CXA1829N Description
The CXA1829N is a Read/Write amplifier for hard disk drive thin-film heads and is designed to handle up to 8-channel heads.
CXA1829N Key Features
- Operates on a single 5V power supply
- Low power consumption. Read: 115 mW Write (IW = 15 mA): 160 mW + IW × 5 Power Save: 7 mW
- Write current can be varied through an external resistor. Built-in stabilizer circuit provides stable current, preventin
- Drives up to 8 heads
- Supports thin film heads or 2-pin MIG heads
- Emitter follower-type Read amplifier features 290 times gain (typ.)
- Write-unsafe detection circuit
- Damping resistance is switched at Write (315 Ω)
- Simultaneous Write function
- Supply voltage monitor circuit prohibits error writing during power surge or abnormal voltage
