The LTC2485CDD#PBF is a 24-bit +sign delta-sigma™ Analog-to-digital Converter (ADC) with patented EasyDrive™ 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 and input signals, with rail-to rail input range to be directly digitized while maintaining exceptional DC accuracy. It includes an on-chip oscillator. The ADC can be configured through an I²C interface to reject line frequencies. It allows a wide common mode input range independent of the reference voltage. The reference can be as low as 100mV or can be tied directly to VCC. The ADC includes an on-chip trimmed oscillator eliminating the need for external crystals or oscillators. Absolute accuracy and low drift are automatically maintained through continuous, transparent, offset and full-scale calibration.
● EasyDrive™ Technology enables rail-to-rail inputs with zero differential input current
● Directly digitizes high impedance sensors with full accuracy
● GND to VCC Input/reference common mode range
● No latency - digital filter settles in a single cycle
● 2-wire I²C interface
● Selectable 2x speed mode
● Internal oscillator
● Six addresses available and one global address for synchronization
