Low Current Preamplifier

with Output Limiting

GL504 - DATA SHEET

DESCRIPTION

FEATURES

The GL504 is a low current preamplifier designed to drive

the class D series of integrated receivers. This preamp has a

built-in symmetrical peak clipping output limiter, 46 dB of

adjustable gain, and requires few external components.

• designed to drive class D integrated receivers

• MPO range externally adjustable

• 150 µA typical current drain

• 46 dB of adjustable gain

Composed of two stages, an inverting preamp with gain of

28 dB, and a transconductance block with gain of 18 dB, the

GL504 is easily configured for mid-supply reference as

required by the class D receivers.

• low external parts count

STANDARD PACKAGING

• 8 Pin MICROpac

• 8 Pin PLID^®

• 8 Pin SLT

The two stages of the GL504 must be AC coupled in order to

maintain the DC bias conditions of each stage. Also, a 48

kΩ resistor, between the output and ground, is used to keep

the receivers at mid-supply reference. The minimal total parts

count, excluding an MPO variable resistor, requires 3

capacitors, a 100 kΩ volume control and the 48 kΩ bias

resistor at the output.

• Chip (56 x 56 mils)

Au Bump

The GL504 is capable of providing a flat frequency response

with very little distortion.
