nn Tiny 10-Lead MS Package The LTC®1403/LTC1403A are 12-bit/14-bit, 2.8Msps serial ADCs with differential inputs. The devices draw only
4.7mA from a single 3V supply and come in a tiny 10-lead
MS package. A Sleep shutdown feature lowers power
consumption to 10µW. The combination of speed, low
power and tiny package makes the LTC1403/LTC1403A
suitable for high speed, portable applications. nn The 80dB common mode rejection allows users to eliminate
ground loops and common mode noise by measuring
signals differentially from the source. Applications The devices convert 0V to 2.5V unipolar inputs differentially.
The absolute voltage swing for +AIN and –AIN extends from
ground to the supply voltage. Automotive …
