3 Description
The 10-bit AFE532A3W and the 8-bit AFE432A3W
(AFEx32A3W) are a three-channel, buffered voltageoutput,
current-output, and ADC-input smart analog
front end (AFE). The AFEx32A3W devices support
a current source that can be used for linear
control of laser diodes and miniature motors. These
devices support Hi-Z power-down mode and Hi-
Z output during power-off conditions for voltage
output. Channel 1 can be configured as an ADC,
voltage-output DAC or a comparator. The voltageoutput
DACs provide a force-sense option for use
as a programmable comparator and current sink.
The multifunction GPIO, function generation, and
programmable nonvolatile memory (NVM) enable
these smart AFEs for processor-less applications and
design reuse. These devices automatically detect SPI
or I2C interfaces and contain an internal reference.
The AFEx32A3W feature set combined with the tiny
package and low power make these smart AFEs an
excellent choice for applications such as laser diode
power control and electro-absorption modulated laser
(EML) control in passive optical network (PON) and
other industrial laser applications.
