The CA3160A and CA3160 are integrated circuit operational amplifiers that combine the advantage of both CMOS and bipolar transistors on a monolithic chip. The CA3160 series are frequency compensated versions of the popular CA3130 series.

Features

• MOSFET Input Stage Provides:

- Very High ZI= 1.5TΩ(1.5 x 1012Ω) (Typ)
