The LTC2377-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2377-16 has a ?VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2377-16 consumes only 6.8mW and achieves ?0.5LSB INL maximum, no missing codes at 16 bits with 97dB SNR.The LTC2377-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 500ksps throughput with no cycle latency makes the LTC2377-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2377-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.The LTC2377-16 features a unique digital gain compression (DGC) function, which eliminates the driver amplifier?s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 ? VREF and full-scale code from VREF to 0.9 ? VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides adequate headroom for powering the driving amplifier from a single 5.5V supply.Applications Medical Imaging High Speed Data Acquisition Portable or Compact Instrumentation Industrial Process Control Low Power Battery-Operated Instrumentation ATE

The LT3797 is a triple output DC/DC controller designed to drive three strings of LEDs. The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages. The LT3797 includes an integrated DC/DC converter to produce a regulated 7.5V supply for the N-channel MOSFET gate drivers of the three channels. This high efficiency converter enables the part to operate from a wide input voltage range from 2.5V to 40V. The LT3797 is designed so that each converter can use the most suitable configuration to drive its LED load, whether step-up, step-down or a combination. Two key features enable this flexibility: first the LT3797 can sense output current at the high side of the LED string; and second, the voltage feedback pin, FBH, is referred to the ISP current sensing input. The CTRL inputs provide output current analog dimming capability. The TG drivers level shift the PWM signals to drive the gates of external LED-disconnect P-channel MOSFETs, allowing high PWM dimming range, and providing LED overcurrent protection and short-circuit protected boost capability.Applications Automotive and Industrial Lighting RGB Lighting Billboards and Large Displays

The LTC7106 is a precision, PMBus controlled, bidirectional current digital-to-analog converter that adjusts the output voltage of any conventional VFB referenced regulator. The LTC7106 can work with the vast majority of power management controllers or regulators to enable digital control of the output voltage. Internal power-on reset circuitry keeps the DAC output current at zero (high impedance IDAC) until a valid write takes place. Features include a range bit for easy interfacing to almost any impedance resistor divider, and an open-drain GPO output for controlling the Run or Enable pin of the DC/DC regulator. For most applications, the current DAC error is significantly attenuated with proper design. See more detail about VOUT accuracy in the Applications Information section of this data sheet. The LTC7106 is supported by the ADI LTpowerPlay? development tool with graphical user interface (GUI).Applications General Purpose Power Systems Telecom Systems Industrial Applications

The LTC4041 is a complete supercapacitor backup system for 2.9V to 5.5V supply rails. It contains a high current step-down DC/DC converter to charge a single supercapacitor or two supercapacitors in series. When input power is unavailable, the step-down regulator operates in reverse as a step-up regulator to backup the systemoutput from the supercapacitor(s).The LTC4041?s adjustable input current limit function reduces charge current to protect the input supply from overload while an external disconnect switch isolates theinput supply during backup. When the input supply drops below the adjustable PFI threshold, the 2.5A boost regulator delivers power from the supercapacitor to the systemoutput.An optional input overvoltage protection (OVP) circuit protects the LTC4041 from high voltage damage at the VIN pin. An internal supercapacitor balancing circuit maintainsequal voltages across each supercapacitor and limits the maximum voltage of each supercapacitor to a pre-determined value. The LTC4041 is available in a low profile (0.75mm) 24-Lead 4mm ? 5mm QFN package.ApplicationsRide-Through ?Dying Gasp?

The LTC5594 is a direct conversion quadrature demodulator optimized for high linearity zero-IF and low-IF receiver applications in the 300MHz to 9GHz frequency range. The very wide IF bandwidth of more than 1GHz makes the LTC5594 particularly suited for demodulation of very wideband signals, especially in 5G front-haul/back-haul receiver applications. The outstanding dynamic range of the LTC5594 makes the device suitable for demanding infrastructure direct conversion applications. Proprietary technology inside the LTC5594 provides the capability to optimize OIP2 to 65dBm, and achieve image rejection better than 60dB. The DC offset control function allows nulling of the DC offset at the A/D converter input, thereby optimizing the dynamic range of true zero-IF receivers that use DC-coupled IF signal paths. The wideband RF and LO input ports make it possible to cover all the major wireless infrastructure frequency bands using a single device. The IF outputs of the LTC5594 are designed to interface directly with most common A/D converter input interfaces. The high OIP3 and high conversion gain of the device eliminate the need for additional amplifiers in the IF signal path.APPLICATIONS 5G Base Station Front-haul/Back-haul Receivers Military and Satellite Receivers Point-to-Point Broadband Radios High Linearity Direct Conversion I/Q SDR Test Instrumentation DPD Receivers
