Lowest drift claimed for bandgap voltage reference

New Products |
Linear Technology Corp. has introduced the LT6657, a family of bandgap voltage references that exhibits less than 1.5ppm/°C of temperature drift.

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.
