TZA1000
FEATURES
- 3-wire serial interface for programming
- On-chip Digital-to-Analog Converters (DAC) for:
- MR (Magneto Resistive) sense bias current
- MR DC bias current
- Write current
- Low noise differential input stage: typically 0.65 n V/√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 m A: ready for high coercivity tape
- Low noise read amplifier for reading track height servo signals with the write coil
- Very few external ponents required
- On board registers for easy format or bit rate selection
- Fast read-after-write recovery time
- Test circuit for yoke-type heads
- Switchable differentiator for yoke-type heads, with programmable cut-off frequencies
- Anti-aliasing low-pass filter, with programmable cut-off frequencies
- AGC (Automatic Gain Control) options: internally (digitally) controlled, externally controlled...
