A low power quad version of the 741 op-amp featuring high gain & internal compensation with a total supply current requirement for the IC that is less than a single conventional 741. Each op-amp has a class AB output stage & so has virtually no crossover distortion. Additional features include a low input offset voltage 1m V low input offset current typically 4n A low input bias current typically 30n A & a unity gain bandwidth of 1 M Hz. Channel separation is 120d B with a maximum operating voltage of plusmn 18 Vdc. ...

A precision integrated circuit with an output voltage that is linearly proportional to the Centigrade temperature. The advantage over the LM335Z is that it is not necessary to subtract a large constant voltage from the output to obtain the Centigrade scale. The chip does not require any external calibration to achieve accuracies of plusmn 410 deg C at room temperature & plusmn 810deg C over full temperature range. The device draws only 56micro A from voltage supplies in the range 4V to 30V so it has very low self-heating lt 0.1deg C in still air. The LM35DZ oerates in the range 0 C to 100 C. Specifications Oerating range 0deg C to 100deg C plusmn 0.9deg C Non-linearity 0.2deg C Sensor slope 10m Vdeg C Load regulation 0.4m Vm A Line regulation 0.01m Vm A Quiescent current 56micro A at VS 5V56.2micro A at VS 30 V Temperature co-efficient ofquiescent current 0.39micro Adeg C Output impedance 0.1micro with 1m A load ...

An audio amp in a 14-pin DIL package that requires very few external components to make a complete 2.5W power amplifier. In most cases however it is advisable to add a Min Res 2.7 Omega & Polyester 0.1micro F in series from pin 8 to ground & an Axial 4.7micro F from pin 1 to ground. High-Output-Crystal-Cartridge Power Amp A 2.5W rms power amp the 380 is shown in the circuit driven by a high output crystal pickup. The IC requires only 4 other components without tone control only two other components simply omit C1 & RV1. ...

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.
