Description
TZA1000
Input for fast reader/writer (track height servo) signal selection
Power fail detection on both 5 and 12 V lines (status can be read from the read register)
Write unsafe detection
Provides an accurate reference voltage (for AD conversion)
Very simple interconnection with the SZA1000 QIC digital equalizer
+5 V ±10% and +12 V ±10% supply voltages
Low power standby, active and test modes.
