5 Description (continued)

Another feature of the LMP9007x and LMP90080 is continuous background sensor diagnostics, allowing the

detection of open and short circuit conditions and out-of-range signals, without requiring user intervention,

resulting in enhanced system reliability.

Two sets of independent external reference voltage pins allow multiple ratiometric measurements. In addition,

two matched programmable current sources are available in the LMP90080/LMP90078 to excite external sensors

such as resistive temperature detectors and bridge sensors. Furthermore, seven GPIO pins are provided for

interfacing to external LEDs and switches to simplify control across an isolation barrier.

Collectively, these features make the LMP90080/LMP90079/LMP90078/LMP90077 complete analog front-ends

for low-power, precision sensor applications such as temperature, pressure, strain gauge, and industrial process

control. The LMP90080/LMP90079/LMP90078/LMP90077 are ensured over the extended temperature range of -

40°C to +125°C and are available in a 28-pin package with an exposed pad.
