Integrated Circuit
DC–Coupled Vertical Deflection Circuit
Description:
The NTE7131 is an integrated circuit in a 9–Lead SIP type package designed for use in 90° and 110°
color deflection systems for field frequencies of 50 to 120Hz. The circuit provides a DC driven vertical
deflection output circuit, operating as a highly efficient class G system.
