LM339N LM339N
£0.76
Four independent precision voltage comparators with a typical input offset voltage of 2m V & designed to operate from a single power supply. The input common-mode voltage range

Includes:: ground even though operated from a single power supply voltage. Identical to the 3302 but offering enhanced supply voltage range & voltage gain typically 200. Designed to directly interface with TTL & CMOS & when used with a
- supply will directly interface with MOS logic where the low power drain of the LM339 is a distinct advantage over standard comparators.

LM348N Op-Amp LM348N
NSC
£1.00
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. ...

LM35 Precision
Centigrade Temperature
Sensor LM35DZ
£2.48
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 ...

LM380N LM380N
£1.73
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. ...

LM3914 Bargraph
Display LM3914N
£4.70
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. ...

LM393N LM393N
£0.76
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.

LM386N-1 LM386N-1

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 and C2 can be omitted. With pins 1 and 8 open circuit the gain is internally set to 20dB. With a 10microF capacitor between pins 1 and 8 the gain is increased to 200dB and the gain can be set to anything between these limits by placing a resistor in series with this capacitor. For example a 1k2 resistor here sets the gain to 50dB. The capacitor on pin 7 sets the power supply rejection ratio from 6dB with no connection to 50dB at 1kHz with 10microF. The inputs are referenced to ground while the output is automatically biased to half the supply voltage. SpecificationsMaximum supply voltage15VdcQuiescent
