Figure 6. ISL73141SEH Operational Timing Diagram

Unless otherwise noted: AVCC = 3.0V to 3.6V; DVCC = 2.2V to 3.6V, REF = 3.0V, GND = 0V, fSAMP = 750ksps, 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.
