The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors, and frequency modulation and sweeping can be accomplished with an external voltage. The 8038 is fabricated with advanced monolithic technology, using Schottky barrier diodes and thin film resistors, and the output is stable over a wide range of temperature and supply variations. These devices may be interfaced with phase locked loop circuitry to reduce temperature drift to less than 250ppm\/oC. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eFeatures:-\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• \u003c\/span\u003e\u003cspan\u003eLow Frequency Drift with Temperature 250ppm\/°C \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e • Low Distortion 1% (Sine Wave Output) \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• High Linearity  0.1% (Triangle Wave Output) \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Wide Frequency Range  0.001Hz to 300kHz \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Variable Duty Cycle  2% to 98% \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• High Level Outputs TTL to 28V \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Simultaneous Sine, Square, and Triangle Wave Outputs \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Easy to Use - Just a Handful of External Components Required \u003c\/span\u003e\u003c\/p\u003e","brand":"Indian Hobby Center","offers":[{"title":"Pack of 1","offer_id":40156252504107,"sku":"52504107","price":209.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/ic-6876667183147.jpg?v=1794545029"},{"product_id":"ne555-ne555l-timer-ic","title":"NE555 \/ LM555 Timer IC, DIP-8 (Pack of 1)","description":"\u003ch4 style=\"color:#0167A3;margin:0 0 6px\"\u003eKey specs\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Timer (astable \/ monostable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply:\u003c\/strong\u003e 4.5 V to 16 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e up to 200 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e DIP-8\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eSee the pinout photo for the pin numbers.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\n\u003cp\u003eTiming from microseconds to hours \u003cbr\u003eActable or nonstable operation \u003cbr\u003eAdjustable duty cyclist-compatible output can sink or source up to 200 ma \u003cbr\u003eTtl-compatible output can sink or source up to 200 ma\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003eThese devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of vcc. These levels can be altered by use of the control-voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset (reset) input can override all other inputs and can be used to initiate a new timing cycle. When reset goes low, the flip-flop is reset, and the output goes low. When the output is low, a low-impedance path is provided between discharge (disch) and ground. The output circuit is capable of sinking or sourcing current up to 200 ma. Operation is specified for supplies of 5 v to 15 v. With a 5-v supply, output levels are compatible with ttl inputs.\u003c\/p\u003e","brand":"Indian Hobby Center","offers":[{"title":"Pack of 1","offer_id":40156256370731,"sku":"56370731","price":12.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/ic-6876669116459.jpg?v=1794545029"},{"product_id":"um66-bt66t-bt66-melody-generator-ic","title":"UM66 Melody Generator IC, TO-92 (Pack of 1)","description":"\u003ch4 style=\"color:#0167A3;margin:0 0 6px\"\u003eKey specs\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Melody (tune) generator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply:\u003c\/strong\u003e 1.5 V to 4.5 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e TO-92 (3 pins)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eSee the pinout photo for the pin numbers.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\n\u003cp\u003ePlay a melody consisting of 64 Notes \u003cbr\u003eLower range of operating voltage form 0.3V to 3.5V \u003cbr\u003eTypical Operating Voltage: 3.3V \u003cbr\u003eCan easily drive a speaker through NPN Transistor\u003c\/p\u003e\n\u003cp\u003eUsed to play melody.
