... Detailed Description Rail-to-Rail Input Stage The MAX4230–MAX4234 CMOS operational amplifiers have parallel-connected n- and p-channel differential input stages that combine to accept a common-mode range extending to both supply rails. The n-channel stage is active for common-mode input voltages typi- cally greater than ( ...

... For a 32Ω load, a 100µF aluminum electrolytic capaci- tor gives a low-frequency pole at 50Hz. Bridge Amplifier The circuit shown in Figure 3 uses a dual MAX4230 to implement a 3V, 200mW amplifier suitable for use in size-constrained applications. This configuration elimi- nates the need for the large coupling capacitor required by the single op-amp speaker driver when sin- gle-supply operation is necessary ...

... SHDN2 µMAX B Power Supplies and Layout The MAX4230–MAX4234 can operate from a single 2.7V to 5.5V supply, or from dual ±1.35V to ±2.5V sup- plies. For single-supply operation, bypass the power supply with a 0.1µF ceramic capacitor. For dual-supply operation, bypass each supply to ground. Good layout improves performance by decreasing the amount of stray capacitance at the op amps’ ...
