This document introduces the general characteristics of the LME49725 dual high performance, high fidelity audio operational amplifier. The operational amplifier has extremely low distortion, noise and high slew rate, which can meet the most demanding audio application requirements.
The LM4860 is a bridge-connected audio power amplifier capable of delivering 1W of continuous average power to an 8Ω load with less than 1% THD+N over the audio spectrum from a 5V power supply.
The 'F240, 'F241, and 'F244 are octal buffers and line drivers designed to be employed as memory and address drivers, clock drivers, and bus-oriented transmitters/receivers, providing improved PC and board density.
The COP8SG Family ROM and OTP based microcontrollers are highly integrated COP8™ Feature core devices with 8k to 32k memory and advanced features including Analog comparators, and zero external components. These single- chip CMOS devices are suited for more complex applica- tions requiring a full featured controller with larger memory, low EMI, two comparators, and a full-duplex USART.
The LM3526 is a dual-port USB power switch and over-current protection, which is compatible with USB1.1 and USB 2.0 standards, and has 1ms fault flag delay, low RON and 500mA minimum continuous load current.
The LM5008 is a high voltage (100V) step-down switching regulator that features all of the functions needed to implement a low cost, efficient, Buck bias regulator. It is easy to implement and is provided in the MSOP-8 and the thermally enhanced LLP-8 packages. The regulator is based on a hysteretic control scheme using an ON time inversely proportional to VIN. This feature allows the operating frequency to remain relatively constant. The hysteretic control requires no loop compensation. An intelligent current limit is implemented with forced OFF time, which is inversely proportional to Vout. This scheme ensures short circuit protection while providing min- imum foldback. Other protection features include: Thermal Shutdown, VCC under-voltage lockout, Gate drive under-volt- age lockout, and Max Duty Cycle limiter.
The LM1881 Video sync separator extracts timing informa- tion including composite and vertical sync, burst/back porch timing, and odd/even field information from standard nega- tive going sync NTSC, PAL* and SECAM video signals with amplitude from 0.5V to 2V p-p. The integrated circuit is also capable of providing sync separation for non-standard, faster horizontal rate video signals. The vertical output is produced on the rising edge of the first serration in the vertical sync period. A default vertical output is produced after a time delay if the rising edge mentioned above does not occur within the externally set delay period, such as might be the case for a non-standard video signal.
LM45 is a precision temperature sensor produced by Texas Instruments. It is suitable for a temperature range of -20℃ to +100℃, with an accuracy of ±3℃. It is packaged in SOT-23
LM3433 is an adaptive constant on-time DC/DC buck constant current controller that provides a constant current for illuminating high power LEDs. The output configuration allows the anodes of multiple LEDs to be tied directly to the ground referenced chassis for maximum heat sink efficacy. The high frequency capable architecture allows the use of small external passive components and no output capacitor while maintaining low LED ripple current. Two control inputs are used to modulate LED brightness. An analog current control input is provided so the LM3433 can be adjusted to compensate for LED manufacturing variations and/or color temperature correction. The other input is a logic level PWM control of LED current. The PWM functions by shorting out the LED with a parallel switch allowing high PWM dimming frequencies. High frequency PWM dimming allows digital color temperature control, interference blanking, field sequential illumination, and brightness control. Additional features include thermal shutdown, VCC under-voltage lockout, and logic level shutdown mode. The LM3433 is available in a low profile LLP-24 package.
