These devices require only 900µA per amplifier, and operate from either a single supply (+2.7V to +6.5V) or dual supplies (±1.35V to ±3.25V) with a common-mode voltage range that extends 250mV beyond VEE and VCC. They are capable of driving 250Ω loads and are unity-gain stable. In addition, the MAX4131/ MAX4133 feature a shutdown mode in which the outputs are placed in a high-impedance state and the supply current is reduced to only 25µA per amplifier. With their rail-to-rail input common-mode range and output swing, the MAX4130–MAX4134 are ideal for lowvoltage, single-supply operation. Although the minimum operating voltage is specified at 2.7V, the devices typically operate down to 1.8V. In addition, low offset voltage and high speed make them the ideal signalconditioning stages for precision, low-voltage dataacquisition systems. The MAX4130 is offered in the space-saving 5-pin SOT23 package. The MAX4131 is offered in the ultra-small 6-bump, 1mm x 1.5mm chipscale package (UCSP™). MAX4130–MAX4134 Single/Dual/Quad, Wide-Bandwidth, Low-Power, Single-Supply Rail-to-Rail I/O Op Amps ABSOLUTE MAXIMUM RATINGS Supply Voltage (VCC - VEE) ...................................................7.5V IN+, IN-, SHDN Voltage ...................(VCC + 0.3V) to (VEE - 0.3V) Output Short-Circuit Duration (Note 1).......................Continuous (short to either supply) Continuous Power Dissipation (TA = +70°C) 5-Pin SOT23 (derate 7.1mW/°C above +70°C)............571mW 6-Bump UCSP (derate 2.9mW/°C above +70°C).........308mW 8-Pin SO (derate 5.88mW/°C above +70°C)................471mW 8-Pin µMAX (derate 4.10mW/°C above +70°C) ...........330mW 14-Pin SO (derate 8.00mW/°C above +70°C)..............640mW Operating Temperature Range MAX413_E__ ...................................................-40°C to +85°C Maximum Junction Temperature .....................................+150°C Storage Temperature Range .............................-65°C to +160°C Lead Temperature (soldering, 10s) .................................+300°C Bump Reflow Temperature .........................................+235°C Note 1: Provided that the maximum package power-dissipation rating is not exceeded.

The input stage consists of separate NPN and PNP differential stages that combine to provide an input common-mode range that extends 0.2V beyond the supply rails. The PNP stage is active for input voltages close to the negative rail, and the NPN stage is active for input voltages near the positive rail. The input offset voltage is typically below 200µV. The switchover transition region, which occurs near VCC / 2, has been extended to minimize the slight degradation in common-mode rejection ratio caused by the mismatch of the input pairs. Their low offset voltage, high bandwidth, and rail-to-rail common-mode range make these op amps excellent choices for precision, low-voltage data-acquisition systems. Since the input stage switches between the NPN and PNP pairs, the input bias current changes polarity as the input voltage passes through the transition region. Reduce the offset error caused by input bias currents flowing through external source impedances by matching the effective impedance seen by each input (Figures 1a, 1b). High source impedances, together with input capacitance, can create a parasitic pole that produces an underdamped signal response. Reducing the input impedance or placing a small (2pF to 10pF) capacitor across the feedback resistor improves response. The MAX4130–MAX4134s’ inputs are protected from large differential input voltages by 1kΩ series resistors and back-to-back triple diodes across the inputs (Figure 2). For differential input voltages less than 1.8V, input resistance is typically 500kΩ. For differential input voltages greater than 1.8V, input resistance is approximately 2kΩ. The input bias current is given by the following equation: IBIAS = VDIFF - 1.8V 2kΩ 1kΩ 1kΩ Figure 2.

The MAX4130–MAX4134 have a high tolerance for capacitive loads. They are stable with capacitive loads up to 160pF. Figure 4 gives the stable operating region for capacitive loads. Figures 5 and 6 show the response with capacitive loads and the results of adding an isolation resistor in series with the output (Figure 7). The resistor improves the circuit’s phase margin by isolating the load capacitor from the op amp’s output. 500 450 LOAD CAPACITANCE (pF) VOLTAGE (1V/div) VCC = 3V, RL = 10kΩ to VEE IN 400 UNSTABLE OPERATING REGION 350 300 250 200 150 STABLE OPERATING REGION 100 OUT RL TO VEE VOUT = VCC/2 50 0 TIME (1µs/div) 0.1 1 10 100 LOAD RESISTANCE (kΩ) Figure 4.

Figure 3 shows the input voltage range and output voltage swing of a MAX4131 connected as a voltage follower. With a +3V supply and the load tied to ground, the output swings from 0.00V to 2.90V. The maximum output voltage swing depends on the load, but will be within 150mV of a +3V supply, even with the maximum load (500Ω to ground). Power-Up and Shutdown Mode The MAX4130–MAX4134 amplifiers typically settle within 1µs after power-up. Figures 9 and 10 show the output voltage and supply current on power-up, using the test circuit of Figure 8. The MAX4131 and MAX4133 have a shutdown option. When the shutdown pin (SHDN) is pulled low, the supply current drops below 25µA per amplifier and the amplifiers are disabled with the outputs in a highimpedance state. Pulling SHDN high or leaving it floating enables the amplifier. In the dual-amplifier MAX4133, the shutdown functions operate independently. Figures 11 and 12 show the output voltage and supply current responses of the MAX4131 to a shutdown pulse, using the test circuit of Figure 8.

Shutdown Output Voltage Power Supplies and Layout The MAX4130–MAX4134 operate from a single +2.7V to +6.5V power supply, or from dual supplies of ±1.35V to ±3.25V. For single-supply operation, bypass the power supply with a 0.1µF ceramic capacitor in parallel with at least 1µF. For dual supplies, bypass each supply to ground. Good layout improves performance by decreasing the amount of stray capacitance at the op amp’s inputs and outputs. Decrease stray capacitance by placing external components close to the op amp’s pins, minimizing trace lengths and resistor leads. TIME (1µs/div) Figure 12.
