Frequency-to-voltage conversion up to 10 kHz
The LM2907M-8/NOPB is a frequency-to-voltage converter from Texas Instruments, handling input frequencies up to 10 kHz with a linearity of ±0.3%. This makes it a fit for tachometer inputs, speed sensing, or any application where a variable-frequency signal needs to be translated to a proportional DC voltage for an ADC or comparator input.
8-SOIC package — rework and layout notes
The 1.27 mm pitch gives good visual access for inspection and hand rework — a hot-air station can lift this without cooking adjacent passives, provided the ground pad isn't oversized. Pin 1 is clearly marked on the package top, so orientation is unambiguous under a scope.
