LM146 LM246 LM346
PROGRAMMABLE QUAD BIPOLAR OPERATIONAL AMPLIFIER
s PROGRAMMABLE ELECTRICAL CHARAC-
TERISTICS
s LOW SUPPLY CURRENT (250µA/amplifier)
s GAIN-BANDWITH PRODUCT : 1MHz
s LARGE DC VOLTAGE GAIN : 120dB s LOW NOISE VOLTAGE : 28nV/√Hz
) s WIDE POWER SUPPLY RANGE / ±1.5V to t(s ±22V
s CLASSE AB OUTPUT STAGE. NO
c CROSS-OVER DISTORTION du s OVERLOAD PROTECTION FOR INPUTS ro AND OUTPUTS P DESCRIPTION te The LM346 consists of four independent, high
gain, internally compensated, low power program-
le mable amplifiers. Two external resistors (Rset) alo low the user to program the gain-bandwith prodbs uct, slew rate, supply current, input bias current,
input offset current and input noise.
