The SSI 32R2214RX is a BiCMOS monolithic integrated circuit designed for use with two-terminal recording heads. It provides a low noise read amplifier, write current control, and data protection circuitry for up to four channels. The SSI 32R2214RX has an internal 900Ω damping resistor. The damping resistor is switched in during write mode and switched out du.
