DEVICE DESCRIPTION
The X96010 contains two independent Programmable
Current Generators in one package. The combination
of the X96010 functionality and Intersil’s QFN package
lowers system cost, increases reliability, and reduces
board space requirements.
Two on-chip Programmable Current Generators may
be independently programmed to either sink or source
current. The maximum current generated is deter-
mined by using an externally connected programming
resistor. Both current generators have a maximum
output of ±3.2 mA, and may be controlled to an abso-
lute resolution of 0.39% (256 steps / 8 bit).
Both current generators may be driven using an exter-
nal sensor or Control Registers. The external sensor
output drives a 8-bit A/D converter. The six MSBs of
the ADC output select one of 64 bytes from each 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 X96010,
including the look-up tables, are programmable via the
2-wire serial port.
