FEATURES

DESCRIPTION

The LD511 is a Class A compression amplifier which can

operate over a range of DC battery voltages from 1.1 V

to 2.4 V. A voltage regulator, which is independent of supply

voltage variations, is on-chip to supply a stable 0.94 VDC bias

to the amplifier circuitry and to the microphone.

• 64 dB typical electrical gain

• 0.94 VDC voltage regulator

• 7 ms attack time, 40 ms release time

• 15 dB threshold adjustment

• low noise and distortion

The LD511, in compression, has approximately 15 dB of

threshold adjustment by varying R_TH(see application circuit)

and a compression function ratio of ∞ : 1.

• compression ratio ∞ : 1

• 0.3 kHz - 6 kHz frequency response

Minimumattackandreleasetimesarefixedat 7msand40ms

respectively and they can be adjusted simultaneously by

changing the filter capacitor on pin 8, although the ratio of

attack to release time is kept constant.

STANDARD PACKAGING

• 10 pin MICROpac

• 10 pin MINIpac

• 10 pin PLID ^®

• 10 pin SLT

The output stage bias can be set to accommodate different

receiver impedances by changing the value of R_E. The

voltage across R_E(pin 2 to ground) is a constant 27 mV so the

bias current is 27 mV divided by the total value of R_Ein parallel

with 500 Ω.
