The tolerance of the internal resistor can vary ±15% (typ) from its nominal value of 32 k

Ω;

thus the cut-off frequency will vary accordingly. A minimum capacitance of 2.5 nF for CLOAD

(x, y, z) is required.

An external capacitor can be added to the Vout pin. Values below 10 pF are recommended.

Soldering information

The LGA package is compliant with the ECOPACK®, RoHs and “Green” standard.

It is qualified for soldering heat resistance according to JEDEC J-STD-020C.

Leave “pin 1 Indicator” unconnected during soldering.

Land pattern and soldering recommendations are available at www.st.com.
