LT®6656 Precision Series

LT®6656 Precision Series

Linear Technology's LT6656 is a small precision voltage reference that draws less than 1 μA of supply current and can operate with a supply voltage within 10 mV of the output voltage. The LT6656 offers an initial accuracy of 0.05% and temperature drift of 10 ppm/°C. The combined low power and precision characteristics are ideal for portable and battery powered instrumentation.

The LT6656 can supply up to 5 mA of output drive with 65 ppm/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 18 V and withstand the reversal of the input connections.

The LT6656 output is stable with 1 μF or larger output capacitance and operates with a wide range of output capacitor ESR, ensuring that the LT6656 is simple to use.
