379-18 in conjunction with the DC590 QuikEval™ and DC718 PScope™ data collection boards.

DC1850A-B: Demo Board for the LTC4366-1/LTC4366-2 High Voltage Surge Stopper.

Demonstration circuit 2767A features the LTC6754 highspeed rail-to-rail comparator in a QFN package with LVDS compatible outputs. The DC2767 input is AC-coupled for single-ended signal greater than 5MHz and up to 445MHz. The DC2767 outputs are AC-coupled 50Ω source impedance for driving directly the 50Ω inputs of a 1GHz or higher oscilloscope. The DC2767 has a supply connection for the LTC6754 rail-to-rail inputs and a separate supply connection for the QFN LTC6754 LVDS outputs. The LTC6754 includes 4.5mV of hysteresis to minimize instability. For the QFN package, a separate pin is available to set the hysteresis from 0mV (off) up to 40mV. The QFN version also features output latching to provide the ability to capture the state of the comparator. The DC2767 provides a connection to set the hysteresis or for output latching. LTC6754 is ideally suited for high frequency line driver and clock recovery circuits.

The EVAL-AD8302-ARDZ shield illustrates the functionality of the AD8302, a gain and phase detector which operates from low frequency up to 2.7 GHz. The voltage outputs of the AD8302 are routed to the ANALOG IN connector of the Arduino base board. This allows the RF power detector’s output voltage to be easily digitized and processed by the Arduino base board’s integrated six-channel ADC.
