The LTC2107 is a 16-bit, 210Msps high performance ADC. The combination of high sample rate, low noise and high linearity enable a new generation of digital radio designs. The direct sampling front-end is designed specifically for the most demanding receiver applications such as software defined radio and multi-channel GSM base stations. The AC performance includes, SNR = 80dBFS, SFDR = 98dBFS. Aperture jitter = 45fsRMS allows direct sampling of IF frequencies up to 500MHz with excellent performance.Features such as internal dither, a PGA front-end and digital output randomization help maximize performance. Modes of operation can be controlled through a 3-wire serial interface (SPI).The double data rate (DDR) low voltage differential (LVDS) digital outputs help reduce digital line count and enable space saving designs.Applications Software Defined Radios Military Radio and RADAR Cellular Base Stations Spectral Analysis Imaging Systems ATE and Instrumentation

Demonstration circuit 2190A is a high output voltage, high efficiency synchronous PolyPhase® buck converter featuring the LTC3892EFE-1. This demo circuit is available in two versions. The input voltage range of both versions is from 16V to 55V. The DC2190A-A is configured using two each LTC3892EFE-1 devices with 4-phase interleaving operation which provides a 12V/60A output, while the DC2190A-B is configured using one LTC3892EFE-1 device with 2-phase interleaving operation which provides a 12V/30A output.

Demonstration circuit of DC2194A features the LTM4642IY, the wide input voltage, high efficiency and power density, dual 4A or single 8A DC/DC step-down μModule regulator. The step-down regulator operates from an input voltage range of 4.5V to 20V (or 2.5V min. with 5V external bias voltage at CPWR) and provides an adjustable output voltage range from 0.6V to 5V at 4A load current per channel. The part is capable of operating in dual phase single output, delivers up to 8A load current with interleaved two phases at 180 degrees. Differential output voltage sensing is available on Channel 1 for applications requiring more accurate output load regulation. A user-selectable mode input is provided to allow users to trade off ripple noise for light load efficiency: Discontinuous Mode (DCM) of operation delivers higher efficiency at light load while Continuous Conduction Mode (CCM) is preferred for noise sensitive applications.

Demonstration circuit DC1259A is a single-battery battery- backup controller featuring the LTC4110. The LTC4110 controller provides all the features and functions to offer a complete standalone battery-backup system. The LTC4110 is a multi-chemistry flyback battery charger and discharger that is scalable with other LTC4110s to allow a larger battery array for increased capacity and/or redundancy. The demo board requires a 12V input voltage and is initially configured to charge a 3 Li-Ion Smart Battery at 1A; the charge voltage is 12.6V. However, the Demo board can be easily configured for a standard battery as well. A SMBus interface is offered to allow host communications in control and status and/or support Smart Batteries. However, no host is required to use the LTC4110.

Demonstration circuit 1261A features the LTM8022 step-down μModule® regulator delivering a 3.3V/1A output from a 4.5V to 36V input supply. As a step-down converter, the LTM8022 requires a minimum amount of headroom to keep the output in regulation. Current sharing with another LTM8022 is enabled by tying the VIN, VOUT and SHARE pins together to support higher output loads.

Demo circuit DC1274A features the LTM8040 36V, 1A step-down constant current μModule® LED driver. The demonstration circuit is designed to drive a single LED or string of LEDs at up to 1A from a wide input voltage range of 4V to 36V. The maximum LED string voltage is 13V and the minimum voltage varies depending upon the BIAS pin supply arrangement.

Demonstration Circuit 1279 is a full-featured, multitopology LED driver with 1.5A switch current featuring the LT3518. The board is optimized to drive a 330mA LED string with a total LED voltage between the input voltage and 40V in a boost topology. The input voltage range (VIN) is 3V to 30V, and the supply pin that powers the switcher (PVIN) has an input voltage range of 3V to 40V.

The LTC2209 is a 160Msps 16-bit A/D converter designed for digitizing high frequency, wide dynamic range signals with input frequencies up to 700MHz. The input range of the ADC can be optimized with the PGA front end.The LTC2209 is perfect for demanding communications applications, with AC performance that includes 77.3dBFS Noise Floor and 100dB spurious free dynamic range (SFDR). Ultra low jitter of 70fsRMS allows undersampling of high input frequencies with excellent noise performance. Maximum DC specs include ?5.5LSB INL, ?1LSB DNL (no missing codes).The digital output can be either differential LVDS or single-ended CMOS. There are two format options for the CMOS outputs: a single bus running at the full data rate or demultiplexed busses running at half data rate. A separate output power supply allows the CMOS output swing to range from 0.5V to 3.6V.The ENC+ and ENC? inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles.Applications Telecommunications Receivers Cellular Base Stations Spectrum Analysis Imaging Systems
