SSI32R2214RX Datasheet

SSI32R2214RX 4-Channel Thin Film Read/Write Device

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 r.
