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. Features: D Input op-amp: high impedance PMOS input transistors and internal reference bias D Low input bias current and internal diode protection at op-amp inputs D High op-amp output voltage swing (0.7-28.0V) with 3mA source sink capability D Three op-amp output voltage logic-controlled clamp levels D Logic-controlled bandswitching with four seperate outputs D Two bandswitch output current sinks D Two bandswitch current-limited output current sources D Internally referenced quad comparator D Low drive current input requirement D Low output leakage D High output current sink capability D Bipolar and PMOS processes on a single chip Absolute Maximum Ratings: (TA = +25C, unless otherwise specified) Supply Current, ISS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20mA Supply Voltage (Pin 8), VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Supply Voltage (Pin 12), VDD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8V Device Dissipation Perk Package, PD Up to 55C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 750mW Above 55C (Derate Linearly) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.9mW/C Operating Ambient Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +70C Storage Ambient Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C
