CO324 Quad Ground Sense Operational Amplifier The CO324 is monolithic IC with four built-in operational amplifiers featuring internal phase compensation. Either a dual or single power supply can be driven, and these products can be driven by a digital system 5V single power supply. These products can be used in a wide range of administrative and industrial applications, including transducer amplifiers and DC amplifiers. Applications •Ground sensing type pre-amplifiers Active filters DC amplifiers Pulse generators. •1)Features Wide range of operating power supply voltages and single power supply drive enabled. (single power supply: 3 to 30V, dual power supply: ± 1.5 to ± 15V) 2) Common-mode input voltage can be operated from the ground level. 3) Differential input voltage can be operated up to the power supply voltage level. 4) Low current dissipation. (IQ = 0.6mA) 5) Low offset voltage and offset current. (VIO = 2mV, IIO = 5nA typ.) 6) Four operational amplifiers with phase compensation are built into the DIP / SOP Pin 14. 7) Compatible with model 324 operational amplifiers of other manufacturers. •Block diagram OUT1 1 – IN1 2 1 4 – + + – 14 OUT4 13 – IN4 + IN1 3 12 + IN4 VCC 4 11 VEE + IN2 5 10 + IN3 9 – IN3 8 OUT3 – IN2 6 OUT2 7 – + + – 2 3 * All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: [email protected] Tel:886-3-3214525 Http: www.ceramate.com.tw Page 1 of 5 Rev 1.0 Apr. 28, 2003 Fax:886-3-3521052 CO324 Quad Ground Sense Operational Amplifier •Internal circuit configuration VCC – IN OUT + IN VEE •Absolute maximum rating (Ta = 25°C) Parameter Limits Symbol CO324 (DIP-14) CO324 (SOP-14) Unit Power supply voltage Vcc 36(±16) 36(±16) V Power dissipation Pd VID 450* ±VCC mW Differential input voltage 720* ±VCC VI -0.3~Vcc -0.3~Vcc Common-mode input voltage V Operating temperature Topr -40~+85 -40~+85 V ℃ Storage temperature Tstg -55~+125 -55~+125 ℃ * Refer to the Pd characteristics diagram. ● ORDERING INFORMATION CO324 X BLANK: SO-14 N:DIP14 A:SO-14 & TAPING * All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: [email protected] Tel:886-3-3214525 Http: www.ceramate.com.tw Page 2 of 5 Rev 1.0 Apr 28, 2003 Fax:886-3-3521052 CO324 Quad Ground Sense Operational Amplifier •Electrical characteristics (unless otherwise noted, Ta = 25°C, V CC Symbol Min.
