General Description
The CLC502 is an operational amplifier designed for low-gain
applications requiring output voltage clamping. This feature allows
the designer to set maximum positive and negative output voltage
levels for the amplifier - thus allowing the CLC502 to protect
downstream circuitry, such as delicate converter systems, from
destructive transients or signals which would otherwise cause saturation. The overload recovery time of only 8ns permits systems to resume operation quickly after overdrive.
High-accuracy systems will also benefit from the CLC502's fast,accurate settling. Settling to 0.0025% in 25ns (32ns guaranteed over temperature), the CLC502 is ideal as the input amplifier in high-accuracy (12 bits and above) A/D systems. Unlike most other high-speed op amps, the CLC502 is free of settling tails. And, as the settling plots show, settling to 0.01% accuracy is an even faster18ns typical.
The CLC502 is also useful in other applications which require low-gain amplification(+1 to 8) and the clamping or overload recovery features. For example, even low-resolution imaging circuits, which often have to cope with overloading signal levels, can benefit from clamping and overload recovery.
The Cl C502 is available in several versions to meet a variety of requirements.A three-letter suffix determines the version:
CLC502AJP -40°C to +85° 8-pin plastic DIP
CCLC502AJE -40°C to +85°C 8-pin plastic SOIC
