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

This reference design: featuring the TLV320AIC3256 audio codec: is a fully-functional USB powered streaming audio platform that allows external audio sources to be connected to the USB port of a PC or laptop. User control is provided via a powerful: easy-to-use Windows-based GUI.Software development for the TLV320AIC3256 is supported through TI's comprehensive PurePath™ Studio Development Environment. A powerful: easy-to-use tool designed specifically to simplify software development on the TLV320AIC3xxx miniDSP audio platform. The Graphical Development Environment consists of a library of common audio functions that can be dragged-and-dropped into an audio signal flow and graphically connected together. The DSP code can then be assembled from the graphical signal flow with the click of a mouse.The USB Audio Reference Design is operational with one USB cable connection to a PC. The USB connection provides power: control: and streaming audio data to the EVM for reduced setup and configuration.

GC5016 AGC Circuit Functional Description and Application Note

This TI Reference Design demonstrates a single op amp used as a slew rate limiter. In control systems for valves or motors: abrupt changes in voltages or currents can cause mechanical damages. By controlling the slew rate of the command voltages: into the drive circuits: the load voltages can ramp up and down at a safe rate.

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).

Demonstration circuit 1447A is an adjustable 200mA linear regulator featuring LT3082. Architected as a precision current source and voltage follower, it allows this new regulator to be used in many applications with adjustability to zero output. The LT3082 has an input range of 1.2V to 40V, but the demo board limits this range to 2.8V to 35V. The LT3082 withstands reverse input voltages and reverse output-to-input voltages without reverse-current flow.
