Analog Devices Inc.The LTC2975 is a 4-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. PMBus commands support power supply sequencing, precision point-of-load voltage adjustment and margining. DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include over and under current, voltage and temperature threshold limits for four power supply output channels as well as over and under voltage threshold limits for a single power supply input channel. Programmable fault responses can disable the power supplies with optional retry after a fault is detected. Faults that disable a power supply can automatically trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors four output voltages, four output currents, four external temperatures, input voltage and current, and die temperature. Input power, energy, and output power is also calculated. A programmable watchdog timer monitors microprocessor activity for a stalled condition and resets the microprocessor if necessary. A single wire bus synchronizes power supplies across multiple ADI Power System Management (PSM) devices. Configuration EEPROM with ECC supports autonomous operation without additional software.APPLICATIONS Computers and Network Servers Industrial Test and Measurement High Reliability Systems Video and Medical Imaging

Analog Devices Inc.The LTC1067/LTC1067-50 consist of two identical rail-to-rail, high accuracy and very wide dynamic range 2nd order switched-capacitor building blocks. Each building block, together with three to five resistors, provides 2nd order filter functions such as bandpass, highpass, lowpass, notch and allpass. High precision 4th order filters are easily designed. The center frequency of each 2nd order section is tuned by the external clock frequency. The internal clock-to-center frequency ratio (100:1 for the LTC1067 and 50:1 for the LTC1067-50) can be modified by the external resistors. These devices have a double sampled architecture which places aliasing and imaging components at twice the clock frequency. The LTC1067-50 is a low power device consuming about one half the current of the LTC1067. The LTC1067-50?s typical supply current is about 1mA from a 3.3V supply. The LTC1067 and LTC1067-50 are available in 16-pin narrow SSOP and SO packages. Mask programmable versions of the LTC1067 and LTC1067-50, with thin film resistors on-chip and custom clock-to-cutoff frequency ratios, can be designed in an SO-8 package to realize application specific monolithic filters.

LT3050EDDB Demo Board | Micropower Low Noise, Low Dropout Linear Regulator, Current Limit, Diagnostics, 2V ≤ VIN ≤ 45V, VOUT = 1.2V/1.5V/1.8V/2.5V/3.3V/5V/Adjustable at 100mA
Analog Devices Inc.Demonstration circuit 1515 is an adjustable 100mA linear regulator featuring the LT3050. The LT3050 is a micropower, low noise and low dropout voltage linear regulator. The device supplies 100mA of output current with a dropout voltage of 340mV. A 10nF bypass capacitor reduces output noise to 30μVRMS (10Hz to 100kHz bandwidth) and soft-starts the reference. The demo board's 2V to 45V input voltage range combined with its precision current limit and diagnostic functions make the IC an ideal choice for robust, high reliability applications such as protected antenna power supplies. The jumper-selectable output voltage can be set to 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V or a user-defined voltage. The input and output pins can withstand up to ±50V and the output is short-circuit protected.
The internal current limit should be considered when the input-to-output differential is high. The LT3050's current limit can be programmed by a single resistor and is accurate to ±5% over a wide input voltage and temperature range. A single resistor programs the LT3050’s minimum output current monitor, useful for detecting open-circuit conditions. The current monitor function sources a current equal to 1/100th of output current. A logic FAULT pin asserts low if the LT3050 is in current limit, operating below its minimum output current (open-circuit) or is in thermal shutdown.
