32R2214RX
DESCRIPTION
The SSI 32R2214RX is a Bi CMOS 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 during read mode. Power supply fault protection is provided by disabling the write current generator during power sequencing. System write to read recovery time is significantly improved by making the read channel outputs high impedance. Two guard pins are provided for maximum supply noise rejection. The device also offers multiple channel “servo bank write” capability to assist in servo writing operations. The SSI 32R2214RX requires only a +5V power supply.
