Product details

2.3 MHz CMOS dual op amp — what it buys the signal chain

The ROHM TLR342F-GE2 is a dual CMOS operational amplifier with a 2.3 MHz gain-bandwidth product and a 1.2 V/µs slew rate, designed for general-purpose signal conditioning in battery-powered and industrial systems. Each channel draws 150 µA quiescent current, making it a fit for multi-channel sensor interfaces where power budgets are tight. The 1 pA input bias current suits high-impedance sources such as photodiode transimpedance amplifiers or pH electrode buffers without adding offset from source loading.

Package and temperature grade — board-fit and environment

Housed in an 8-SOIC (4.40 mm width) package, also designated 8-SOP, the TLR342F-GE2 uses a standard surface-mount footprint compatible with automated assembly and rework.

Sourcing and stock — where to buy TLR342F-GE2

For dual-sourcing flexibility, the pin-compatible TLR342FJ-GE2 offers identical 2.3 MHz GBW and 1.2 V/µs slew rate in the same 8-SOP package, making it a drop-in second source for supply resilience.

Frequently asked questions

What is the replacement or equivalent for TLR342F-GE2?

The TLR342FJ-GE2 is a pin-compatible second source with identical 2.3 MHz GBW, 1.2 V/µs slew rate, and 8-SOP package. No direct replacement is needed — both are active and available.

How does TLR342F-GE2 compare to other dual CMOS op amps?

Compared to the ROHM BU7262FVM-TR (2 MHz GBW, 1.1 V/µs slew rate), the TLR342F-GE2 offers slightly higher bandwidth and slew rate, making it a better fit for faster signal chains while maintaining similar 150 µA supply current.
