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. Supply span runs from 2.7 V to 5.5 V. Each of the four amplifiers draws 1.2 mA total supply current. The input bias current is 1 pA. 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 operating temperature range of -40°C to 125°C covers industrial process control, automotive under-hood modules, and outdoor telecom equipment. 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.
Sourcing and lifecycle — no LTB risk, active production
The MAX4234AUD+T carries an Active product status and is ROHS3 compliant. There is no last-time-buy notice or end-of-life signal on this part. For a BOM line that needs a quad CMOS op-amp with rail-to-rail output and high output drive, this part is a safe commit for new designs and production builds.
