The LTC®2410 is a 2.7V to 5.5V micropower 24-bit differential ∆ analog to digital converter with an inte-grated 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 LTC2410 can be configured for better than 110dB input differential mode rejection at 50Hz or 60Hz ±2%, or it can be driven by an external oscillator for a user defined rejection frequency. The internal oscillator re-quires 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 full-scale 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 indepen- dently set anywhere within the GND to VCC range of the LTC2410. The DC common mode input rejection is better than 140dB.
The LTC2410 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRETM protocols.
