4.5. External Current Limit - Peak (ECLP)

The peak current limit of the Flute amplifier can be scaled down by an external voltage or by an

external resistor connected between pin J2/3 (ECLP) and pin J2/2 (ECLRET).

4.5.1. External Voltage

An external positive voltage (0 to 3.75 V) to terminal J2/3 (ECLP) in reference to terminal J2/2

(ECLRET) will control the peak current limit from zero to Ip(nom).

• The voltage is internally clamped to 3.75 V whenever the external V

ECLP

is higher than

3.75 V.

• The external voltage source must be able to source/sink at least ±0.4 mA.

• The maximum absolute V

ECLP

is 12 V.

4.5.2. External Resistor

Connect an external resistor between terminal J2/3 (ECLP) and terminal J2/2 (ECLRET). The

resistor value is given by:

(Kohm) = 12.5 *

< 11.4 K (1/8 Watt)

• At R

greater than 11.4K, the current limit will be internally clamped to the nominal

value.

• I

is the nominal peak current limit of the amplifier.
