Voltage reference operates with less than 1µA
Linear Technology has announced a precision SOT23 voltage reference that operates on only 850nA of supply current.
According to Linear, the LT6656 has an initial error of less than 0.05% and a guaranteed temperature drift of less than 10ppm/ºC. It has an output drive capability of 5mA and has been designed for applications such as portable, wireless and remote devices.
The precision voltage reference device has been optimised for battery powered operation and is said to withstand reverse battery conditions, accept input voltages up to 18V and operate from voltages as low as 3mV above the output voltage.
The LT6656 is specified for operation from -40 to 85ºC, and is guaranteed functional over the extreme temperature range of -55 to 125ºC.
Brendan Whelan, design manager for Linear, said: "The high precision of the LT6656, combined with only 1µA of supply current packaged in a tiny SOT23, demonstrates a significant advance in voltage reference technology,"
The device is currently in production with seven voltage options.
