FUNCTION
SDA
1
I2C Serial Data. Input/output for I2C data.
SCL
2
I2C Serial Clock. Input for I2C clock.
FS1
3
FS0
5
Full-Scale Calibration Inputs. A resistor to ground on these pins determines the full-scale current
for each output. FS0 controls OUT0, FS1 controls OUT1.
GND
4
Ground
OUT0
6
OUT1
7
Current Outputs. Sinks or sources the current determined by the register settings and the
resistance connected to FS0 and FS1.

Typical Operating Characteristics
(Applies to OUT0 and OUT1. VCC = 2.7V to 5.0V, SDA = SCL = VCC, TA = +25°C, and no loads on OUT0, OUT1, FS0, or FS1, unless
otherwise noted.)
