SGM8061 SGM8062 SGM8063 PRODUCT DESCRIPTION The SGM8061, SGM8062, SGM8063 are rail-to-rail output voltage feedback amplifiers offering ease of use and low cost. They have bandwidth and slew rate typically found in current feedback amplifiers. All have a wide input common-mode voltage range and output voltage swing, making them easy to use on single supplies as low as 2.5 V. Despite being low cost, the SGM8061 series provide excellent overall performance. they offer wide bandwidth to 500 MHz (G = +1) along with 0.1 dB flatness out to 130 MHz (G = +1) and offer a typical low power of 8.2 mA/amplifier. The SGM8061 series is low distortion and fast settling make it ideal for buffering high speed A/D or D/A converters. The SGM8063 has a power-down disable feature that reduces the supply current to 75µA. These features make the SGM8063 ideal for portable and battery-powered applications where size and power are critical. All are specified over the extended –40°C to +125°C temperature range. 500MHz, Rail-to-Rail Output CMOS Operational Amplifier FEATURES • Low Cost • Rail-to-Rail Output 2mV Typical VOS • High Speed 500 MHz, –3 dB Bandwidth (G = +1) 420 V/µs, Slew Rate 16 ns Settling Time to 0.1% with 2V Step • Operates on 2.5 V to 5.5V Supplies • Input Voltage Range = – 0.2 V to + 3.8 V with VS = 5V • Excellent Video Specs (RL = 150Ω, G = +2) Gain Flatness 0.1dB to 80 MHz Diff Gain: 0.015 %, Diff Phase: 0.05 degree • Low Power 8.2 mA/Amplifier Typical Supply Current SGM8063 75µA when Disabled • Small Packaging SGM8061 Available in SO-8 and SOT23-5 SGM8062 Available in SO-8 SGM8063 Available in SO-8 and SOT23-6 APPLICATIONS Imaging Photodiode Preamp Professional Video and Cameras Hand Sets DVD/CD Base Stations Filters A-to-D Driver Non-Inverting Small Signal Frequency Response 3 Vo = 0.1VP-P 0 Normalized Gain(dB) -3 -6 -9 -12 -15 1 10 100 Frequency(MHz) 1000 G = +2 G = +5 G = +10 RF = 24Ω G = +1 PIN CONFIGURATIONS (Top View) SGM8061 VOUT -VS 1 2 4 -IN 5 +VS VOUT1 1 -IN1 2 +IN1 3 -VS 4 SGM8062 8 7 6 5 +VS VOUT2 -IN2 +IN2 +IN 3 SOT23-5 SO-8 SGM8061/8063 NC -IN +IN -VS 1 2 3 4 8 7 6 5 DISABLE (SGM8063 ONLY) +VS VOUT NC +IN VOUT -VS 1 2 3 SGM8063 8063 6 5 4 +VS DISABLE -IN SO-8 NC = NO CONNECT SOT23-6 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 SGM8061/2/3 TYPICAL PERFORMANCE CHARACTERISTICS At TA = +25℃, VS = +5V, G = +2, RF = 402Ω, RG = 402Ω, and RL=150Ω connected to Vs/2,unless otherwise noted.

Output capacitance will create a pole in the amplifier’s feedback path, leading to excessive peaking and potential oscillation. If dealing with load capacitance is a requirement of the application, the two strategies to consider are (1) using a small resistor in series with the amplifier’s output and the load capacitance and (2) reducing the bandwidth of the amplifier’s feedback loop by increasing the overall noise gain. Figure 1 shows a unity gain follower using the series resistor strategy. The resistor isolates the output from the capacitance and, more importantly, creates a zero in the feedback path that compensates for the pole created by the output capacitance.

Amplifier with Bypass Capacitors RISO SGM8061 VIN VOUT CLOAD Grounding A ground plane layer is important for high speed circuit design. The length of the current path speed currents in an inductive ground return will create an unwanted voltage noise. Broad ground plane areas will reduce the parasitic inductance. Figure 1. Series Resistor Isolating Capacitive Load Power-Supply Bypassing and Layout The SGM806x family operates from either a single +2.7V to +5.5V supply or dual ±1.35V to ±2.75V supplies. For single-supply operation, bypass the power supply VDD with a 0.1µF ceramic capacitor which should be placed close to the VDD pin. For dual-supply operation, both the VDD and the VSS supplies should be bypassed to ground with separate 0.1µF ceramic capacitors. 2.2µF tantalum capacitor can be added for better performance. Good PC board layout techniques optimize performance by decreasing the amount of stray capacitance at the op amp’s inputs and output. To decrease stray capacitance, minimize trace lengths and widths by placing external components as close to the device as possible. Use surface-mount components whenever possible. For the high speed operational amplifier, soldering the part to the board directly is strongly recommended. Try to keep the high frequency big current loop area small to minimize the EMI (electromagnetic interfacing). Input-to-Output Coupling To minimize capacitive coupling, the input and output signal traces should not be parallel. This helps reduce unwanted positive feedback. ９ SGM8061/2/3 Typical Application Circuits Differential Amplifier The circuit shown in Figure 3 performs the difference function. If the resistors ratios are equal ( R4 / R3 = R2 / R1 ), then VOUT = ( Vp – Vn ) × R2 / R1 + Vref. Driving Video The SGM806x can be used in video applications like in Figure 5.

Typical Video Driving Low Pass Active Filter The low pass filter shown in Figure 4 has a DC gain of ( - R2 / R1 ) and the –3dB corner frequency is 1/2πR2C. Make sure the filter is within the bandwidth of the amplifier. The Large values of feedback resistors can couple with parasitic capacitance and cause undesired effects such as ringing or oscillation in high-speed amplifiers. Keep resistors value as low as possible and consistent with output loading consideration. C R2 VIN R1 VOUT SGM8061 R3 = R1 // R2 Figure 4.
