The LMP90100 and LMP91000 configurable sensor analog front end (AFE) ICs from National Semiconductor Corp., Santa Clara, CA, together with the company's WEBENCH Sensor AFE Designer software, let you select a sensor, design and configure the system, and download configuration data to the sensor AFE. The LMP90100 multichannel, low-power, 24-bit sensor AFE has true continuous background calibration and diagnostics. Its 24-bit sigma-delta ADC has a flexible input configuration to interface with any combination of differential or single-ended inputs. The LMP91000 is a configurable low-power potentiostat that is suited for use in micropower chemical and gas sensing applications. The AFE measures current in a potentiostat that is proportional to the gas concentration, generating an output voltage proportional to the cell current using a transimpedance amplifier.
