Description

   The EL6265C consists of 13 fast settling, switch gain, trans-impedance amplifiers with source terminated flex drive capability. The amplifier bandwidth and settling times varies with the selected gain.The fast channel bandwidths are 59MHz, 43MHz, and 34MHz. With a short flex, the bandwidths can be slightly increased.

   The EL6265C 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 EL6265C.The gain settings are 12kW, 23kW, and 63kW for all channels.Gain matching is typically 3%, channel to channel. An auto-zero input brought high after power up reduces the output offsets to less than 10mV.

   Each amplifier EL6265C output can typically sink or source up to 5mA and their outputs can swing 1VP-P at full bandwidth at the end of a long flex circuit. The EL6265C operates from a single +5V supply and is available in an LPP-38 package. It is specified for operation from -0°C to 70°C.
