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, and UHF B+. The VHF B+ and UHF B+ outputs are current sources which are short−circuit protected by current limiting. VHF HIGH and SUPERBAND CATV outputs are current sinks with
low off−state leakage. The quad comparator features internal reference bias, low output leakage, and
a 6mA current sinking capability. The outputs of two of the comparators are internally connected to
form a window comparator.
