LM321MFX

LM321MFX 3 LOW POW ER SINGLE OPERATIONAL AMPLIFIER www.sot23.com.tw GENERAL DESCRIPTION These devices consist of two independent, high gain, internally frequency-compensated operational amplifiers designed operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3V to 36V, and VCC is at least 1.5V more positive than the input common-mode voltage, the low supply-current drain is independent of the magnitude of the power supply voltage. Applications One internally compensated OP amps Wide power supply range: 3V to 36V Large output voltage swing: 0V to Vcc-1.5V Low input bias current Low input offset voltage and offset current Internally frequency compensated for unity gain Short Circuit Protected Outputs Input common-mode voltage range includes ground SOT-23-5L package s - 电 - 子 Features 2021.6.15 (TOP VIEW) +IN 1 -VS 2 -IN 3 5 +VS 4 OUT + 台 舟 Pin Assignments _ SOT-23-5 1 Multivibrators Oscillators Switcching Telephone Portable Systems LM321MFX 3 LOW POW ER SINGLE OPERATIONAL AMPLIFIER www.sot23.com.tw Absolute Maximum Ratings Symbol Rating Unit Power Supply Voltage (Single Supply) VCC 40 V Power Supply Voltage (Split Supplies) Vcc, Vss ±20 V Input Differential Voltage Range VIDR ±20 V Input Common Mode Voltage Range VICR -0.3 to VCC V Output Short Circuit Duration TSC Continuous PD 500 mW TST -55 to +165 °C TOPJ -40 to +125 °C TJ 150 °C θJC 110 °C/W θJA 250 °C/W 子 Characteristics Power Dissipation Storage Temperature Range Operating Junction Temperature Junction Temperature Range Thermal Resistance from Junction to case 台 舟 电 Thermal Resistance from Junction to ambient 2021.6.15 2 LM321MFX 3 LOW POW ER SINGLE OPERATIONAL AMPLIFIER www.sot23.com.tw Electrical Characteristics (VCC = 5V, TA=25°C, unless otherwise specified) Typ Max Units Symbol Conditions (Note1) Min Input offset voltage(Note2) VIO VCC=5V to Max, VIC=VICR min, VO=1.4V 1 5 Average temperature coefficient of input offset voltage αVIO - 7 VO=1.4V - 2 IIN+ or IIN- 子 Characteristics Input offset current IIO Average temperature coefficient of input offset current αIIO Input bias current IIB Common-mode input voltage range Low-level output voltage Large-signal differential voltage amplification Common-mode rejection ratio VOL Crosstalk attenuation 台 Output current Short-circuit output current Supply current 2021.6.15 - -20 -250 nA - - VCC=Max, RL≧10KΩ 27 28 - - 5 20 KSVR VCC=5V to Max VOUT F=1KHz to 20KHz ICC - pA/°C 26 VCC=15V, VO=1V to 11V, RL≧2KΩ CMRR VCC=5V to Max, VIC=VICR min.
