DUAL HIGH-SPEED DIFFERENTIAL COMPARATOR
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - The /LA711 is a Dual. Differential Voltage Comparator intended
primarily for core-memory sense amplifier applications. The device features high accuracy. fast response
times, large input voltage range, low powe~ consumption and compatibility with practically all
integrated logic forms. When used as a sense amplifier. the threshold voltage can be adjusted over a
wide range. almost independent of the integrated circuit characteristics. Independent strobing of each
comparator channel is provided, and pulse stretching on the output is easily accomplished. Other
applications of the dual comparator include a window discriminator in pulse height detectors and a
double·ended limit detector for automatic Go/No·Go test equipment. The /LA711. which is similar to
the IJA710 differential comparator, is constructed using the Fairchild Planar* epitaxial process.

NOTES:
1. Rating applies to ambient temperatures up to 70°C. Above 70°C ambient derate linearly at 6.3 mW/oC for the Metal Can, 8.3 mW/oC for
the DIP, and 7.1 mW/oC for the Flatpak.
2. The response time specified (see definitions) is for a 100 mV step input with 5 mV overdrive.
3. The input offset voltage is specified for a logic threshold as follows:
