LA7116 VCR Servo Interface IC DIP 24
The LA7116 VCR Servo Interface IC DIP 24 is a monolithic linear integrated circuit designed to implement the analog front-end for VCR servo control systems. It operates as an interface between frequency generator (FG) signals, pulse generator (PG) signals, and CTL head signals and the digital servo controller, such as the LC7412/LC7413, providing stable and accurate processing of timing information. By integrating multiple amplifier stages, Schmitt trigger comparators, and an operational amplifier section into a single device, the LA7116 enables cost-effective and compact servo system designs.
Features:
- Monolithic linear VCR servo interface IC for use with LC7412/LC7413 controllers.
- Integrated drum FG, capstan FG, CTL, and drum PG amplifier stages.
- CTL Schmitt trigger section with selectable threshold width for noise-optimized operation.
- Built-in reference voltage network for stable biasing of multiple internal stages.
- Operational amplifier section operable up to 12V for flexible analog signal conditioning.
