LTC2460/LTC2462
Ultra-Tiny, 16-Bit ΔΣ ADCs
with 10ppm/°C Max
Precision Reference
DESCRIPTION
The LTC®2460/LTC2462 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 SPI Interface. The LTC2460 is single-ended
with a 0V to VREF input range and the LTC2462 is dif-
ferential with a ±VREF input range. Both ADC’s include
a 1.25V integrated reference with 2ppm/°C drift per-
formance and 0.1% initial accuracy. The converters are
available in a 12-pin DFN 3mm × 3mm package or an
MSOP-12 package. They include an integrated oscillator
and perform conversions with no latency for multiplexed
applications. The LTC2460/LTC2462 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 LTC2460/LTC2462
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 LTC2460/LTC2462 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.
