LM146/LM346 Programmable Quad Operational Amplifiers Check for Samples: LM146, LM346 FEATURES DESCRIPTION 1
The LM146 series of quad op amps consists of four
• (I 2 SET=10 μA)
independent, high gain, internally compensated, low
• Programmable Electrical Characteristics
power, programmable amplifiers. 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
• Low Noise Voltage: 28 nV/√Hz
resistance. In a similar way, other amplifier 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 =
