LTC2453

Ultra-Tiny, Differential,

16-Bit

ADC With

C Interface

DESCRIPTION

The LTC

2453 is an ultra-tiny, fully differential, 16-bit,

analog-to-digital converter. The LTC2453 uses a single

2.7V to 5.5V supply and communicates through an I

interface. The ADC is available in an 8-pin, 3mm

2mm DFN

package or 8-pin, 3mm

3mm TSOT package. It includes

an integrated oscillator that does not require any external

components. It uses a delta-sigma modulator as a converter

core and has no latency for multiplexed applications. The

LTC2453 includes a proprietary input sampling scheme

that reduces the average input sampling current several

orders of magnitude lower than conventional delta-sigma

converters. Additionally, due to its architecture, there is

negligible current leakage between the input pins.

The LTC2453 can sample at 60 conversions per second,

and due to the very large oversampling ratio, has ex-tremely

relaxed antialiasing requirements. The LTC2453 includes

continuous internal offset and full-scale calibration algo-

rithms 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 differen-

tial input voltage range can extend up to ±(V

REF+

– V

REF–

Following a single conversion, the LTC2453 can auto-matically

enter a sleep mode and reduce its power to less than 0.2µA.

If the user reads the ADC once a second, the LTC2453 con-

sumes an average of less than 50µW from a 2.7V supply.
