They are offered in industry standard pinouts in 8 Ld SOIC, 8 Ld MSOP and 14 Ld SOIC packages. Applications for this amplifier include active filters, medical and analytical instrumentation, power supply controls, and industrial controls.. Operating Voltage Range The devices are designed to operate over the 4.5V (±2.25V) to 40V (±20V) range over the -40°C to +125°C temperature range. For best amplifier performance, decouple the power supply with a 0.01µF or larger capacitors by placing them close to the supply pins of the amplifier. Input ESD Diode Protection The input terminals (IN+ and IN-) have internal ESD protection diodes to the positive and negative supply rails, series connected 500Ω current limiting resistors and an anti-parallel diode pair across the inputs. The series resistors limit the high feed-through currents that can occur in pulse applications when the input dV/dT exceeds the 0.4V/µs slew rate of the amplifier. Without the series resistors, the input can forward-bias the anti-parallel diodes causing current to flow to the output resulting in severe distortion and possible diode failure. In applications where one or both amplifier input terminals are at risk of exposure to high voltages beyond the power supply rails, current limiting resistors may be needed at the input terminal to limit the current through the power supply ESD diodes to 20mA max. 6 September 27, 2011 FN7854.0 ISL28325, ISL28345 Revision History The revision history provided is for informational purposes only and is believed to be accurate, but not warranted.
