SBAS613A – MAY 2013 – REVISED DECEMBER 2013

ELECTRICAL CHARACTERISTICS

All minimum and maximum specifications are at TA = –40°C to +85°C, AVDD = 3 V, DVDD = 3 V, VREF = 5 V,

VCM = VREF / 2 V, and fSAMPLE = 100 kSPS, unless otherwise noted.

Typical specifications are at TA = +25°C, AVDD = 3 V, and DVDD = 3 V.
