LM5104 High Voltage Half-Bridge Gate Driver with Adaptive Delay

LM20 is a precision analog output CMOS integrated circuit temperature sensor that operates over a −55˚C to +130˚C temperature range.

The LM2662/LM2663 CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.5V to 5.5V to the corresponding negative voltage. The LM2662/LM2663 uses two low cost capacitors to provide 200 mA of output current without the cost, size, and EMI related to inductor based converters. With an operating current of only 300 µA and operating efficiency greater than 90% at most loads, the LM2662/LM2663 provides ideal performance for battery powered systems. The LM2662/LM2663 may also be used as a positive voltage doubler. The oscillator frequency can be lowered by adding an external capacitor to the OSC pin. Also, the OSC pin may be used to drive the LM2662/LM2663 with an external clock. For LM2662, a frequency control (FC) pin selects the oscillator frequency of 20 kHz or 150 kHz. For LM2663, an external shutdown (SD) pin replaces the FC pin. The SD pin can be used to disable the device and reduce the quiescent current to 10 µA. The oscillator frequency for LM2663 is 150 kHz.

LMH0031 is a deserializer and decoder produced by Texas Instruments. It can decode SMPTE 292M, 259M, 344M and other standard video data, and convert them into 20-bit or 10-bit parallel data.

The LME49721 is a low distortion, low noise Rail-to-Rail Input/ Output operational amplifier optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49721 Rail-to-Rail Input/Output operational amplifier delivers superior signal amplification for outstanding performance. The LME49721 combines a very high slew rate with low THD+N to easily satisfy demanding applications. To ensure that the most challenging loads are driven without compromise, the LME49721 has a high slew rate of ±8.5V/μs and an output current capability of ±9.7mA. Further, dynamic range is maximized by an output stage that drives 10kΩ loads to within 10mV of either power supply voltage. The LME49721 has a wide supply range of 2.2V to 5.5V. Over this supply range the LME49721’s input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LME49721 is unity gain stable.
