Intersil Announces ISL60002 Precision Voltage References
Intersil Corp. (Milpitas, CA) announced new 1.25 V and 2.5 V additions to its expanding line of ultra-low-power precision voltage references. The ISL60002 voltage references bring the precision performance standards previously available only in laboratory equipment to portable and battery-operated systems.
The low, sub-1.5 µW power consumption of the ISL60002, 400 nA at 2.7 Vin, allows the voltage references to remain powered on continuously by the system battery. By operating the reference continuously biased, 12-bit to 24-bit battery-powered data acquisition circuits that normally disable the reference between conversions can now provide high accuracy and low long-term drift by eliminating the effects of initial accuracy changes and the time delay as the reference settles to its final value.
The ISL60002C-12 and ISL60002C-25 and the ISL60002D-12 and ISL60002D-25 in three-lead SOT23 packages are available off the shelf with 1,000-unit prices starting at $1.45 and $0.95, respectively. The ISL60002C-12 and ISL60002C-25 and the ISL60002D-12 and ISL60002D-25 in eight-lead SOICs are available off the shelf with 1,000-unit prices starting at $1.50 and $0.99, respectively.
