General Description
The EL6262C consists of 4 20MHz trans-impedance amplifiers and 4
70MHz trans-impedance amplifiers. The four 70MHz amplifier out-
puts also are averaged to provide differential 70MHz outputs.
The EL6262C 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 ampli-
fiers. The gain settings are 8K
, 15K, and 40K for all channels.
The sum and sumbar outputs are 11K
, 20K, and 45K single
ended. 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.
The E, F, G, and H channel bandwidths are 20MHz for all gains and
reasonable input and output loads. The A, B, C, D, S, and S channels
have bandwidths of 70MHz, 46MHz, and 32MHz at low, middle, and
high gains respectively after driving 25cm of flex circuit.
Each amplifier output can typically sink or source up to 5mA and their
outputs can swing 1VP-P at full bandwidth.
The EL6262C operates from a single +5V supply and is available in
QSOP-24 package. It is specified for operation from -0
°C to 70°C.
