TI has analogue front ends for photometry

The new analogue ics, claimed to be the first in the industry, integrate all the front end components and associated timing control circuitry of a typical photometry solution. Applications include clinical and home health pulse oximeters, photometry based blood glucose meters and photoplethysmograph based heart rate monitors. By incorporating fully programmable transmitter and receiver circuits into one device, the AFE44xx family is said to reduce end equipment manufacturers' design time, board space and need for in house analogue design expertise compared to discrete solutions. With less than 1mA supply current, the AFE44xx family consumes less power than discrete solutions, which TI says results in longer battery life.
