ISL73141SEHMF7 - 5V Operation

Unless otherwise noted: AVCC = 5.0V; DVCC = 2.5V, REF = 4.096V, GND = 0V, fSAMP = 1Msps, AIN = -1dBFS.Boldface limits apply across

the operating temperature range, -55°C to +125°C by production testings; over a total ionizing dose of 75krad(Si) at +25°C with

exposure at a low dose rate of <10mrad(Si)/s.
