NTE867 Integrated Circuit BiMOS Input Op−Amp
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.
The band−select switch has two logic inputs controlling four outputs: VHF B+, VHF HIGH, SUPERBAND CATV, an...
