Description
1
CPH
Upper Comparator Threshold Voltage Input, CPH > CPL.
2
CPL
Lower Comparator Threshold Voltage Input, CPL < CPH.
3, 18
DVDD
Digital Supply Voltage.
4
CPOH
Logic Output. When high, indicates MEASVOUT or MEASIOUT > CPH.
5
CPOL
Logic Output. When high, indicates MEASVOUT or MEASIOUT < CPL.
6
CPCK
Logic Input. Used to initiate comparator sampling and update CPOH and CPOL.
7, 17
DGND
Digital Ground.
8
CLHDETECT
Logic Output. When high, indicates upper clamp active. See the Clamp Function section.
9
CLLDETECT
Logic Output. When high, indicates lower clamp active. See the Clamp Function section.
10
QM4
Logic Output. When high, indicates current range Mode 4 is enabled. May be used to drive external relay or
switch. See the High Current Ranges section.
11
QM5
Logic Output. When high, indicates current range Mode 5 is enabled. May be used to drive external relay or
switch. See the High Current Ranges section.
12
MOE
Active Low MEASOUT Enable.
13
CS
Active Low Logic Input. The device is selected when this pin is low. See the Interface section.
14
STB
Active Low Logic Input. Used in conjunction with CPCK and CS to configure the device for different
configurations. Rising edge of STB triggers sequence inputs. See the Interface section.
15
AC0
Logic Input. Used in conjunction with AC1 to select one of three external compensation capacitors.
See the Force Control Amplifier section.
16
AC1
Logic Input. Used in conjunction with AC0 to select one of three external compensation capacitors.
See the Force Control Amplifier section.
19
AM2
Logic Input. Used in conjunction with AM1 and AM0 to select one of six current ranges or to enable standby
mode. See the Current Ranges section.
20
AM1
Logic Input. Used in conjunction with AM2 and AM0 to select one of six current ranges or to enable standby
mode. See the Current Ranges section.
21
AM0
Logic Input. Used in conjunction with AM2 and AM1 to select one of six current ranges or to enable standby
mode. See the Current Ranges section.
22
STANDBY
Logic Input. When high, device is in standby mode of operation. See the Standby Mode section.
