The TLS21H62-3PW monolithic preamplifier is designed for two-terminal thin-film or metal-in-gap (MIG) recording heads. The preamplifier incorporates data-protection circuitry for both channels and features low-noise read paths and write-current controls. When deactivated, the preamplifier enters an idle mode that reduces power dissipation to 0.5 mW, typically. The write-current generator is disabled during power sequencing to provide power-supply fault protection.
During write and idle modes, the differential read-data (RDX and RDY) lines are placed in the high-impedance state to improve system write-to-read and idle-to-read recovery times. Isolated damping resistors effectively switch out the resistance during read operations.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to GND.
