LM 324 Description The LM324 consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits. Features • Wide range of supply voltages Low supply current drain independent of supply voltage Low input biasing current • Low input offset voltage and offset current • Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage PIP - 14 SOP - 14 DC voltage gain 100 V/ mV Typ Package Internal Block Digram PIN CONNECTIONS (top view) 14 OUT4 OUT1 1 IN1 (-) 2 IN1 (+) 3 VCC 4 IN2 (+) 5 _ IN2 (-) 6 2 OUT2 7 1 _ + _ 4 + 13 IN4 (-) 12 IN4 (+) 11 GND + + _ 10 IN3 (+) 3 9 IN3 8 BEIJING ESTEK ELECTRONICS CO.,LTD 1 LM 324 Electrical Characteristics (VCC= 5.0V V EE =GN D TA= 250C unless otherwise specified) Parameter Input Offset Input Offset Current Input Bias Current Common-mode input voltage range Symbol VIO Conditions Vcc=5V to MAX, Vic=VICR min, Vo=1.4V Min. 25 0 C Vo=1.4V 25 0 C IBIAS Vo=1.4V 25 0 C VI(R) Vcc=5V to MAX 25 0 C AVD Low-level output voltage RL=10K Ω Vcc=15V, Vo=1V to 11V Large-signal differential voltage amplification RL=2K Ω Common-Mode rejection ratio KSVR Supply voltage rejection ratio CMRR PSRR Vo1/Vo2 Crosstalk attenuation Io Output current Vcc=15V to MAX VIC=VICR min Vcc=5V to MAX f=1kHz to 20kHz Vcc=15V, VID = 1V, Vo=0 Vcc=15V, VID=-1V, Vo=0 Short-circuit out put current Ios Supply current (four amplifiers) Icc VID=-1V, Vo=200mA Vcc at 5V, GND at – 5V, Vo=0 Vo=2.5V, No load Vcc=MAX, Vo= 0.5Vcc, No load Max.
