Quad CMOS op-amp with rail-to-rail output and high output drive
The MAX4234AUD+T is a quad CMOS op-amp with rail-to-rail output in a 14-TSSOP package. It has a 10 MHz gain-bandwidth product and 10V/µs slew rate. Each of the four amplifiers draws 1.2 mA total supply current. Output current is rated at 200 mA per channel — unusually high for a CMOS op-amp. That lets it drive a heavy load such as a headphone, a small solenoid, or a long twisted-pair cable without an external buffer stage. The rail-to-rail output swing preserves dynamic range when the supply is low. The 14-TSSOP footprint is a common land pattern, so a board designed for a generic quad op-amp in TSSOP-14 will accept this part with no layout change.
