AD581LH AD581 Series Voltage Reference IC Through Hole ±0.05% 10mA TO-5-3

GENERAL DESCRIPTION

The AD581 is a 3-pin, temperature compensated, monolithic,band gap voltage reference that provides a precise 10.00 V outputfrom an unregulated input level ranging from 12 V to 30 V.Laser wafer trimming (LWT) is used to trim both the initialerror at +25°C as well as the temperature coefficient, resultingin high precision performance previously available only in expen-sive hybrids or oven regulated modules. The 5 mV initial errortolerance and 5 ppm/°C guaranteed temperature coefficient ofthe AD581L is available in a monolithic voltage reference.The band gap circuit design used in the AD581 offers severaladvantages over classical Zener breakdown diode techniques.Most important, no external components are required toachieve full accuracy and significant stability to low powersystems. In addition, total supply current to the device,including the output buffer amplifier (which can supply upto 10 mA) is typically 750 μA. The long-term stability of theband gap design is equivalent to selected Zener referencediodes.The AD581 is recommended for use as a reference for 8-, 10-or 12-bit digital-to-analog converters (DACs) that require anexternal precision reference. The device is also ideal for all typesof analog-to-digital converters (ADCs) up to 14-bit accuracy,either successive approximation or integrating designs, and cangenerally offer better performance than that provided by standardself-contained references

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen. 

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
