ON Semiconductor Moves to New Level of Precision Analog with Ultra-Low-Power, High-Accuracy Analog Voltage Reference ICs
CAT8900 devices offer accuracy as high as 0.02 percent with low, 800 nA maximum supply current for precision performance in test equipment and portable systems
The CAT8900 ICs provide a highly accurate voltage reference, with initial accuracy as high as 0.02 percent [± 0.5 millivolts (mV)] and a stable, 20 parts per million per degrees Celsius (ppm/ºC) temperature coefficient, while maintaining a low maximum supply current consumption of 800 nanoamperes (nA). The low current consumption allows the CAT8900 voltage references to remain powered on continuously, with minimal battery load. The low power consumption, combined with the very high initial accuracy and temperature stability of the devices, makes them ideal replacements for power-hungry, higher cost bandgap references in a wide range of portable applications. These include handheld medical devices, high resolution A/D (analog-to-digital) and D/A (digital-to-analog) converters, and precision regulator systems. The CAT8900 family offers nine voltage reference choices: 1.024 volts (V), 1.200 V, 1.250 V, 1.800 V, 2.048 V, 2.500 V, 2.600 V, 3.000 V and 3.300 V. Custom voltages are available on request. Each reference is available in four accuracy grades: ±0.5 mV, ±1.0 mV, ±2.5 mV and ±5.0 mV. The devices source or sink up to 10 milliamps (mA) of load current with as little as 50 mV of dropout. In most applications they do not require an output bypass capacitor.
