4-channel Low Power Preamplifier

The L6316 is a BICMOS Silicon Germanium inte- grated circuit differential preamplifier. It is de- signed for use with four-terminal MR read and in- ductive write heads. In read mode, the device consists of a fully Differential Amplifier offering; voltage or current bias, voltage-sense input, pro- grammable input impedance, low noise and high bandwidth. In write mode, it includes fast current switching differential write drivers, which support data rates up to 1200 Mb/s. This preamplifier provides programmable read voltage or current bias and write current (5 bit DACs for the read bias and for the write current), fault detection circuitry and servo track writing fea- tures. Read Amplifier gain, low corner frequency, and write current wave shape are adjustable. The amplitude and duration of the overshoot are sepa- rately programmable through a 16-bit bi-direction- al serial Interface (SEN, SDATA, and SCLK). The device operates from +5V and -3V supplies.
