DS1099U-PR+

The DS1099U-PR+ is a low frequency dual EconOscillator in 8 pin µMAX package. It is a low cost, low power, low frequency silicon oscillator that generates two square wave outputs with frequency of 127.9Hz and 31.98Hz. Individual output enables allow both outputs to be enabled/disabled independently. Both outputs are capable of sinking 16mA allowing them to directly interface to light emitting diodes (LEDs) as well as other external circuitry. The DS1099 operates over a wide supply voltage making it suitable for both 3V and 5V systems.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 125°C
• No external timing components required
• Independent output enables (OE0, OE1)
• CMOS/TTL compatible outputs
• Relieves microprocessor of periodic interrupt
• Low power consumption
• Temp drift (max) is ±100ppm/°C
