DESCRIPTION
Ultra-Tiny, 16-Bit I

C ΔΣ
ADCs with 10ppm/°C Max
Precision Reference
The LTC
®
2461/LTC2463 are ultra tiny, 16-Bit analog-to-
digital converters with an integrated precision reference.
They use a single 2.7V to 5.5V supply and communicate
through an I
2
C Interface. The LTC2461 is single-ended
with a 0V to 1.25V input range and the LTC2463 is dif-
ferential with a 1.25V input range. Both ADCs include a
1.25V integrated reference with 2ppm/°C drift perfor-
mance and 0.1% initial accuracy. The converters are
available in a 12-pin 3mm × 3mm DFN package or an
MSOP-12 package. They include an integrated oscillator
and perform conversions with no latency for multiplexed
applications. The LTC2461/LTC2463 include a proprietary
input sampling scheme that reduces the average input
current several orders of magnitude when compared to
conventional delta sigma converters.
Following a single conversion, the LTC2461/LTC2463
automatically power down the converter and can also be
configured to power down the reference. When both the
ADC and reference are powered down, the supply current
is reduced to 200nA.
The LTC2461/LTC2463 can sample at 60 conversions per
second and, due to the very large oversampling ratio,
have extremely relaxed antialiasing requirements. Both
include continuous internal offset and fullscale calibration
algorithms which are transparent to the user, ensuring ac-
curacy over time and the operating temperature range.
