Industry's Lowest Drift Bandgap Voltage Reference Features 1.5ppm/°C Max & 0.5ppmP-P of Noise
MILPITAS, CA - October 19, 2015 - 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.
Extremely Low Drift, Low Noise & Low Dropout

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
