LM321G-AE5-R

UNISONIC TECHNOLOGIES CO., LTD LM321 LINEAR INTEGRATED CIRCUIT LOW POWER SINGLE OP AMP  DESCRIPTION The UTC LM321’s quiescent current is only 430µA (5V). The UTC LM321 brings performance and economy to low power systems, With a high unity gain frequency and a specified 0.4V/µs slew rate. The input common mode range includes ground and therefore the device is able to operate in single supply applications as well as in dual supply applications. It is also capable of comfortably driving large capacitive loads.  FEATURES * Low supply current 430µA * VCC=5V, TA=25°C. Typical values unless specified. * Gain-Bandwidth product 1MHz * Low input bias current 45nA * Wide supply voltage range +3V~+32V * Stable with high capacitive loads  ORDERING INFORMATION Ordering Number Lead Free Halogen Free LM321L-AE5-R LM321G-AE5-R  Package Packing SOT-23-5 Tape Reel MARKING www.unisonic.com.tw Copyright © 2017 Unisonic Technologies Co., Ltd 1 of 7 QW-R104-007.E LM321 LINEAR INTEGRATED CIRCUIT  PIN CONFIGURATION  PIN DESCRIPTION PIN NO. 1 2 3 4 5  PIN NAME +IN V-IN OUTPUT V+ DESCRIPTION Non-inverting input Ground inverting input Output Power supply BLOCK DIAGRAM 5 V+ +IN 1 + V- 2 - -IN 3 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 4 OUTPUT 2 of 7 QW-R104-007.E LM321  LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage (V+ - V−) VCC 32 V Differential Input Voltage VI(DIFF) ±Supply Voltage V Input Voltage VIN -0.3~+32 V Input Current (VIN=50dB (V+=15V, RL=2kΩ 25 Large Signal Voltage Gain AV VO=1.4V~11.4V) 15 Power Supply Rejection Ratio PSRR RS≤10kΩ, V+≤5V~30V 65 Common Mode Rejection Ratio CMRR RS≤10kΩ 65 V+=30V, RL=2kΩ 26 VOH + Output Swing 27 V =30V, RL=10kΩ VOL V+=5V, RL=10kΩ V+=5V Supply Current, No Load IS V+=30V Output Current Sourcing ISOURCE VID=+1V, V+=15V, VO=2V 20 VID=-1V, V+=15V, VO=2V 10 Output Current Sinking ISINK + 12 VID=-1V, V =15V, VO=0.2V Output Short Circuit to Ground IO V+=15V (Note 6) V+=15V, RL=2kΩ, VIN=0.5~3V, Slew Rate SR CL=100pF, Unity Gain V+=30V, f=100kHz, VIN=10mV, Gain Bandwidth Product GBW RL=2kΩ, CL=100pF Phase Margin φm f=1kHz, AV=20dB, RL=2kΩ, Total Harmonic Distortion THD VO=2VPP, CL=100pF, V+=30V Equivalent Input Noise Voltage en f=1kHz, RS=100Ω, V+=30V TYP MAX (Note 2) (Note 1) 2 7 45 250 5 50 V+ -1.5 100 100 85 28 5 0.430 0.660 40 20 100 40 20 1.15 2.85 85 UNIT mV nA nA V V/mV V/mV dB dB V V mV mA mA mA mA µA mA 0.4 V/µs 1 MHz 60 deg 0.015 % 40 nV Hz Notes: 1. All limits are specified by testing or statistical analysis. 2. Typical values represent the most likely parametric norm. 3. VO  1.4V, RS=0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V~V+ -1.5V) at 25°C. 4. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 5. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The upper end of the common-mode voltage range is V+-1.5V at 25°C, but either or both inputs can go to +32V without damage, independent of the magnitude of V+. 6. Short circuits from the output V+ can cause excessive heating and eventual destruction. When considering short circuits to ground the maximum output current is approximately 40mA independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous short circuits can exceed the power dissipation ratings and cause eventual destruction.
