TZA1015 is a data amplifier and laser supply circuit for CD and read-only optical systems (HDALAS) from Philips Semiconductors. It features six input buffer amplifiers with low-pass filtering and virtually no offset. It also features a universal photodiode IC interface, wide bandwidth RF data amplifier, programmable RF gain, programmable RF bandwidth, radial error signal, programmable RF/Fast Track Count (FTC) gain, fully automatic laser control, automatic monitor diode polarity selection, adjustable laser bandwidth and laser switch-on current slope, supply voltage range, temperature range and low power consumption.
The TZA1015 is a data amplifier and laser supply circuit designed for 3‑beam pick‑up detectors used in CD and read‑only optical systems. It integrates six transimpedance amplifiers, programmable RF gain and bandwidth, and an automatic laser power control circuit.
The device is supplied in a 28‑lead plastic small‑outline package (SOT136‑1) and operates over a wide supply voltage (4.5‑5.5 V) and temperature range (0 °C to 85 °C). Detailed pin assignments, limiting values, and electrical characteristics are provided for system designers.
