Precision front-end for sensor and industrial signal chains
The LMR1801HFV-LBTR is a single-channel CMOS operational amplifier from ROHM's LMR series, offering 6 MHz gain-bandwidth product with a 5 µV typical input offset — low enough to skip external nulling in most DC-coupled precision stages. Rail-to-rail output swing at a minimum supply of 2.2 V (max 5.5 V) allows the amplifier to use the full ADC input range in low-voltage mixed-signal designs, common in battery-powered field transmitters and portable instrumentation.
A 2.5 V/µs slew rate combined with 6 MHz GBW supports full-power bandwidth up to roughly 400 kHz at 2 Vpp output — sufficient for audio-band anti-aliasing filters, motor-current sense amplifiers, and general-purpose control loops without slew-induced distortion.
Housed in a SOT-665 package (supplier device package 5-HVSOF), the LMR1801HFV-LBTR occupies minimal PCB area — the 5-pin footprint is suitable for space-constrained multi-channel arrays or handheld devices.
ROHS3 compliant, the part meets the latest EU restriction standards, simplifying BOM acceptance across global markets.
