SGM8621 SGM8622 SGM8623 SGM8624 PRODUCT DESCRIPTION The SGM8621(single), SGM8622 (dual), SGM8623 (single with shutdown) and SGM8624 (quad) are low noise, low voltage, and low power operational amplifiers, that can www.DataSheet4U.com be designed into a wide range of applications. The SGM8621/2/3/4 have a high gain-bandwidth product of 3MHz, a slew rate of 1.7V/µs, and a quiescent current of 250µA/amplifier at 5V. The SGM8623 has a power-down disable feature that reduces the supply current to 150nA. The SGM8621/2/3/4 are designed to provide optimal performance in low voltage and low noise systems. They provide rail-to-rail output swing into heavy loads. The input common-mode voltage range includes ground, and the maximum input offset voltage is 3mV for SGM8621/2/3/4. They are specified over the extended industrial temperature range (−40°C to +125°C). The operating range is from 2.5V to 5.5V. The single version, SGM8621/8623, is available in SC70-5, SO-8 and SOT23-5(6) packages. The dual version SGM8622 is available in SO-8 and MSOP-8 packages. The quad version SGM8624 is available in SO-16 and TSSOP-16 packages. 250µA, 3MHz, Rail-to-Rail I/O CMOS Operational Amplifier FEATURES • Low Cost • Rail-to-Rail Input and Output 0.7mV Typical VOS • High Gain-Bandwidth Product: 3MHz • High Slew Rate: 1.7V/µs • Settling Time to 0.1% with 2V Step: 2.1 µs • Overload Recovery Time: 1µs • Low Noise : 12 nV/ Hz • Operates on 2.5 V to 5.5V Supplies • Input Voltage Range = - 0.1 V to +5.6 V with VS = 5.5 V • Low Power 250µA/Amplifier Typical Supply Current SGM8623 150nA when Disabled • Small Packaging SGM8621 Available in SC70-5, SOT23-5 and SO-8 SGM8622 Available in MSOP-8 and SO-8 SGM8623 Available in SOT23-6and SO-8 SGM8624 Available in TSSOP-16 and SO-16 PIN CONFIGURATIONS (Top View) SGM8621 OUT -VS 1 2 4 SOT23-5 /SC70-5 -IN +IN 3 4 6 5 NC = NO CONNECT 5 +VS NC -IN 1 2 SGM8621/8623 8 7 DISABLE (SGM8623 ONLY) +VS OUT NC +IN 3 APPLICATIONS Sensors Audio Active Filters A/D Converters Communications Test Equipment Cellular and Cordless Phones Laptops and PDAs Photodiode Amplification Battery-Powered Instrumentation OUT -VS +IN 1 2 3 SGM8623 8623 SOT23-6 6 5 4 +VS DISABLE -IN -VS SO-8 SGM8624 OUT A -IN A 1 2 3 4 5 6 7 8 NC = NO CONNECT 16 OUT D 15 -IND SGM8622 OUT A -IN A +IN A 1 2 3 8 7 6 5 SO-8 / MSOP-8 +VS OUT B -IN B +IN B +IN A +VS +INB -INB OUT B NC 14 +IND 13 -VS 12 +INC 11 10 9 -INC OUT C NC -VS 4 TSSOP-16 / SO-16 Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com REV.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION This integrated circuit can be damaged by ESD. Shengbang Micro-electronics recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ３ SGM8621/2/3 /4 TYPICAL PERFORMANCE CHARACTERISTICS (At TA = +25℃,VCM = Vs/2, RL = 600Ω, unless otherwise noted) Closed-Loop Output Voltage Swing 6 5 Output Voltage(Vp-p) 4 Vs = 5V VIN = 4.9VP-P TA = 25℃ RL = 10KΩ G=1 140 120 Output Impedance(Ω) 100 80 60 40 20 0 G = 100 G = 10 G =1 Vs = 5V Output Impedance vs.Frequency 3 www.DataSheet4U.com 2 1 0 10 100 1000 Frequency(kHz) 10000 0.1 1 10 100 Frequency(kHz) 1000 10000 Positive Overload Recovery Vs = ±2.5V VIN = 50mV RL = 620Ω G = 100 2.5V 0V 0V -50mV 0V 0V -50mV 2.5V Negative Overload Recovery Vs = ±2.5V VIN = 50mV RL = 620Ω G = 100 Time(5µs/div) Time(1µs/div) Large-Signal Step Response Vs = 5V G = +1 CL = 100pF RL = 620Ω Voltage(50mV/div) Voltage(1V/div) Small-Signal Step Response Vs = 5V G = +1 CL = 100pF RL = 620Ω Time(100µs/div) Time(100µs/div) ４ SGM8621/2/3 /4 TYPICAL PERFORMANCE CHARACTERISTICS (At TA = +25℃,VCM = Vs/2, RL = 600Ω, unless otherwise noted) PSRR vs.Frequency 120 Vs = 5V 100 80 CMRR vs.Frequency 110 100 90 80 CMRR(dB) Vs = 5V PSRR(dB) 70 60 50 www.DataSheet4U.com 60 40 20 1 10 100 Frequency(kHz) 1000 40 30 20 0.01 0.1 1 10 Frequency(kHz) 100 1000 Small-Signal Overshoot vs.Load Capacitance 70 Small-Signal Overshoot(%) 60 50 40 30 20 10 0 1 10 100 1000 Load Capacitance(pF) 10000 Vs = 5V RL = 10kΩ TA = 25℃ G=1 +OS -OS Channel Separation vs.Frequency 140 130 Channel Separation(dB) 120 110 100 90 80 0.1 1 10 Frequency(kHz) 100 1000 Vs = 5V RL = 620Ω TA = 25℃ G=1 CMRR vs.Temperature 120 110 100 CMRR(dB) 90 80 70 60 -50 -30 -10 10 30 50 70 Temperature(℃) 90 110 130 VCM = - 0.1V to 5.6V PSRR(dB) 120 PSRR vs.Temperature VS = 5.5V VCM = - 0.1V to 4 V 110 100 90 80 70 60 -50 -30 -10 VS = 2.5V to 5.5V 10 30 50 70 Temperature(℃) 90 110 130 ５ SGM8621/2/3 /4 TYPICAL PERFORMANCE CHARACTERISTICS (At TA = +25℃,VCM = Vs/2, RL = 600Ω, unless otherwise noted) Open-Loop Gain vs.Temperature 120 RL = 10KΩ Open–Loop Gain(dB) 110 Supply Current(μA) 300 275 250 225 200 175 350 325 Supply Current vs.Temperature 100 90 80 70 -50 -30 -10 10 30 50 70 90 110 130 Temperature(℃) RL = 600Ω www.DataSheet4U.com VS = 2.5V VS = 3V VS = 5V 150 -50 -30 -10 10 30 50 70 Temperature(℃) 90 110 130 Shutdown Current vs.Temperature 210 180 Shutdown Current(nA) 150 120 VS = 3V 90 60 VS = 2.5V 30 0 -50 -30 -10 10 30 50 70 Temperature(℃) 90 110 130 VS = 5V Output Voltage(V) 5 4 Output Voltage Swing vs.Output Current Sourcing Current 135℃ 3 VS = 5V 2 135℃ 1 25℃ 25℃ -50℃ -50℃ Sinking Current 0 0 10 20 30 40 50 O
