The ISL70218SEH, ISL70218SRH are dual, low-power
Features
precision amplifiers optimized for single-supply applications.
• DLA SMD# 5962-12222 (ISL70218SEH Only)
These op amps feature a common-mode input voltage range
extending to 0.5V below the V- rail, a rail-to-rail differential
input voltage range, and rail-to-rail output voltage swing, which
makes it ideal for single-supply applications where input
operation at ground is important.
• Wide single and dual supply range . . . . . . 3V to 42V, Abs. Max.
• Low current consumption . . . . . . . . . . . . . . . . .850µA, typical
• Low input offset voltage. . . . . . . . . . . . . . . . . . . . 40µV, typical
• Rail-to-rail output . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <10mV
These op amps feature low-power, low-offset voltage and
low-temperature drift, making it ideal for applications
requiring both high DC accuracy and AC performance. They are
designed to operate over a single supply range of 3V to 36V or a
split supply voltage range of +1.8V/-1.2V to ±18V. The
combination of precision and small footprint provides the user
with outstanding value and flexibility relative to similar
competitive parts.
• Rail-to-rail input differential voltage range for comparator
applications
• Operating temperature range. . . . . . . . . . . .-55°C to +125°C
• Below-ground (V-) input capability to -0.5V
• Low noise voltage . . . . . . . . . . . . . . . . . . . . 5.6nV/Hz, typical
• Low noise current. . . . . . . . . . . . . . . . . . . . 355fA/Hz, typical
Applications for these amplifiers include precision
instrumentation, data acquisition and precision power supply
controls.
• Offset voltage temperature drift . . . . . . . . .0.3µV/°C, typical
• No phase reversal
