LTC2402CMS#PBF Datasheet PDF - Linear Technology

●The LTC2402CMS#PBF is a 2-channel 24-bit micropower No Latency delta-sigma A/D Converter with an integrated oscillator, 4ppm INL and 0.6ppm RMS noise. This ultra small device uses delta-sigma technology and a new digital filter architecture that settles in a single cycle. This eliminates the latency found in conventional Delta Sigma converters and simplifies multiplexed applications. Through a single pin, the LTC2402 can be configured for better than 110dB rejection at 50/60Hz ±2% or can be driven by an external oscillator for an user defined rejection frequency in the range 1 to 120Hz. The internal oscillator requires no external frequency setting components. This converter accepts an external reference voltage from 0.1V to VCC. With an extended input conversion range of -12.5 to 112.5% VREF (VREF = FSSET - ZSSET), the LTC2402 smoothly resolve the offset and over range problems of preceding sensors or signal conditioning circuits.
