LM324ADT

LM224A - LM324A Low Power Quad Operational Amplifiers ■ ■ ■ ■ ■ ■ ■ ■ ■ Wide gain bandwidth: 1.3MHz Large voltage gain: 100dB Very low supply current/ampli: 375µA Low input bias current: 20nA Low input offset voltage: 3mV max. Low input offset current: 2nA Wide power supply range: Single supply: +3V to +30V Dual supplies: ±1.5V to ±15V Input common-mode voltage range includes ground ESD internal protection: 2KV N DIP14 (Plastic Package) Description These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers. They operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. All the pins are protected against electrostatic discharges up to 2KV (as a consequence, the input voltages must not exceed the magnitude of VCC+ or VCC-.)

The maximum output current is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers. 3) This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. this transistor action can cause the output voltages of the op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V. 3/16 LM224A-LM324A 3 Electrical Characteristics Electrical Characteristics Table 2: VCC+ = +5V, VCC-= Ground, Vo = 1.4V, Tamb = +25°C (unless otherwise specified Symbol Vio Input Offset Voltage - note Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Input Offset Current Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Input Bias Current - note 2 Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Large Signal Voltage Gain VCC+ = +15V, RL = 2kΩ, Vo = 1.4V to 11.4V Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Supply Voltage Rejection Ratio (Rs ≤ 10kΩ) SVR VCC+ = 5V to 30V Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Supply Current, all Amp, no load Tamb = +25°C VCC = +5V VCC = +30V Tmin ≤ Tamb ≤ Tmax VCC = +5V VCC = +30V Input Common Mode Voltage Range VCC = +30V - note 3 Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Common Mode Rejection Ratio (Rs ≤ 10kΩ) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Output Current Source (Vid = +1V) VCC = +15V, Vo = +2V Output Sink Current (Vid = -1V) VCC = +15V, Vo = +2V VCC = +15V, Vo = +0.2V High Level Output Voltage VCC = +30V Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Tamb = +25°C Tmin ≤ Tamb ≤ Tmax VCC = +5V, RL = 2kΩ Tamb = +25°C Tmin ≤ Tamb ≤ Tmax 65 65 110 1 Parameter Min.

This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3) The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC+ - 1.5V, but either or both inputs can go to +32V without damage. 4) Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitance increases at higher frequences. 5/16 LM224A-LM324A Figure 3: Input bias current vs. ambient temperature INPUT BIAS CURRENT versus AMBIENT TEMPERATURE IB (nA) Electrical Characteristics Figure 6: Current limiting 24 21 18 15 12 9 6 3 0 -55-35-15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (°C) Figure 4: Input voltage range Figure 7: Supply current SUPPLY CURRENT 4 VCC SUPPLY CURRENT (mA) 3 mA - ID 2 + 1 Tamb = 0°C to +125°C Tamb = -55°C 0 10 20 30 POSITIVE SUPPLY VOLTAGE (V) Figure 5: Gain bandwidth product Figure 8: Common mode rejection ratio 6/16 Electrical Characteristics Figure 9: Electrical curves LM224A-LM324A 7/16 LM224A-LM324A Figure 10: Input current Electrical Characteristics Figure 12: Voltage gain Figure 11: Power supply & common mode rejection ratio Figure 13: Large signal voltage gain 8/16 Typical Single - Supply Applications 4 Typical Single - Supply Applications LM224A-LM324A Figure 17: High input Z adjustable gain DC instrumentation amplifier Figure 14: AC coupled interting amplifier if R1 = R5 and R3 = R4 = R6 = R7 Figure 15: AC coupled non inverting amplifier 2R 1 e0 = 1 + ---------R 2 (e2 -e1) As shown e0 = 101 (e2 - e1).

Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the NOMINAL performance of a TYPICAL device within SPECIFIED OPERATING CONDITIONS (i.e. temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main parameters of the product. Data issued from macromodels used outside of its specified conditions (Vcc, Temperature, etc) or even worse: outside of the device operating conditions (Vcc, Vicm, etc) are not reliable in any way. ** Standard Linear Ics Macromodels, 1993. ** CONNECTIONS : * 1 INVERTING INPUT * 2 NON-INVERTING INPUT * 3 OUTPUT * 4 POSITIVE POWER SUPPLY * 5 NEGATIVE POWER SUPPLY .SUBCKT LM324 1 2 3 4 5 *************************** .MODEL MDTH D IS=1E-8 KF=3.104131E-15 CJO=10F * INPUT STAGE CIP 2 5 1.000000E-12 CIN 1 5 1.000000E-12 EIP 10 5 2 5 1 EIN 16 5 1 5 1 RIP 10 11 2.600000E+01 RIN 15 16 2.600000E+01 RIS 11 15 2.003862E+02 DIP 11 12 MDTH 400E-12 DIN 15 14 MDTH 400E-12 VOFP 12 13 DC 0 VOFN 13 14 DC 0 IPOL 13 5 1.000000E-05 CPS 11 15 3.783376E-09 DINN 17 13 MDTH 400E-12 VIN 17 5 0.000000e+00 DINR 15 18 MDTH 400E-12 VIP 4 18 2.000000E+00 FCP 4 5 VOFP 3.400000E+01 FCN 5 4 VOFN 3.400000E+01 FIBP 2 5 VOFN 2.000000E-03 FIBN 5 1 VOFP 2.000000E-03 * AMPLIFYING STAGE FIP 5 19 VOFP 3.600000E+02 FIN 5 19 VOFN 3.600000E+02 RG1 19 5 3.652997E+06 RG2 19 4 3.652997E+06 CC 19 5 6.000000E-09 DOPM 19 22 MDTH 400E-12 DONM 21 19 MDTH 400E-12 HOPM 22 28 VOUT 7.500000E+03 VIPM 28 4 1.500000E+02 HONM 21 27 VOUT 7.500000E+03 VINM 5 27 1.500000E+02 EOUT 26 23 19 5 1 VOUT 23 5 0 ROUT 26 3 20 COUT 3 5 1.000000E-12 DOP 19 25 MDTH 400E-12 VOP 4 25 2.242230E+00 DON 24 19 MDTH 400E-12 VON 24 5 7.922301E-01 ENDS 12/16 Package Mechanical Data 6 Package Mechanical Data LM224A-LM324A 6.1 DIP14 Package Plastic DIP-14 MECHANICAL DATA mm.
