LTC2482CDD#PBF

LTC®2482 combines a 16bit plus sign No Latency ΔΣ™ analog-to-digital converter with patented Easy Drive technology. 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 and input signals with rail-to-rail input range to be directly digitized while maintaining exceptional DC accuracy. The LTC2482 allows a wide common mode input range (0V to VCC) independent of the reference voltage. The reference can be as low as 100mV or can be tied directly to VCC. Typical applications include direct sensor digitizer, weight scales, direct temperature measurement, strain-gauge transducers, instrumentation, industrial process control, DVMs and meters.

• Directly digitizes high impedance sensors with full accuracy
• 600nV rms noise, independent of Vref
• Operates with a reference as low as 100mv with 16bit resolution
• GND to VCC input/reference common mode range
• Simultaneous 50Hz/60Hz rejection mode
• 2ppm inl, no missing codes, 1ppm offset and 15ppm total unadjusted error
• No latency digital filter settles in a single cycle
• Single supply 2.7V to 5.5V operation and internal oscillator
• 10 lead DFN package
• Operating temperature range from 0°C to 70°C
