The LTC2380-24 is a low noise, low power, high speed 24-bit successive approximation register (SAR) ADC with an integrated digital averaging filter. Operating from a 2.5V supply, the LTC2380-24 has a ?VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2380- 24 consumes only 28mW and achieves ?3.5ppm INL maximum and no missing codes at 24 bits.The LTC2380-24 has an easy to use integrated digital averaging filter that can average 1 to 65536 conversion results real-time, dramatically improving dynamic range from 101dB at 1.5Msps to 145dB at 30.5sps. No separate programming interface or configuration register is required.The high speed SPI-compatible serial interface supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisychain mode. The LTC2380-24 automatically powers down between conversions, reducing power dissipation at lower sampling rates.Applications Seismology Energy Exploration Medical Imaging High Speed Data Acquisition Industrial Process Control ATE

The LTC2983 measures a wide variety of temperature sensors and digitally outputs the result, in ?C or ?F, with 0.1?C accuracy and 0.001?C resolution. The LTC2983 can measure the temperature of virtually all standard (type B, E, J, K, N, S, R, T) or custom thermocouples, automatically compensate for cold junction temperatures and linearize the results. The device can also measure temperature with standard 2-, 3- or 4-wire RTDs, thermistors and diodes. It has 20 reconfigurable analog inputs enabling many sensor connections and configuration options. The LTC2983 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor.The LTC2983 allows direct interfacing to ground referenced sensors without the need for level shifters, negative supply voltages, or external amplifiers. All signals are buffered and simultaneously digitized with three high accuracy, 24-bit ?? ADCs, driven by an internal 10ppm/?C (maximum) reference.Applications Direct Thermocouple Measurements Direct RTD Measurements Direct Thermistor Measurements Custom Sensor Applications

The LT3753 is a current mode PWM controller optimized for an active clamp forward converter topology, allowing up to 100V input operation.A programmable volt-second clamp allows primary switch duty cycles above 50% for high switch, transformer and rectifier utilization. Active clamp control reduces switch voltage stress and increases efficiency. A synchronous output is available for controlling secondary side synchronous rectification.The LT3753 is available in a 38-lead plastic TSSOP package with missing pins for high voltage spacings.Applications Industrial, Automotive and Military Systems 48V Telecommunication Isolated Power Supplies

The LTM4651 is an ultralow noise, 58V, 24W DC/DC ?Module? inverting topology regulator. It regulates a negative output voltage (VOUT?) from a positive input supply voltage (VIN), and is designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components.Included in the package are the switching controller, power MOSFETs, inductor, filters and support components. The LTM4651 can regulate VOUT? to a value between ?0.5V and ?26.5V, provided that its input and output voltages adhere to the safe operating area criteria of the LTM4651: VIN + |VOUT?| ? 58V. A switching frequency range of 250kHz to 3MHz is supported (400kHz default) and the module can synchronize to an external clock.Despite being an inverting topology regulator, no level shift circuitry is needed to interface to the LTM4651?s RUN, PGOOD or CLKIN pins; those pins are referenced to GND.The LTM4651 is offered in a 15mm ? 9mm ? 5.01mm BGA package with SnPb or RoHS compliant terminal finish.Applications Avionics, Industrial Control and Test Equipment Video, Imaging and Instrumentation 48V Telecom and Network Power Supplies RF Systems
