150 MHz GBW, 80 V/µs — signal-chain bandwidth ceiling
The LMR1701G-LBTR is a single-channel CMOS operational amplifier from ROHM's LMR series, offering a gain-bandwidth product of 150 MHz and a slew rate of 80 V/µs. For a closed-loop gain of 10, the small-signal bandwidth is approximately 15 MHz; the slew rate supports a full-scale 5 V output swing up to roughly 8 MHz before slew-induced distortion sets the limit. Output type is push-pull, rail-to-rail, with a rated output current of 200 mA per channel — sufficient to drive the input of a successive-approximation ADC directly or to charge a 100 pF load at the full slew rate without an external buffer. The CMOS input stage keeps the bias current low enough that a photodiode or high-impedance sensor front-end does not require a separate JFET buffer.
The quiescent current is 9.6 mA, which is moderate for a 150 MHz amplifier — the power budget should account for this in multi-channel arrays. No AEC-Q grade is stated in the record, so qualification for automotive use should be verified against the manufacturer's latest documentation.
SOT-23-6 package — board-fit and sourcing posture
Packaged in a 6-pin SOT-23-6 (supplier device package 6-SSOP), the LMR1701G-LBTR occupies approximately 3 mm × 3 mm of board area. The pin pitch is 0.95 mm, compatible with standard fine-pitch soldering profiles. Lifecycle status is Active per the manufacturer, with ROHS3 compliance (no exemptions expiring).
