A power-amp designed for use in low voltage especially battery-operated applications such as AM-FM radios portable tape cassettes intercoms power invertors etc. For minimum parts count C1 & C2 can be omitted. With pins 1 & 8 open circuit the gain is internally set to 20d B. With a 10micro F capacitor between pins 1 & 8 the gain is increased to 200d B & the gain can be set to anything between these limits by placing a resistor in series with this capacitor. For example a 1k 2 resistor here sets the gain to 50d B. The capacitor on pin 7 sets the power supply rejection ratio from 6d B with no connection to 50d B at 1k Hz with 10micro F. The inputs are referenced to ground while the output is automatically biased to half the supply voltage. Specifications Maximum supply voltage 15 Vdc Quiescent current 4m A Output power with 8 Omega load 325m W 6V supply THD at 125m W with 8 Omega load 0.2 6V supply Bandwidth 300k Hz Input resistance 50k Omega ...

An LED driver that will sequentially light ten LEDs when a gradually increasing voltage is applied to pin 5 dot mode or in bar mode all LEDs indicating voltages below input are lit. In dot mode there is a slight overlap so that at no point are all LEDs extinguished. A brightness control will set LED current between 2m A & 30m A. The drivers are stackable & displays with 100 or more LEDs are possible. Supply voltage 3V to 18V. The driver that sets the indication points can be referenced to a wide range of voltages. The LM3914 is available with linear steps. ...

An independent precision voltage comparator designed specifically to operate from a single power supply over a wide range of voltages. Operation from split rails is possible & the low power supply current drain is independent of the magnitude of the power supply voltage. Unique to the LM393 is that the input common-mode voltage range

Includes:: ground even though operated from a single power supply voltage. Designed to directly interface with TTL & CMOS & when operated from a
- supply will directly interface with MOS logic. The device is similar to the 392 but offers much lower input offset voltage & draws only half the supply current.

Ideal for home networks 10 Mbps transfer rate Compatible with 10100 Networks A network hub is a junction box for network connections enabling several computers to be included in a network. The hub is equipped with 5 ports & operates at a 10 Mbps transfer rate which is amply sufficient for a small home network. The housing is provided with magnetic pads allowing the HUB to be conveniently attached to for example a metal PC cabinetdesk or cable duct. Suitable for 10100 Mbps networks but with limited transfer rate. ...
