The EL6261C is designed to amplify the photo diode currents for CD, DVD, or other photo diode pick-up applications. Two TTL/CMOS compatible inputs select the gain for all eight amplifiers. The gain settings are 8K, 15K and 40K for all channels. The sum and sumbar outputs are 11K , 20K a nd 53K single ended. Gain matching is typically 3%, channel to channel. An autozero input brought high after power up reduces the output offsets to less than 10mV.
