ISD1800 SERIES

PIN NAME

PIN NO.

I/O

FUNCTION

MIC

Microphone Input: The microphone input

transfers its signals to the on-chip preamplifier. An

on-chip Automatic Gain Control (AGC) circuit

controls the gain of the preamplifier. An external

microphone should be AC coupled to this pin via

a series capacitor. The capacitor value, together

with an internal 10 Kꢀ resistance on this pin,

determines the low-frequency cutoff for the I1800

passband.

MIC REF

AGC

Microphone Reference: The MIC REF input is

the inverting input to the microphone preamplifier.

This provides input noise-cancellation, or

common-mode rejection, when the microphone is

connected differentially to the device.

Automatic Gain Control: The AGC dynamically

adjusts the gain of the preamplifier to compensate

for the wide range of microphone input levels. The

AGC allows the full range of sound, from whispers

to loud sounds, to be recorded with minimal

distortion. Nominal values of 4.7 µF give

satisfactory results in most cases.

Connecting this pin to ground (V_SSA) provides

maximum gain to the preamplifier circuitry.

Conversely, connecting this pin to the power

supply (V_CCA) provides minimum gain to the

preamplifier circuitry.

SP-/SP+

15, 17

Speaker Outputs: The SP+ and SP- pins provide

direct drive for loudspeakers with impedances as

low as 8ꢀ. A single output may be used, but, for

direct-drive loud-speakers, the two opposite-

polarity outputs provide an improvement in output

power of up to four times over a single-ended

connection. Furthermore, when SP+ and SP- are

used, a speaker coupling capacitor is not

required. A single-ended connection will require

an AC-coupling capacitor between the SP pin and

the speaker.

The SP+ pin and the SP- pin are internally

connected through a 50 Kꢀ resistance. When not

in playback mode, they are floating.
