Lowest drift claimed for bandgap voltage reference
The company claims this is the industry’s lowest drift bandgap voltage reference.
It outputs 2.5V from inputs between 50mV above the output, up to 40V, and with a supply current of 1.2mA. In shutdown mode, power consumption is reduced to 4-microamps. Load regulation error is less than 6ppm/mA and line regulation error is less than 4ppm/V, both under worst-case conditions. The LT6657 is fully specified for –40°C to 125°C and was designed for applications in instrumentation, test equipment and automotive systems. Additional voltage options are in development. Prices start at $3.19 each in 1,000-piece quantities.
