TZA1000 Key Features
- 3-wire serial interface for programming
- MR (Magneto Resistive) sense bias current
- MR DC bias current
- Write current
- Low noise differential input stage: typically 0.65 nV/√Hz (Zi = 0 Ω)
- Magnetic feedback circuit to handle large output signals
- MR DC bias current circuit
- Very fast write current rise and fall times with near rail-to-rail voltage swing
- Maximum write current of 100 mA: ready for high coercivity tape
- Low noise read amplifier for reading track height servo signals with the write coil
