LTC2412
2-Channel Differential Input
24-Bit No Latency ∆Σ ADC
FEATURES DESCRIPTION 2-Channel Differential Input with Automatic Channel Selection (Ping-Pong)
nn Low Supply Current: 200µA, 4µA in Autosleep
nn Differential Input and Differential Reference with
GND to VCC Common Mode Range
nn 2ppm INL, No Missing Codes
nn 2.5ppm Full-Scale Error and 0.1ppm Offset
nn 0.16ppm Noise, 22.5 Effective Number of Bits
nn No Latency: Digital Filter Settles in a Single Cycle and
Each Channel Conversion is Accurate
nn Internal Oscillator—No External Components Required
nn 110dB Min, 50Hz or 60Hz Notch Filter
nn Narrow SSOP-16 Package
nn Single Supply 2.7V to 5.5V Operation The LTC®2412 is a 2-channel differential input micropower
24-bit No Latency ∆Σ™ analog-to-digital converter with an
integrated oscillator. It provides 2ppm INL and 0.16ppm
RMS noise over the entire supply range. The two differential channels are converted alternately with channel ID
included in the conversion results. It uses delta-sigma
technology and provides single conversion settling of the
digital filter. Through a single pin, the LTC2412 can be
configured for better than 110dB input differential mode …
