FEATURES

DESCRIPTION

The LC/LV/LD549 is an 8 pin, low voltage, push-pull audio

frequency output stage amplifier with a single unbalanced

input. The circuit utilizes two internal negative feedback

loops to stabilize the DC operating point for temperature

stability and to linearize the transfer function over a wide

dynamic range. The circuit operates near ideal class B

conditions resulting in low distortion and very low quiescent

current, required for extended battery life.

• 40dB of electrical gain

• 1.0 to 1.6 VDC supply operating range

• current trim capability (R_T)

• high efficiency class B output stage

• may be used with a linear or compression preamplfier

STANDARD PACKAGING

The LC549, LV549 and LD549 differ in only one respect;

the LV549 and LD549 are selected devices which are

capable of delivering from 10 mA to 41 mA and from 36 mA

to 75 mA of output current respectively. These values are

themaximumcurrentdrawnwithbothoutputstagetransistors

in saturation. Thus the LD549 is capable of producing a

high output in a low impedance load, the LV549 is selected

to have lower peak currents, extending the life of the

battery.

• 8 pin MICROpac (LC549)

• 8 pin MINIpac

• 8 pin PLID^®(LC549, LD549)

• Chip (47 x 40 mils) (LC549, LD549)
