Supply LT Data Acquisition LTC2485CDD 24 Bit Analog to Digital Converter

LTC2485CDD combines a 24-bit plus sign No Latency ∆Σ™ analog-to-digital converter with patented Easy Drive technology and I2C digital interface. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances andinput signals, withrail-torail input range to be directly digitized while maintaining exceptional DC accuracy.
