The maximum output current is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers. 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.

This current is essentially constant, independent of the state of the output, so no loading charge change exists on the input lines 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. 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. + INPUT VOLTAGE RANGE INPUT BIAS CURRENT versus AMBIENT TEMPERATURE 24 21 18 15 12 9 6 3 0 15 INPUT VOLTAGE (V) IB (nA) 10 SUPPLY CURRENT (mA) OUTPUT CURRENT (mA) VCC IO + 50 40 30 20 10 -55 -35 15 4 70 0 10 SUPPLY CURRENT CURRENT LIMITING (Note 1) 60 5 POWER SUPPLY VOLTAGE (±V) 90 - Positive 0 AMBIENT TEMPERATURE (°C) 80 Négative 5 -55-35-15 5 25 45 65 85 105 125 ID mA 3 - 2 + Tamb = 0°C to +125°C 1 Tamb = -55°C -15 5 25 45 65 85 105 TEMPERATURE (°C) 4/10 dB 120 + 125 0 10 20 POSITIVE SUPPLY VOLTAGE (V) 30 LM2902W GAIN BANDWIDTH PRODUCT VOLAGE FOLLOWER PULSE RESPONSE 4 OUTPUT VOLTAGE (V) 1.35 1.30 1.25 1.2 1.15 1.1 1.05 1 -95 -9 RL 2 k Ω VCC = +15V 3 2 1 0 3 -55-35-15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (°C) INPUT VOLTAGE (V) GAIN BANDWIDTH PRODUCT (MHz) GBP (mhz) 2 1 0 OUTPUT VOLTAGE (V) COMMON MODE REJECTION RATIO (dB) 80 +7.5V 100kΩ 100 Ω 60 - 40 100 Ω eI eO + 100kΩ 20 VCC = +5V VCC = +15V VCC = +30V 1 v cc v cc /2 - 0.1 IO Tamb = +25°C 0,001 1M 100K 140 VO + 80 VCC = 30V & -55°C Tamb +125°C 60 40 20 VCC = +10 to + 15V & -55°C Tamb +125°C OUTPUT VOLTAGE (mV) VCC VI VCC/2 1 10 100 1k 10k 100k eO el - 50pF 400 Input 350 Output 300 1M Tamb = +25°C VCC = 30 V 250 10M 0 1 2 FREQUENCY (Hz) - +15V VO VI +7V + 2k Ω 10 5 0 1k 10k 4 5 6 7 8 OUTPUT CHARACTERISTICS 100k FREQUENCY (Hz) 1M 8 V CC 7 6 TO VCC+ (V) 100k Ω OUTPUT VOLTAGE REFERENCED 20 15 3 TIME (µs) LARGE SIGNAL FREQUENCY RESPONSE 1k Ω 100 + 450 0 1.0 10 500 10M Ω - 100 0,1 VOLTAGE FOLLOWER PULSSE RESPONSE (SMALL SIGNAL) OPEN LOOP FREQUENCY RESPONSE (NOTE 3) 0.1µF 0,01 OUTPUT SINK CURRENT (mA) FREQUENCY (Hz) 120 VO + 0.01 10K 1K 40 +7.5V 0 100 OUTPUT SWING (Vpp) 30 OUTPUT CHARACTERISTICS 10 120 100 20 TIME (µ s) COMMON MODE REJECTION RATIO VOLTAGE GAIN (dB) 10 V CC /2 5 + VO IO - 4 3 2 Independent of V CC T amb = +25°C 1 0,001 0,01 0,1 1 10 100 OUTPUT SOURCE CURRENT (mA) 5/10 LM2902W TYPICAL SINGLE - SUPPLY APPLICATIONS AC COUPLED INVERTING AMPLIFIER INPUT CURRENT (nA) 100 75 Rf 100kΩ 50 25 Co 1/4 LM2902 Tamb= +25°C 0 10 20 30 POSITIVE SUPPLY VOLTAGE (V) eI ~ R2 VCC 100kΩ Rf R1 (as shown AV = -10) R1 10kΩ CI A V= - 2VPP 0 eo RB 6.2kΩ R3 100kΩ RL 10k Ω C1 10µF 160 VOLTAGE GAIN (dB) R L = 20k Ω 120 R L = 2kΩ 80 AC COUPLED NON-INVERTING AMPLIFIER 40 R1 100kΩ 0 10 20 30 POSITIVE SUPPLY VOLTAGE (V) POWER SUPPLY & COMMON MODE REJECTION RATIO (dB) 115 110 105 100 95 90 85 80 75 A V= 1 + R2 R1 (as shown A V = 11) C1 0.1µF Co 1/4 LM2902 CI POWER SUPPLY & COMMON MODE REJECTION RATIO (dB) 120 R2 1MΩ RL 10kΩ RB 6.2kΩ R3 1MΩ eI ~ SVR 2VPP 0 eo R4 100kΩ VCC C2 10µF R5 100kΩ CMR 70 -55-35-15 5 25 45 65 85 105 125 NON-INVERTING DC GAIN AMBIENT TEMPERATURE (°C) 6/10 LARGE SIGNAL VOLTAGE GAIN 120 A V = 1 + R2 R1 (As shown A V = 101) 10k Ω 1/4 LM2902 115 eO +5V R2 1M Ω O R1 10kΩ e 105 (V) 110 -55 LARGE SIGNAL VOLTAGE GAIN Avd (dB) 100 -55-35-15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (°C) 0 e I (mV) LM2902W DC SUMMING AMPLIFIER e1 ACTIVER BADPASS FILTER R1 100kΩ 100kΩ C1 330pF 100kΩ e2 1/4 LM2902 eO 1/4 LM2902 R5 470kΩ R4 10MΩ e1 1/4 LM2902 100kΩ C2 330pF e3 R3 10kΩ 100kΩ R6 470kΩ eO 100kΩ e4 1/4 LM2902 R7 100kΩ V CC 100kΩ C3 10µF R8 100kΩ eo = e1 + e2 - e3 - e4 where (e1 + e2) ≥ (e3 + e4) to keep eo ≥ 0V Fo = 1kHz Q = 50 Av = 100 (40dB) HIGH INPUT Z, DC DIFFERENTIAL AMPLIFIER HIGH INPUT Z ADJUSTABLE GAIN DC INSTRUMENTATION AMPLIFIER R1 100k Ω R3 100k Ω 1/4 LM2902 e1 Gain adjust R2 2k Ω R1 100kΩ 1/4 LM2902 eO 1/4 LM2902 R4 100kΩ R2 100kΩ R4 100k Ω R3 100kΩ 1/4 LM2902 +V1 +V2 R5 100k Ω eo = [ 1 + Vo R4 ] (e2 - e1) R3 As shown eo = (e2 - e1) R6 100k Ω 1/4 LM2902 R7 100k Ω e2 If R1 = R5 and R3 = R4 = R6 = R7 eo = [ 1 + 2R1 ] (e2 - e1) R2 As shown eo = 101 (e2 - e1) LOW DRIFT PEAK DETECTOR USING SYMMETRICAL AMPLIFIERS TO REDUCE INPUT CURRENT (GENERAL CONCEPT) 1/4 IB I 1/4 I B LM2902 1/4 LM2902 eI C * 1µF ZI 2I B R 1MΩ IB IB 3R 3MΩ eo I B LM2902 2N 929 0.001µ F 0.001µF IB * Polycarbonate or polyethylene eI Zo 2I B 2N 929 eo I IB IB 3MΩ 1/4 LM2902 Input current compensation IB 1/4 LM2902 Aux. amplifier for input current compensation 1.5MΩ 7/10 LM2902W PACKAGE MECHANICAL DATA Plastic DIP-14 MECHANICAL DATA mm. inch DIM.
