Detailed Product Description

 

LM146

LM246 - LM346

PROGRAMMABLE QUAD BIPOLAR OPERATIONAL AMPLIFIERS

 

  • PROGRAMMABLE ELECTRICAL CHARACTERISTICS
  • BATTERY POWERED OPERATION
  • LOW SUPPLY CURRENT (250µA/amplifier)
  • GAIN-BANDWIDTH PRODUCT : 1MHz
  • LARGE DC VOLTAGE GAIN : 120dB
  • LOW NOISE VOLTAGE : 28nV/VHz
  • WIDE POWER SUPPLY RANGE : ±1.5V to ±22V
  • CLASSE AB OUTPUT STAGE. NO CROSSOVER DISTORTION
  • OVERLOAD PROTECTION FOR INPUTS AND OUTPUTS

DESCRIPTION

The LM346consists of four independent, high gain, internally compensated, low power programmable amplifiers. Two external resistors (Rset) allow the user to program the gain-bandwith product, slew rate, supply current, input bias current, input offset current and input noise. For example the user can trade-off supply current for bandwidth or optimize noise figure for a given source resistance. In a similar way other amplifier characteristics can be tailored to the application.

Except for the two programming pins at the end of the package the LM346 pin out is the same as the LM324 and LM348.

 

PROGRAMMING EQUATIONS :

Total supply current = 1mA (Iset = 10µA)

Gain-bandwidthproduct = 1MHz (Iset = 10µA)

Slew rate = 0.5V/µs (Iset = 10µA)

Input bias current ≈30 nA (Iset = 10µA)

Iset = current into pin 8 and pin 9

Iset = VCC + − VCC − 0.6V / Rset

Notes :

1. For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.

2. Any of the amplifier outputs can be shorted to ground indefinitly ; however more than one should not be simultaneously shorted as the maximum junction temperature will be exceeded.
