The LTC 2439-1 is a 16-channel (8-differential) micropower 16-bit analog-to-digital converter. It operates from 2.7V to 5.5V and includes an integrated oscillator, 0.12LSB INL and 1V RMS noise. It uses deltasigma technology and provides single cycle settling time for multiplexed applications. Through a single pin, the LTC2439-1 can be configured for better than 87dB differential mode rejection at 50Hz and 60Hz 2%, or it can be driven by an external oscillator for a user-defined rejection frequency. The internal oscillator requires no external frequency setting components.
