RS358 Low Power Dual Operational Amplifiers DESCRIPTION FEATURES 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 32V, 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. • Two internally compensated OP amps • Internally frequency compensated for unity gain • Short circuit protection • Wide power supply range: 3VDC to 32VDC (Single supply) • Input common-mode voltage range includes ground • Large output voltage swing: 0VDC to Vcc-1.5VDC APPLICATIONS • • • • Electronic products Power supply Remote controller Consuming products BLOCK DIAGRAM Vcc 6uA 100uA Q5 6uA Q6 Cc Q7 Rsc Q2 Inverting Input Q3 Q4 Q1 Output Q11 Q13 + Non Inverting Input Q10 Q8 Q12 50uA Q9 Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, No. 233-1, Baociao Rd., Sindian Dist., New Taipei City 23145, Taiwan RS358 APPLICATION CIRCUIT Non Inverting DC Amplifier Voltage Follower AV=1+R1/R2 DC Summing Amplifier Squarewave Oscillator VO=V1+V2-V3-V4 Where (V1+V2)≥(V3+V4) To keep VO≥0V Function Generator Pulse Generator F=(R1+RC)/4CRfR1 if R3=R2*R1/(R2+R1) V1.0 2 May 2013 RS358 APPLICATION CIRCUIT High Input Z, DC Differential Amplifier DC Coupled Low-Pass RC Active Filter R1/R2=R4/R3 VO=1+R4/R3(V2-V1) As shown VO=2(V2-V1) f0=1KHz, Q=1, AV=2 Active Band-Pass Filter f0=1KHz, Q=50, AV=100 (40dB) V1.0 3 May 2013 RS358 ORDER INFORMATION Part Number RS358S Package Type 8-Pin, SOP, 150mil PIN CONFIGURATION PIN DESCRIPTION Pin Name OUT A Pin No. 1 INN A Inverting input A (-) 2 INP A Non inverting input A (+) 3 VEE Connect to GND or negative voltage. 4 INP B Non inverting input B (+) 5 INN B Inverting input B (-) 6 OUT B Output B 7 Supply voltage 8 VCC V1.0 Description Output A 4 May 2013 RS358 CHARACTERISTIC CURVES Large Signal Frequency Response Power Supply Current & Power Supply Voltage 14 ICC, Power Supply Current (mA)... 1.5 VOR, Output Voltage Range (Vpp)... 1.8 o Ta=25 C RL=∞ 1.2 0.9 0.6 0.3 12 10 8 RL=2K VCC=15V VEE=GND AV=-100 RI=1K RF=100K 6 4 2 0 0 0 5 10 15 20 25 30 35 1 10 VCC, Power Supply Voltage (V) Large Signal Open Loop Voltage Gain 60 40 20 0 10 100 1000 10000 100000 Output Voltage (V) ..
