Conditions

VSET (Pin 7)

PIN = 0 dBm; measurement mode2

PIN = −65 dBm; measurement mode2

PIN = −10 dBm; VSET = 2.1 V

TEMP (Pin 13)

TA = 25°C, RLOAD = 10 kΩ

−40°C ≤ TA ≤ +85°C, RLOAD = 10 kΩ

TA = 25°C

ENBL (Pin 16)

ENBL = 5 V

ENBL = 0 V; sourcing

VPSI (Pin 3 and Pin 4), VPSO (Pin 9)

ENBL = 5 V

−40°C ≤ TA ≤ +85°C

ENBL = 0 V, total currents for VPSI and VPSO

−40°C ≤ TA ≤ +85°C

1 Controller mode.

2 Gain = 1. For other gains, see the Measurement Mode section.
