Two external • Battery-Powered Operation resistors (RSET) allow the user to program the gain bandwidth product, slew rate, supply current, input • Low Supply Current: 350 μA/Amplifier bias current, input offset current and input noise. For • Ensured Gain Bandwidth Product: 0.8 MHz Min example, the user can trade-off supply current for • Large DC Voltage Gain: 120 dB bandwidth or optimize noise figure for a given source resistance. In a similar way, other amplifier • Low Noise Voltage: 28 nV/ √Hz characteristics can be tailored to the application. • Wide Power Supply Range: ±1.5V to ±22V Except for the two programming pins at the end of • Class AB Output Stage–No Crossover the package, the LM146 pin-out is the same as the Distortion LM124 and LM148. • Ideal Pin Out for Biquad Active Filters • Input Bias Currents are Temperature Compensated Connection Diagram Figure 1. Dual-In-Line Package - Top View See Package Number NFE0016A, D0016A or N16A PROGRAMMING EQUATIONS Total Supply Current = 1.4 mA (ISET/10 μA) Gain Bandwidth Product = 1 MHz (ISET/10 μA) Slew Rate = 0.4V/ μs (ISET/10 μA) Input Bias Current ≃ ≃ 50 nA (ISET/10 μA) ISET = Current into pin 8, pin 9 (see Schematic Diagram) (1) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
