The LTC2051/LTC2052 are dual/quad zero-drift operational amplifiers available in the MS8 and SO-8/GN16 and S14 packages. For space limited applications, the LTC2051 is available in a 3mm ? 3mm ? 0.8mm dual fine pitch leadless package (DFN). They operate from a single 2.7V supply and support ?5V applications. The current consumption is 750?A per op amp.The LTC2051/LTC2052, despite their miniature size, feature uncompromising DC performance. The typical input offset voltage and offset drift are 0.5?V and 10nV/?C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB.The input common mode voltage ranges from the negative supply up to typically 1V from the positive supply. The LTC2051/LTC2052 also have an enhanced output stage capable of driving loads as low as 2k? to both supply rails. The open-loop gain is typically 140dB. The LTC2051/ LTC2052 also feature a 1.5?VP-P DC to 10Hz noise and a 3MHz gain-bandwidth product.Applications Thermocouple Amplifiers Electronic Scales Medical Instrumentation Strain Gauge Amplifiers High Resolution Data Acquisition DC Accurate RC Active Filters Low Side Current Sense

The LTC3722-1/LTC3722-2 phase-shift PWM controllers provide all of the control and protection functions necessary to implement a high efficiency, zero voltage switched (ZVS), full bridge power converter. Adaptive ZVS circuitry delays the turn-on signals for each MOSFET independent of internal and external component tolerances. Manual delay set mode enables secondary side control operation or direct control of switch turn-on delays. The LTC3722-1/LTC3722-2 feature adjustable synchronous rectifier timing for optimal efficiency. A UVLO program input provides accurate system turn-on and turn-off voltages. The LTC3722-1 features peak current mode control with programmable slope compensation and leading edge blanking, while the LTC3722-2 employs voltage mode control. The LTC3722-1/LTC3722-2 feature extremely low operating and start-up currents. Both devices include a full range of protection features and are available in the 24-pin surface mount GN package.Applications Telecommunications, Infrastructure Power Systems Distributed Power Architectures Server Power Supplies

The LT1339 is a high power synchronous current mode switching regulator controller. The IC drives dual N-channel MOSFETs to create a single IC solution for high power DC/DC converters in applications up to 60V.The LT1339 incorporates programmable average current limiting, allowing accurate limiting of DC load current independent of inductor ripple current. The IC also incorporates user-adjustable slope compensation for minimization of magnetics at duty cycles up to 90%.The LT1339 timing oscillator operating frequency is programmable and can be synchronized up to 150kHz. Minimum off-time operation provides main switch protection. The IC also incorporates a soft start feature that is gated by both shutdown and undervoltage lockout conditions.An output phase reversal pin allows flexibility in configuration of converter types, including inverting and negative topologies.Applications 48V Telecom Power Supplies Personal Computers and Peripherals Distributed Power Converters Industrial Control Systems Lead-Acid Battery Backup Systems Automotive and Heavy Equipment

Demonstration circuit 1780A-A features PolyPhase® design using the LTM4620EV, the high efficiency, high density, dual 13A, switch mode step-down power module regulator. The input voltage is from 4.5V to 16V. The output voltage is jumper selectable from 1.0V to 2.5V. DC1780A-A can deliver nominal 50A output current with 2× LTM4620s in parallel. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions.

The LTC2380/LTC2379/LTC2378/LTC2377/LTC2376 are low power, low noise ADCs with serial outputs that can operate from a single 2.5V supply. The demo manual refers to the LTC2379-18 but applies to all parts in the family, the only difference being the maximum sample rates and the number of bits. The LTC2379-18 supports a ±5V fully differential input range with a 101dB SNR, consumes only 18mW and achieves ±2LSB INL max with no missing codes at 18-bits. The DC1783A demonstrates the DC and AC performance of the LTC2379-18 in conjunction with the DC590 QuikEval™ and DC718 PScope™ data collection boards.
