AX358P

Page No. : 1/7 AX358P / AX358S Low Power Dual Operational Amplifiers Description These devices consist of two independent, high gain, internally frequencycompensated 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. 8-Lead Plastic DIP-8 Package Code: P • 8-Lead Plastic SO-8 Package Code: S Features • Two internally compensated OP amps • Internally frequency compensated for unity gain • Short Circuit Protected Outputs • W ide power supply range: 3VDC to 32VDC (Single supply) • Input common-mode voltage range includes ground • Large output voltage swing: 0VDC to Vcc-1.5VDC Logic Diagram (each amplifier) IN + IN - + - OUTPUT Pin Configurations 1 2 3 4 Out 8 7 Out Pin 1: Output 1 Pin 2: Inverting Input 1 Pin 3: Non Inverting Input 1 Pin 4: VEE Pin 5 : Non Inverting Input 2 Pin 6 : Inverting Input 2 Pin 7 : Output 2 Pin 8 : Vcc + 6 5 + Schematic Diagram Vcc 6uA 100uA Q5 6uA Cc Q7 Q6 Rsc Q2 Inverting Input + Non Inverting Input Q8 Q9 Q1 Q3 Q4 Q11 Output Q13 Q10 Q12 50uA AVANTICS - AX358 Series Specification No.: 050309-FE0011 Page No. : 2/7 Absolute Maximum Ratings (Ta=25oC, unless otherwise specified) Symbol VCC VCC, VEE VIDR VICR tSC TJ Tstg TA PD Parameter Power Supply Voltage (Single Supply) Power Supply Voltage (Split Supplies) Input Differential Voltage Range Input Common Mode Voltage Range Output Short Circuit Duration Junction Temperature Storage Temperature Range Operating Ambient Temperature Range Maximum Power Dissipation (DIP-8) Maximum Power Dissipation (SO-8) Range 32 ±16 ±32 -0.3 to +32 Continuous 150 -55 to +125 0 to +70 800 500 o Units VDC VDC VDC VDC C °C °C mW Electrical Characteristics (VCC=5V, VEE=Ground, Ta=25oC, unless otherwise specified) Symbol VIO IIO IIB AVOL CMR CS PSR ∆VIO/∆T ∆IIO/∆T VICR VOH VOL ICC ISource ISink ICC ISC Parameter Input Offset Voltage Input Offset Current Input Bias Current Large Signal Voltage Gain Common-Mode Rejection Ratio Channel Separation Power Supply Rejection Average Temperature Coefficient of Input Offset Voltage Average Temperature Coefficient of Input Offset Current Input Common Mode Voltage Range Output Voltage (High Limit) Output Voltage (Low Limit) Supply current Output Source Current Output Sink Current Power Supply Current Output Short Circuit to Ground Test Conditions VCC=5V~30V, VICR=0V~VCC-1.5V, VO=1.4V, RS=0Ω IIN(+)-IIN(-) IIN(+) or IIN(-) VCC=15V, RL=2KΩ VCM=0V~VCC-1.5V 1KHz≤f≤20KHz VCC=5V~30V RS=0Ω RS=0Ω VCC=30V VCC=30V, RL=2KΩ VCC=30V, RL=10KΩ RL=10KΩ RL=∞,VCC=30V VCC=15V, VIN+=1V, VIN-=0V, VO=2V VCC=15V, VIN+=0V, VIN-=1V, VO=2V VCC=30V, Ta=Thigh to Tlow VCC=5V, Ta=Thigh to Tlow VCC=5V, GND at -5V, VO=0V 26 27 20 10 27 28 5 1 40 20 1 0.6 40 AX358P/S Min 25 65 65 Typ 2 35 100 85 -120 100 7 10 Max 7 30 200 VCC-2V 20 2 2 1.2 60 Unit mV nA nA V/mV dB dB dB uV/oC pA/oC V V mV mA mA mA mA mA mA AVANTICS - AX358 Series Specification No.: 050309-FE0011 Page No. : 3/7 Characteristics Curve Power Supply Current & Power Supply Voltage 1.8 14 Large Signal Frequency Response Ta=25 C R L =∞ o V OR, Output Voltage Range (Vpp).. .
