4.2.2External Resistor

RECLC (Kohm) = 37.4 *

Ic(new)

- 1

Ic(nom)

 

 

Connect an external resistor between terminal J1/9 (ECLC) and terminal J1/8 (ECLRET). The resistor value is given by:

0 < RECLC < 36.4 K (1/8 Watt)

At RECLC greater than 36.4 K, the current limit will be internally clamped to the nominal value.

IC(nom) is the nominal continuous current limit of the amplifier.

4.2.3External Current Limit - Peak (ECLP)

The peak current limit of the Dragonfly and Butterfly amplifiers can be scaled down by an external voltage or by an external resistor connected between pin J1/14 (ECLP) and J1/8 (ECLRET).

4.2.4External Voltage

An external positive voltage (0 to 3.75 V) to terminal J1/14 (ECLP) in reference to terminal J1/8 (ECLRET) will control the peak current limit from zero to Ip(nom).

Ip(new) =

VECLP

* Ip(nom)

3.75V

 

 

The voltage is internally clamped to 3.75 V whenever the external VECLP is higher than 3.75 V.

The external voltage source must be able to source/sink at least ±0.2 mA.

The maximum absolute VECLP allowed to be connected is 5 V.
