description
The uA748 is a general-purpose operational
amplifier that offers the same advantages and
attractive features as the uA741 except for internal
compensation. External compensation can be as
simple as a 30-pF capacitor for unity-gain
conditions and, when the closed-loop gain is
greater than one, can be changed to obtain wider
bandwidth or higher slew rate. This circuit features
high gain, large differential and common-mode
input voltage range, and output short-circuit
protection. Input offset-voltage adjustment can be
provided by connecting a variable resistor
between the offset null pins as shown in Figure 12.
The uA748C is characterized for operation from
0

C to 70
°
C; the uA748M is characterized for
operation over the full military temperature range
of –55
°
C to 125
°
C.
