General Description

The LD3301-1, LD3301-2 are BiCMOS devices that support a 1-channel (2-channel) GMR Preamplifier.

They are designed for use with 4-terminal magnetoresistive recording heads, providing a low noise GMR head amplifier, GMR bias current control, thin film write driver, write current control, thermal asperity detection and correction.

Fast recovery mode can be also programmed to put the chip faster in read mode from any other existing modes.

Key Features

  • and thresholds are controlled through a serial port interface. This product requires +3.3V or +5V supply voltage. Available in flip-chip or TSSOP packages. GMR resistor range: 25Ω to 65Ω Programmable 5 bit GMR head bias current: Ib = 2mA-9.75mA Programmable gain control: 130V/V & 200V/V @ Rmr = 35Ω, Ib = 6mA Wide bandwidth: BW = 250 MHz at -1dB @ Rmr = 35Ω Programmable booster for wide bandwidth Equivalent input noise: Vn = 0.8nV/√Hz @ Rmr = 35Ω Impedance matched differential inputs for WDX and.
