DESCRIPTION
Ultra-Tiny, 16-Bit
∑ ADC
with I2C Interface
The LTC2451 is an ultra-tiny, 16-bit, analog-to-digital
converter. The LTC2451 uses a single 2.7V to 5.5V sup-
ply, accepts a single-ended analog input voltage and
communicates through an I2C interface. The converter
is available in an 8-pin, 3mm × 2mm DFN or TSOT-23
package. It includes an integrated oscillator that does not
require any external components. It uses a delta-sigma
modulator as a converter core and provides single-cycle
settling time for multiplexed applications. The LTC2451
includes a proprietary input sampling scheme that re-
duces the average input sampling current several orders
of magnitude lower than conventional ∑ converters.
The LTC2451 is capable of up to 60 conversions per
second and, due to the very large oversampling ratio,
has extremely relaxed antialiasing requirements. In the
30Hz mode, the LTC2451 includes continuous internal
offset calibration algorithms which are transparent to the
user, ensuring accuracy over time and over the operating
temperature range. The converter has external REF+ and
REF– pins and the input voltage can range from VREF– to
VREF+. If VREF+ = VCC and VREF– = GND, the input voltage
can range from GND to VCC.
Following a single conversion, the LTC2451 can auto-
matically enter sleep mode and reduce its power to less
than 0.2A. If the user reads the ADC once per second,
the LTC2451 consumes an average of less than 50W
from a 2.7V supply.
