General Description
The EL6261C consists of 4 20MHz trans-impedance amplifiers and 4
80MHz trans-impedance amplifiers. The four 80Mhz amplifier out-
puts also are averaged to provide differential 80MHz outputs.
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 ampli-
fiers. The gain settings are 8K
, 15K and 40K for all channels.
The sum and sumbar outputs are 11K
, 20K and 53K 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,H channel bandwidths are 20MHz for all gains and reason-
able input and output loads. The A,B,C,D,S,S channels have
bandwiths of 80MHz, 45MHz, and 25MHz at low, middle, and high
gains respectively.
Each amplifier output can sink or source up to 5mA, and their outputs
can swing 1Vp-p at full bandwidth.
The EL6261C operates from a single +5V supply, and is available in
QSOP-24 package. It is specified for operation from -0
°C to 70°C
