The Texas Instruments bq27411-G1 reference design is an easy to configure fuel gauging solution for single series cell Li-Ion battery packs. The device requires minimal configuration and uses One Time Programmable (OTP) Non-Volatile Memory (NVM) to avoid an initialization download by the system processor.The bq27411-G1 uses the patented Impedance Track™ algorithm for fuel gauging: and provides information such as remaining battery capacity (mAh): state-of-charge (%): and battery voltage (mV).

One way to improve the performance of a graphics system is to place an advanced digital signal processor between the host processor and the video controller. This book the author's bachelor's thesis at MIT discusses the suitability of the TMS320C30 Digital Signal Processor to that task.The book begins with a listing of the factors that make the TMS320C30 the digital signal processor of choi

The LTC2372-18 is a low noise, high speed, 8-channel 18-bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2372-18 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges. The LTC2372-18 achieves ?2.75LSB INL (maximum) in all input ranges, no missing codes at 18-bits and 100dB (fully differential)/ 95dB (pseudo-differential) SNR (typical).The LTC2372-18 has an onboard low drift (20ppm/?C max) 2.048V temperature-compensated reference and a single-shot capable reference buffer. The LTC2372-18 also has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic through which a sequencer with a depth of 16 may be programmed. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2372-18 dissipates only 27mW and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. A sleep mode is also provided to reduce the power consumption of the LTC2372-18 to 300?W for further power savings during inactive periods.Applications Programmable Logic Controllers Industrial Process Control High Speed Data Acquisition Portable or Compact Instrumentation ATE

Demonstration circuit 2116A features the LTC4233/LTC4234 10A/20A Guaranteed SOA Hot Swap™ Controllers. The LTC4233 and LTC4234 are ideally suited for compact power distribution control in 2.9V to 15V applications for hot board insertion protection, high side power switching, and electronic circuit breaker functions.

The TVP5154 video decoder product includes the additional functionality of an integrated polymorphic down-scaler for both vertical and horizontal scaling. The video images can be downscaled in both horizontal and vertical directions to an arbitrary size. This Application Note outlines how to correctly use this scaler feature for standard NTSC and PAL video. Also included are the register settings

The ADL5920 is an ultrawideband, bidirectional detector that simultaneously measures forward and reverse rms power levels in a signal path, along with the return loss.The forward and reverse power traveling through the integrated bidirectional bridge is measured using two 50 dB linear in dB rms detectors. The detector output voltages, available at the VRMSF and VRMSR pins, are proportional to the forward and reflected power in dBm. A third, differential, output produces a voltage proportional to the return loss (reflection coefficient) in dB, closely related to the voltage standing wave ratio (VSWR). The common-mode level of this output is externally adjustable through the VOCM pin.The primary transmission line of the bidirectional bridge, from RFIN to RFOUT (or vice versa) is dc-coupled and allows small amounts of dc bias current through the bridge. When dc-coupled to source and load, the positive and negative supply pins of the ADL5920 must be connected to +5 V and ?2.5 V, respectively (relative to the dc voltage at RFIN and RFOUT). The internal detector circuitry is also dc-coupled to the directional bridge to support measurements down to 9 kHz.The maximum input signal on each of the RF ports (RFIN and RFOOUT) is 30 dBm for open and shorted terminations and 33 dBm for a matched termination.The ADL5920 draws 160 mA from a 5 V supply and has a low power, power-down mode controlled through the PWDN/TADJS pin.The device is supplied in a 32-lead, 5 mm ? 5 mm LFCSP and is specified for ambient operating temperatures in the ?40?C to +85?C range.Multifunction pin names may be referenced by their relevant function only.Applications Industrial metering Broadband inline power and return loss measurement Transmit power control and automatic level control in wireless transmitters, signal generators, network analyzers, and wireless communications testers Condition based monitoring of system modules, cables, and connectors

DC816A-G: Demo Board for the LTC2298 Dual 14-Bit, 65Msps Low Power 3V ADCs.

The optical module offers an effective high-speed solution for a growing telecom market. Data rates range from 155 Mbps to 6 Gbps and even up to 10 Gbps. Transmitter optical sub-assemblies (TOSAs) and laser drivers may have different resistances in a given application so the reflection could be worse if the designer does not use an impedance transfer circuit to absorb it. Additional uncertain noi
