The LT6656 is a small precision voltage reference that draws less than 1μA of supply current and can operate with a supply voltage within 10mV of the output voltage.
The LT6656 offers an initial accuracy of 0.05% and temperature drift of 10ppm/°C.
Thanks to combined low power and precision characteristics LT6656 are ideal for portable and battery powered instrumentation.
The LT6656 can supply up to 5mA of output drive with 65ppm/mA of load regulation, allowing it to be used as the supply voltage and the reference input to a low power
ADC. The LT6656 can accept a supply voltage up to 18V and is available in few standard output voltages : 1.25V, 2.048V, 2.5V, 3V, 3.3V, 4.096V and 5V .
The LT6656 don’t need any configuration setting and require just two capacitors : one for the input , an one for the output .
Main features of the LT6656 precision voltage reference IC are :
low drift (A Grade: 10 ppm/°C Max, B Grade: 20 ppm/°C Max ) , high accuracy (A Grade: 0.05% Max , B Grade: 0.1% Max ) , ultralow supply current: 850nA , high output drive current: 5mA min , low dropout voltage: 10mV max ,fully specified from –40°C to 85°C ,operational from –55°C to 125°C ,wide supply range to 18V ,reverse input/output protection .
