LTC2483 Datasheet | Linear Technology

LTC2483 16-Bit ∆Σ ADC with Easy Drive Input Current Cancellation and I2C Interface Features Easy Drive Technology Enables Rail-to-Rail Inputs with Zero Differential Input Current - Directly Digitizes High Impedance Sensors with Full Accuracy - 600n V RMS Noise, Independent of V REF - GND to V .. CC Input/Reference mon Mode Range - 2-Wire I2C Interface - Simultaneous 50Hz/60Hz Rejection - 2ppm (0.25LSB) INL, No Missing Codes - 1ppm Offset and 15ppm Full-Scale Error - No Latency: Digital Filter Settles in a Single Cycle - Single Supply 2.7V to 5.5V Operation - Internal Oscillator - Six Addresses Available and One Global Address for Synchronization - Available in a Tiny (3mm × 3mm) 10-Lead DFN Package - DESCRIPTIO The LTC®2483 bines a 16-bit plus sign No Latency ∆ΣTM analog-to-digital converter with patented Easy Drive TM technology and I2C digital interface. The patented sampling scheme eliminates dynamic input current errors and the shortings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and input signals, with rail-torail input range to be directly digitized while maintaining exceptional DC accuracy. The LTC2483 allows a wide mon mode input range (0V to VCC) independent of the reference voltage. The reference can be as low as 100m V or can be tied directly to VCC. The noise level is 600n V RMS independent of VREF. This allows direct digitization of low level signals with 16bit accuracy. The LTC2483 includes an on-chip trimmed oscillator, eliminating the need for external crystals or oscillators and provides 87d B rejection of 50Hz and 60Hz line frequency noise. Absolute accuracy and low drift are automatically maintained through continuous, transparent, offset and full-scale calibration. , LTC and LT are registered trademarks of Linear Technology Corporation.
