These circuits are general-purpose operational
amplifiers, each having high-impedance
differential inputs and a low-impedance output.
Component matching, inherent with silicon
monolithic circuit-fabrication techniques,
produces an amplifier with low-drift and low-offset
characteristics. Provisions are incorporated within
the circuit whereby external components may be
used to compensate the amplifier for stable
operation under various feedback or load
conditions. These amplifiers are particularly
useful for applications requiring transfer or
generation of linear or nonlinear functions.
The uA709A circuit features improved offset
characteristics, reduced input-current
requirements, and lower power dissipation when
compared to the uA709 circuit. In addition,
maximum values of the average temperature
coefficients of offset voltage and current are
specified for the uA709A.
The uA709C is characterized for operation from
0°C to 70°C. The uA709AM and uA709M are
characterized for operation over the full military
temperature range of –55°C to 125°C.

Full range for uA709C is 0°C to 70°C. Full range for uA709AM and uA709M is –55°C to 125°C.
NOTE 5: This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback.
