LTC2460/LTC2462

Ultra-Tiny, 16-Bit ΔΣ ADCs

with 10ppm/°C Max

Precision Reference

DESCRIPTION

FEATURES

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 V_REFinput range and the LTC2462 is dif-

ferential with a V_REFinput 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. TheLTC2460/LTC2462includeaproprietary

input sampling scheme that reduces the average input

current several orders of magnitude when compared to

conventional delta sigma converters.

SPI Interface

Ultra-Tiny 12-Lead 3mm × 3mm DFN and MSOP

Packages

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.

APPLICATIONS

System Monitoring

Environmental Monitoring

Direct Temperature Measurements

The LTC2460/LTC2462 can sample at 60 conversions per

second, and due to the very large oversampling ratio,

have extremely relaxed antialiasing requirements. Both
