LTC2351HUH-14#TRPBF DESCRIPTION
The LTC®2351-14 is a 14-bit, 1.5Msps ADC with six simultaneously sampled differential inputs. The device drawsonly 5.5mA from a single 3V supply, and comes in a tiny32-pin (5mm × 5mm) QFN package. A sleep shutdownmode further reduces power consumption to 12μW. Thecombination of low power and tiny package makes theLTC2351-14 suitable for portable applications.
