Description: The SCP-5453 dual, matched internally
compensated universal precision operational amplifier
can be used in practically all precision applications
requiring multiple op amps. The SCP-5453 combines
picoampere bias currents (which are maintained over the
full –55°C to 125°C temperature range), microvolt offset
voltage (and low drift with time and temperature), low
voltage and current noise and low power dissipation.
Extremely high
common mode and power supply rejection ratios,
practically immeasurable warm-up drift, and the ability to
deliver 5mA load current with a voltage gain of a million,
round out the SCP-5453’s superb precision
specifications.
Tight matching is guaranteed on offset voltage,
noninverting bias currents and common mode and power
supply rejections. The all-around excellence of the SCP-
5453 eliminates the necessity of the time-consuming error
analysis procedure of precision system design in many
dual applications.
