Product Overview

The LTC2498CUHF#PBF is a 16-channel 24-bit delta-sigma™ Analog-to-digital Converter (ADC) with EasyDrive™ technology. 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 rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. It includes a high accuracy temperature sensor and an integrated oscillator. The integrated temperature sensor offers 1/30th °C resolution and 2°C absolute accuracy. It allows a wide common mode input range, independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel is selected is valid. Access to the multiplexer output enables optional external amplifiers to be shared between all analog inputs and auto calibration continuously removes their associated offse
  • EasyDrive™ Technology enables rail-to-rail inputs with zero differential input current
  • Directly digitizes high impedance sensors with full accuracy
  • Integrated high accuracy temperature sensor
  • GND to VCC Input/reference common mode range
  • No latency - digital filter settles in a single cycle, even after a new channel is selected
  • Internal oscillator
