single-chip solutions to simplify the design and time to market

DALLAS March 7, 2012 / PRNewswire / - Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced two configurable analog front ends (AFE) that provide an easy to use, modular solution to fill the gap between the microprocessor and the sensor. Designers can significantly reduce development time using a single through the AFE nondispersive platforms gas multi-sensor infrared sensor (NDIR) and pH rather than designing more complex discrete solutions. The team ERA with IT WEBENCH ® design software sensor and AFE system development office. These tools allow engineers to choose a sensor, the design and configuration of the solution and download configuration data to the sensor AFE for immediate prototyping.

solution gas detection

complete

• : AFE integrates a programmable gain amplifier (PGA), "dark phase" shift circuit of the cancellation , set the common mode generator, and the SPI interface to simplify system design.
• programmable gain amplifier Features
• gain range of low gain and high-end, allowing the use of thermopiles with sensitivities different.
• well specified results:
low drift gain of 100 ppm / ° C output drift (maximum) shift of 1.2 mV / ° C , the change in phase delay of 500 ns, low noise 0.1 uV rms (0.1 to 10 Hz), and operation of -40 ° C to 105 ° C provide system performance optimized.

Small Form Factor

Integration package is reduced to 3 mm x 4.9 mm, allowing smaller end products.

The highly integrated AFE pH sensor LMP91200 supports two electrodes used in pH sensors analyzers platforms for monitoring emissions, water vapor and quality monitoring of water, chemical / petrochemical plants, food processing and more.

pH detection AFE

sensor pH of solution

: AFE integrates a PGA, ultra-low pH buffer input bias, the protection signal, and the temperature calibration of the measurement, and generating common mode and a diagnostic circuit, allowing the use of a single interface chip for most pH sensors day.

Increased reliability and accuracy of the system

test

onboard sensor ensures a good connection and functionality, and ultra-low bias current 0, 4 Pa ??(max) increases system reliability and accuracy while protecting the pH electrode in any situation of supply.
