V/F and F/V Converters

LM2907MX-8 Description

The LM2907MX-8 from Texas Instruments is a precision frequency-to-voltage converter designed for surface-mount applications. Packaged in an 8-SOIC and supplied in Tape & Reel (TR), this IC offers a highly linear (±0.3%) conversion of input frequency (up to 10 kHz) to a proportional output voltage. With an ECCN of EAR99 and REACH Unaffected status, it complies with global regulatory standards. Though marked Obsolete, its robust performance and reliability make it suitable for legacy or low-volume designs. The device operates with a Moisture Sensitivity Level (MSL) of 1 (Unlimited), ensuring ease of handling in manufacturing environments.
