Description
TZA1015
The TZA1015 is a data amplifier and laser supply circuit for 3-beam pick-up detectors found in a wide range of CD and read-only optical systems.The device contains 6 transimpedance amplifiers to amplify and filter the focus and radial photo diode voltage input signals.The preamplifier forms a versatile, programmable interface from voltage output CD mechanisms to the Philips’ digital signal processor family.The dynamic range of this preamplifier/processor combination can be optimized
Features
- Six input buffer amplifiers with low-pass filtering and virtually no offset.
 
- Universal photodiode IC interface using internal conversion resistors.
 
- RF data amplifier with wide bandwidth designed for data rates up to a maximum of 30Ă—.
 
- Programmable RF gain for CD-A/V, CD-R, CD-R/W and CD-ROM.
