INTERSIL SENSOR CONDITIONER PRODUCT FAMILY
FSO = Full Scale Output, Ext = External, Int = Internal
DEVICE DESCRIPTION
The combination of the X96011 functionality and Inter-
sil’s QFN package lowers system cost, increases reli-
ability, and reduces board space requirements.
The on-chip Programmable Current Generator may be
independently programmed to either sink or source
current. The maximum current generated is deter-
mined by using an externally connected programming
resistor, or by selecting one of three predefined val-
ues. Both current generators have a maximum output
of ±1.6 mA, and may be controlled to an absolute res-
olution of 0.39% (256 steps / 8 bit).

The current generator is driven using either an on-
board temperature sensor or Control Registers. The
internal temperature sensor operates over a very
broad temperature range (-40
sor output drives an 8-bit A/D converter. The six MSBs
of the ADC output select one of 64 bytes from the non-
volatile look-up table (LUT).
The contents of the selected LUT row (8-bit wide)
drives the input of an 8-bit D/A converter, which gener-
ates the output current.
All control and setup parameters of the X96011,
including the look-up table, are programmable via the
2-wire serial port.
