DESCRIPTIO
The LT
that can be used in practically all precision applications.
The LT1008 combines for the first time, 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, and the
ability to deliver 5mA load current with high voltage gain
round out the LT1008’s superb precision specifications.
The all around excellence of the LT1008 eliminates the
necessity of the time consuming error analysis procedure
of precision system design in many applications; the
LT1008 can be stocked as the universal precision op amp.
The LT1008 is externally compensated with a single ca-
pacitor for additional flexibility in shaping the frequency
response of the amplifier. It plugs into and upgrades all
standard LM108A/LM308A applications. For an internally
compensated version with even lower offset voltage but
otherwise similar performance see the LT1012.
