LDMOS RF Power-Amplifier Bias
Controller
SDA and SCL Pullup Resistors
SDA is an open-collector output on the DS1870 that
requires a pullup resistor to realize high logic levels. A
master using either an open-collector output with a
pullup resistor or a push-pull output driver can be used
Advanced Application
A circuit showing the implementaion of current sensing
using the DS1870 is shown under Advanced
Application with Current Sense.
for SCL. Pullup resistor values should be chosen to
ensure that the rise and fall times listed in the AC elec-
trical characteristics are within specification.

NOTES:
1) IN THIS CONFIGURATION, THE VOLTAGE RANGE OF W 1 AND W 2 IS
3V-5V. THIS RANGE CAN BE EXTENDED USING EXTERNAL RESISTORS.
2) ONE MAX6156B CAN BE USED WITH MULTIPLE DS1870s.
