The ISL70419SEH and ISL73419SEH contain four very high
Features
precision amplifiers featuring the perfect combination of low
• Electrically screened to DLA SMD# 5962-14226
noise vs power consumption. Low offset voltage, low I
BIAS
current, and low temperature drift make it the ideal choice for
applications requiring both high DC accuracy and AC
performance. The combination of high precision, low noise,
low power, and small footprint provides the user with
outstanding value and flexibility relative to similar competitive
parts.
