Voltage reference supports automotive applications

Linear Technology has announced the LTC6655, an ultra-stable voltage reference with a noise level of 625nVp-p (0.25ppmp-p) from 0.1Hz to 10Hz for instrumentation and test equipment.

The company said the LTC6655 is an ideal companion to high-resolution DACs and ADCs required by instrumentation and test equipment, while the fully specified temperature range of -40C to 125C supports automotive and industrial applications.

Advanced curvature compensation allows this band-gap reference to achieve a drift of less than 2ppm/C and an output voltage accurate to +/-0.025 per cent, reducing or eliminating the need for system calibration.

The LTC6655 low dropout series references can be powered from as little as 500mV above the output voltage, up to a maximum supply voltage of 13.2V.

Superior load regulation of 3ppm/mA and +/-5mA source and sink capabilities coupled with only 5ppm/V line rejection give consistent performance over a range of line and load conditions.

A shutdown mode is provided for low-power applications.

The LTC6655 is currently in production with a 2.5V output version.

Additional voltage options will be available soon.

It is available in an MSOP-8 package.
