Industry's Lowest Noise 2.5V Voltage Reference Features 2ppm/ºC Max Drift
Linear Technology has announced the LTC6655, an ultra-stable voltage reference with an unequaled noise level of only 625nVp-p (0.25ppmp-p) from 0.1Hz to 10Hz. 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 -40ºC to 125ºC supports automotive and industrial applications. Advanced curvature compensation allows this bandgap reference to achieve a drift of less than 2ppm/ºC and an output voltage accurate to ±0.025%, 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 wide range of line and load conditions. A shutdown mode is provided for low power applications. The noise characteristics and precision of the LTC6655 are truly groundbreaking, says Brendan Whelan, Design Manager for Linear Technology. This reference offers the best performance available for next generation instruments.
