EL6262C - Product Brief

Quad 20MHz & Quad, 70MHz, Switched Gain Pre-Amp

Features

General Description

• Autozero of output offset to

<10mV

• 3 selectable gains; 8KW, 15KW,

40KW

• Space saving QSOP-24 package

• Differential Sum & Sum-Bar

outputs

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 8KW, 15KW, and 40KW for all channels.

The sum and sumbar outputs are 11KW, 20KW, and 45KW 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.

• Single 5V supply

Applications

• DVD RAM, RW, and ROM

• CD RW, R and ROM

• MO drives

• Optical Pickup pre-amplifier

• Servo positioning systems

• High speed instrumentation

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 1V_P-Pat full bandwidth.

Ordering Information

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.
