Description:
The NTE867 is a linear inetgrated circuit that has three major sections for interfacing television tuning systems: an input op−amp, a band−select switch, and an internally referenced quad−comparator. The op−amp output voltage has a wide dynamic range with a 3mA source or sink capability and can be clamped to three discrete levels in response to logic inputs. The op−amp also has internal bias reference and phase compensation. High impedance PMOS input transistors are protected by input limiting diode clippers.

FEATUREs:
● Input op−amp: high impedance PMOS input transistors and internal reference bias
● Low input bias current and internal diode protection at op−amp inputs
● High op−amp output voltage swing (0.7−28.0V) with 3mA source sink capability
● Three op−amp output voltage logic−controlled clamp levels
● Logic−controlled bandswitching with four seperate outputs
● Two bandswitch output current sinks
● Two bandswitch current−limited output current sources
● Internally referenced quad comparator
● Low drive current input requirement
● Low output leakage
● High output current sink capability
● Bipolar and PMOS processes on a single chip
