LTC2413 24-Bit No Latency Delta Sigma™ with Simultaneous 50Hz/60Hz Rejection ADC

The LTC®2413 is a 2.7V to 5.5V simultaneous 50Hz/60Hz rejection micropower 24-bit differential Delta Sigma analog to digital converter with an integrated oscillator, 2ppm INL and 0.16ppm RMS noise. It uses delta-sigma technology and provides single cycle settling time for multiplexed applications. Through a single pin, the LTC2413 can be configured for better than 87dB input differential mode rejection over the range of 49Hz to 61.2Hz (50Hz and 60Hz ±2% simultaneously), or it can be driven by an external oscillator for a user defined rejection frequency. The internal oscillator requires no external frequency setting components.

The converter accepts any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The fullscale differential input range is from �0.5VREF to 0.5VREF. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be independently set anywhere within the GND to VCC range of the LTC2413. The DC common mode input rejection is better than 140dB.

The LTC2413 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE™ protocols
