The NTE992 is an internally compensated Norton operational amplifier in a 14-Lead DIP type package designed specifically for single positive power supply applications found in industrial control systems and automotive electronics. This device contains four independent amplifiers - making it ideal for applications such as active filters, multi-channel amplifiers, tachometers, oscillators, and other similar usages. * Wide Unity Gain Bandwidth: 4MHz Typ * Low Input Bias Current: 50nA Typ * High Open-Loop Gain: 1000V/V Min * Large Output Voltage Swing: (VCC -1) VP-P Input Currents (Iin+ or Iin-), Iin Power Dissipation (TA = +25°C), PD Operating Ambient Temperature Range, TA Storage Temperature Range, Tstg Electrical Characteristics: (TA = +25°C, VCC = +15V unless otherwise specified) f = 100Hz, RL = 5k Ohms, Note 1 Input Resistance (Inverting Input) Input Bias Current (Inverting Input) Vout High (Iin- = 0, Iin+ = 0) Vout Low (Iin- = 10µA, Iin+ = 0) VCC = Max Rating, RL = Infinity, Vout High (Iin- = 0, Iin+ = 0) Supply Current (All Four Amps) Open-loop voltage gain is defined as voltage gain from the inverting input to the output. Sink current is specified for linear operation. When the device is used as a comparator (non-linear operation) where the inverting input is overdriven, the sink current (low level output current) capability is typically 5mA. This specification indicates the current gain of the current mirror which is used as the non-inverting input. Input VBE match between the non-inverting and inverting inputs occurs for a mirror currnet (non-inverting input current) of approximately 10µA. Clamp transistors are included to prevent the input voltages from swinging below GND more than approximately -0.3V. The negative input currents that may result from large signal overdrive with capacitance input coupling must be limited externally to values of approximately 1mA. Negative input currents in excess of 4mA will cause the output to drop to a low voltage. These values apply for any one of the input terminals. If more than one of the input terminals are simultaneously driven negative, maximum currents are reduced. Common-mode biasing can be used to prevent negative input voltages. When used as a non-inverting amplifier, the minimum output voltage is the VBE of the inverting input transistor. (all content is the responsibility of the poster) |
