DC1101A: Demo Board for LTC4097 USB/Wall Adapter Standalone Li-Ion/Polymer Battery Charger

The LTC2751 is a family of 12-, 14-, and 16-bit multiplying parallel-input, current-output DACs. They operate from a single 2.7V to 5.5V supply. All parts are guaranteed monotonic over temperature. The LTC2751A-16 provides 16-bit performance (?1LSB INL and DNL) overtemperature without any adjustments. These SoftSpan? DACs offer six output ranges ? two unipolar and four bipolar ? that can be programmed through the parallel interface, or pin strapped for operation in a single range.These parts use a bidirectional input/output parallel interface that allows read back of any on-chip register. A power-on circuit resets the DAC output to 0V when power is initially applied. A logic low on the CLR pin asynchronously clears the DAC to 0V in any output range. The parts are specified over commercial and industrial temperature ranges.Applications High Resolution Offset and Gain Adjustment Process Control and Industrial Automation Automatic Test Equipment Data Acquisition Systems

DC1171A-A: Demo Board for LTC3851 Synchronous Step-Down Switching Regulator Controller

Demonstration circuit DC1180 is a dual output regulator consisting of two identical constant frequency step-down converters, based on the LTC3407A monolithic dual synchronous buck regulator in the 3 × 3 DFN-10 package. The LTC3407A is similar to the LTC3407 but has a lower ripple Burst Mode operation and includes an optional external soft-start. The DC1180 has an input voltage range of 2.5V to 5.5V, and either output is capable of delivering up to 600mA of output current. In Burst Mode® operation, the DC supply current is typically only 25 µA (per channel) at no load, and less than 1 µA in shutdown. The DC1180 is a very efficient circuit: up to 96% for either circuit.
