ISL24201
The ISL24201 provides an 8-bit programmable current sink that
is used in conjunction with an external voltage divider and buffer
amplifier to generate a voltage source that is positioned between
the analog supply voltage and ground. The current sink’s
resolution is controlled by an external resistor, R
span of the V
resistor ratio and the source impedance of R
device has an 8-bit data register and 8-bit EEPROM for storing a
volatile and a permanent value for its output. The ISL24201 has
an I
and EEPROM. At power-up the EEPROM value is transferred to
the data register and output.
The ISL24201 is available in an 8 Ld 3mm x 3mm TDFN
package. This package has a maximum height of 0.8mm for very
low profile designs. The ambient operating temperature range is
-40°C to +85°C
