The LTM2895 is a high speed isolated μModule®(micromodule) SPI interface with DAC control signals designed to isolate LTC’s family of general purpose DACs and to isolate general purpose SPI interfaces. The LTM2895 works with DACs and general purpose devices that have a mode (0, 0) SPI interface.The interface enables fast data throughput, which makes the LTM2895 ideally suited for a wide variety of applications. The high speed SPI-compatible serial port supports 1.71V to 5.5V logic supplies. The LTM2895 is targeted at generic SPI and digital-to-analog converter applications.The isolation barrier tolerates large voltage ground variations between the logic interface and the isolated side of the LTM2895. Uninterrupted communication is maintained during voltage transients greater than 50kV/μs.ApplicationsRemote Interface ControlIndustrial Process Control and AutomationTest and Measurement EquipmentBreaking Ground Loops

The LTM2985 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 LTM2985 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. The LTM2985 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor.The LTM2985 is an isolated 10-channel temperature mea-surement system software compatible with the LTC2986-1. It provides 5kV isolated power and SPI interface to the precision temperature-to-bits converter. The LTM2985 also includes a user-programmable EEPROM for custom sensor data.APPLICATIONSDirect Thermocouple MeasurementsDirect RTD MeasurementsDirect Thermistor MeasurementsCustom Sensor Applications

The LTM4600HV is a complete 10A, DC/DC step down power supply with up to 28V input operation. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over an input voltage range of 4.5V to 28V, the LTM4600HV supports an output voltage range of 0.6V to 5V, set by a single resistor. This high efficiency design delivers 10A continuous current (12A peak), needing no heat sinks or airflow to meet power specifications. Only bulk input and output capacitors are needed to finish the design.The low profile package (2.82mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. High switching frequency and an adaptive on-time current mode architecture enables a very fast transient response to line and load changes without sacrificing stability. Fault protection features include integrated overvoltage and short circuit protection with a defeatable shutdown timer. A built-in soft-start timer is adjustable with a small capacitor.The LTM4600HV is packaged in a compact (15mm × 15mm) and low profile (2.82mm) over-molded Land Grid Array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM4600HV is RoHS compliant.ApplicationsTelecom and Networking EquipmentMilitary and Avionics SystemsIndustrial EquipmentPoint of Load RegulationServers
