APPLICATIONS INFORMATION
ADC REFERENCE
The LTC2364-18 requires an external reference to define
its input range. A low noise, low temperature drift refer-
ence 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 LTC6655-5 is particularly well suited for
use with the LTC2364-18. The LTC6655-5 offers 0.025%
(max) initial accuracy and 2ppm/°C (max) temperature
coefficient for high precision applications. The LTC6655-5
is fully specified over the H-grade temperature range and
complements the extended temperature operation of the
LTC2364-18 up to 125°C. We recommend bypassing the
LTC6655-5witha47Fceramiccapacitor(X5R,0805size)
close to the REF pin.
TheREFpinoftheLTC2364-18drawscharge(QCONV)from
the 47F bypass capacitor during each conversion cycle.
The reference replenishes this charge with a DC current,
IREF = QCONV/tCYC. The DC current draw of the REF pin,
IREF, depends on the sampling rate and output code. If
the LTC2364-18 is used to continuously sample a signal
at a constant rate, the LTC6655-5 will keep the deviation
of the reference voltage over the entire code span to less
than 0.5LSBs.
When idling, the REF pin on the LTC2364-18 draws only
a small leakage current (< 1A). In applications where a
burst of samples is taken after idling for long periods as
shown in Figure 6, IREF quickly goes from approximately
0A to a maximum of 0.2mA at 250ksps. This step in DC
current draw triggers a transient response in the reference
that must be considered since any deviation in the refer-
ence output voltage will affect the accuracy of the output
