low offset voltage, low I
current and low temperature drift
BIAS
making them the ideal choice for applications requiring both high
DC accuracy and AC performance. The combination of precision,
low noise, and small footprint provides the user with outstanding
value and flexibility relative to similar competitive parts.
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls, and industrial controls.
The ISL28117 single and ISL28217 dual are offered in an
8 Ld SOIC, MSOP and TDFN packages. The ISL28417 is offered
in 14 Ld SOIC, 14 Ld TSSOP and 16 Ld QFN packages. All
devices are offered in standard pin configurations and operate
over the extended temperature range from -40°C to +125°C.
