Industry’s Lowest Drift Bandgap Voltage Reference Features 1.5ppm/°C Max & 0.5ppmP-P of Noise

Linear Technology announces the LT6657, a family of ultra-stable bandgap voltage references that exhibits less than 1.5ppm/°C of temperature drift. Reinforcing this groundbreaking performance, the LT6657 has only 0.5ppmp-p of low frequency noise, less than 30ppm of long term drift and 35ppm of thermal hysteresis.

The LT6657 is fully specified for –40°C to 125°C and was designed for the most demanding high performance instrumentation, test equipment and automotive systems. The LT6657’s buffered output can source and sink up to 10mA. The LT6657 can operate on a supply voltage from as low as 50mV above the output, up to 40V, and with a supply current of only 1.2mA. In shutdown mode, power consumption is reduced to 4µA. Load regulation error is less than 6ppm/mA and line regulation error is less than 4ppm/V, both under worst case conditions.

“With its outstanding precision and noise, the LT6657 sets a new high water mark for bandgap references,” says Brendan Whelan, Design Manager for Linear Technology. “There is now a low dropout, small and adaptable voltage reference option with enough precision for the next generation of ultra-precision electronics.”

The LT6657 is currently in production with a 2.5V output version. Additional voltage options are in development. Prices start at $3.19 each in 1,000-piece quantities. For more information, visit www.linear.com/product/LT6657.
