General Description The MAX4493/MAX4494/MAX4495 single/dual/quad general-purpose operational amplifiers are designed for use in systems powered with dual supplies from ±2.25V to ±5.5V or with a single supply of +4.5V to +11V. These op amps provide a unity-gain bandwidth of 5MHz with only 770µA of quiescent current per amplifier. The wide input common-mode range extends from 200mV beyond the negative rail to within 1.5V of the positive supply rail while the output swings within 10mV (RL = 100kΩ) of either rail. These amplifiers have excellent (110dB) open-loop gain with very low THD+N of 0.002% (f = 1kHz). The single MAX4493 is available in a tiny 5-pin SC70 pack- age and the dual MAX4494 is available in the space- saving 8-pin SOT23. The quad MAX4495 is available in both 14-pin TSSOP and 14-pin SO packages. All prod- ucts are rated at the automotive temperature range of -40°C to +125°C. ________________________Applications Battery-Powered Systems DAC Output Amplifiers Industrial Control Systems Voltage Reference Generators Signal Conditioning Features  770µA Supply Current per Amplifier  Operates from Dual ±2.25V to ±5.5V Supplies  5MHz Gain-Bandwidth Product  Rail-to-Rail Output Swing  Input Voltage Range Extends 200mV Below the Negative Rail  110dB Open-Loop Gain (RL = 100kΩ)  Low THD+N of 0.002% (f = 1kHz)  No Phase Reversal for Overdriven Inputs  Unity-Gain Stable  Available in Space-Saving Packages 5-Pin SC70 (MAX4493) 8-Pin SOT23 (MAX4494) 14-Pin TSSOP (MAX4495) M A X 4 4 9 3 /M A X 4 4 9 4 /M A X 4 4 9 5 SC70, Low-Power, General-Purpose, Dual-Supply, Rail-to-Rail Op Amps ________________________________________________________________ Maxim Integrated Products 1 VEE OUTIN- 1 + 5 VCCIN+ MAX4493 SC70/SOT23-5 TOP VIEW 2 3 4 Pin Configurations 19-1797; Rev 3; 12/09 Ordering Information Pin Configurations continued at end of data sheet.

Capacitive-Load Stability Driving large capacitive loads can cause instability in many op amps. The MAX4493/MAX4494/MAX4495 are stable with capacitive loads up to 300pF. The Capacitive-Load Stabil i ty graph in the Typical Operating Characteristics gives the stable operation region for capacitive versus resistive load. Stability with higher capacitive loads can be improved by adding an isolation resistor in series with the op-amp output, as shown in Figure 1. This resistor improves the circuit’s phase margin by isolating the load capacitor from the amplifier’s output. As seen in the Typical Operating Characteristics, driving capacitive loads with an isola- tion resistor exhibits some overshoot, but no oscillation.

Power-Up Conditions The MAX4493/MAX4494/MAX4495 typically settle within 3µs after power-up. See Power-Up Time in Typical Operating Characteristics. Power Supplies and Layout The MAX4493/MAX4494/MAX4495 operate with dual supplies from ±2.25V to ±5.5V. Bypass both VCC and VEE with their own 0.1µF capacitor to ground. Good layout technique helps optimize performance by decreasing the amount of stray capacitance at the op amp’s inputs and outputs. To decrease stray capaci- tance, minimize trace lengths by placing external com- ponents close to the op amp’s pins.
