ADC REFERENCE
The LTC2382-16 requires an external reference to define its
input range. A low noise, low temperature drift reference
is critical to achieving the full datasheet performance
of the ADC. Linear Technology offers a portfolio of high
performance references designed to meet the needs of
many applications. With its small size, low power and high
accuracy, the LTC6652-2.5 is particularly well suited for
use with the LTC2382-16. The LTC6652-2.5 offers 0.05%
(max) initial accuracy and 5ppm/°C (max) temperature
coefficient for high precision applications. The LTC6652-2.5
is fully specified over the H-grade temperature range and
complements the extended temperature operation of the
LTC2382-16 up to 125°C. We recommend bypassing the
LTC6652-2.5 with a 47μF ceramic capacitor (X5R, 0805
size) close to the REF pin. All performance curves shown
in this datasheet were obtained using the LTC6652-2.5.
