AMC7834 12-Bit Integrated Power-Amplifier Analog Monitor and Control (AMC) System Evaluation Module

DEM-SOT23LDO Compatible With Most Positive-Output LDO Regulators in 5- or 6-Lead SOT23 (DBV) Package

Demonstration Circuit 658 is a complete power management system using the LTC3456 for portable applications powered by a wall adapter, a USB port or a 2-cell alkaline battery, in that order of priority. DC658 provides three outputs: a 1.8V, 200mA core supply, a 3.3V, 150mA main supply, and a 3.3V, 50mA Hot Swap supply. All outputs are discharged to ground during shutdown. The synchronous buck (1.8V output) and the second converter (which operates as a buck or a boost depending on the power source, and provides 3.3V @ 150mA and 3.3V @ 50mA outputs) accept a 2V to 3.2V battery input or USB/Wall adapter input.

The LTC3882 is a dual, PolyPhase DC/DC synchronous step-down switching regulator controller with PMBus compliant serial interface. It uses a constant frequency, leading-edge modulation, voltage mode architecture for excellent transient response and output regulation. Each PWM channel can produce output voltages from 0.5V to 5.25V using a wide range of 3.3V compatible power stages, including power blocks, DrMOS or discrete FET drivers. Up to four LTC3882s can operate in parallel for 2-, 3-, 4-, 6- or 8-phase operation.LTC3882 system configuration and monitoring is supported by the LTpowerPlay? software tool. The device?s serial interface can be used to read back input voltage, output voltage and current, temperature and fault status. A wide range of operating parameters can be set via the digital interface or stored in internal EEPROM for use at power up. Switching frequency and phase, output voltage and device address can also be programmed using external configuration resistors.

The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltagecomparators fabricated on the Analog Devices, Inc. proprietaryXFCB3 Silicon Germanium (SiGe) bipolar process. TheADCMP580 features CML output drivers, the ADCMP581features reduced swing ECL (negative ECL) output drivers, andthe ADCMP582 features reduced swing PECL (positive ECL)output drivers.All three comparators offer 180 ps propagation delay and 100 psminimum pulse width for 10 Gbps operation with 200 fs randomjitter (RJ). Overdrive and slew rate dispersion are typically lessthan 15 ps.The ?5 V power supplies enable a wide ?2 V to +3 V inputrange with logic levels referenced to the CML/NECL/PECLoutputs. The inputs have 50 ? on-chip termination resistorswith the optional capability to be left open (on an individualpin basis) for applications requiring high impedance input. The CML output stage is designed to directly drive 400 mV into50 ? transmission lines terminated to ground. The NECL outputstages are designed to directly drive 400 mV into 50 ? terminatedto ?2 V. The PECL output stages are designed to directly drive400 mV into 50 ? terminated to VCCO ? 2 V. High speed latchand programmable hysteresis are also provided. The differentiallatch input controls are also 50 ? terminated to an independentVTT pin to interface to either CML or ECL or to PECL logic.The ADCMP580/ADCMP581/ADCMP582 are available in a16-lead LFCSP.Applications Automatic test equipment (ATE) High speed instrumentation Pulse spectroscopy Medical imaging and diagnostics High speed line receivers Threshold detection Peak and zero-crossing detectors High speed trigger circuitry Clock and data signal restoration
