Intersil Voltage Reference Sets Current Consumption Benchmark

Setting its mark as exhibiting the industry's lowest current usage, the ISL21009 voltage reference consumes 180 mA maximum over an operating temperature range from -40°C to +125°C with a temperature drift of 3 ppm/°C depending on the version. The device works with an input-voltage range up to 16.5V and delivers output voltages of 1.25V and 2.5V with a guaranteed initial accuracy as low as ±0.5 mV. Making it a viable candidate for control and data-acquisition applications, the reference specifies an output-voltage noise of 4 µVp-p from 0.1 Hz to 10 Hz. Other features include an output-current capability ±7 mA. The ISL21009 is available in three versions: B (3 ppm/°C), C (5 ppm/°C), and D (10 ppm/°C). Each version comes in an eight-lead SOIC package. Prices are $4.04 (B), $3.74 (C), and $2.65 (D) each/1,000. INTERSIL CORP., Milpitas, CA. (888) 352-6832.
