Small precision voltage reference draws less than 1µA supply current

Milpitas, Calif.——Linear Technology has announced the LT6656, a precision SOT23 voltage reference that operates on only 850nA of supply current.

Aimed at portable, wireless and remote devices, the LT6656 has an initial error of less than 0.05% and a guaranteed temperature drift of less than 10ppm/°C. With an output drive capability of 5mA, the LT6656 is suitable for a wide range of applications. For example, the LT6656 could serve as both the supply voltage and the precision reference for a low power, high resolution ADC. The LT6656 can replace low power shunt references, offering better efficiency and regulation in the presence of variable load current and supply voltages. For many applications, the low quiescent current allows the LT6656 to remain in an always-on, stable state.

Building on Linear Technology's family of precision voltage references, the LT6656 is optimized for battery-powered operation. This bipolar device can withstand reverse battery conditions, accept input voltages up to 18V and operate from voltages as low as 3mV above the output voltage. When unpowered, the output is high impedance, avoiding loading on the rest of the circuit.

The LT6656 is fully specified for operation from -40°C to 85°C, and is guaranteed functional over the extreme temperature range of -55°C to 125°C.

Pricing: Starts at $1.74 each in 1,000-piece quantities.
Availability: In production with seven voltage options.
