Programmable gain or attenuation for signal-conditioning chains
The Texas Instruments LMP7312MA/NOPB is a programmable amplifier and attenuator — essentially a digitally-controlled analog front-end (AFE) that sets gain or attenuation under logic-level control. It accepts logic-level inputs and delivers logic-compatible outputs, making it a direct fit between a sensor or ADC and a microcontroller or FPGA without extra level-shifting.
2 mA supply — what it means for loop-powered and battery-backed designs
At 2 mA quiescent supply current, this part is suited for loop-powered transmitters where headroom matters.
That includes engine bay sensor conditioning, transmission control modules, and outdoor base-station power amplifiers. The 14-SOIC narrow-body package (3.90 mm width) fits standard PCB layouts without requiring a custom footprint.
