LINEAR TECHNOLOGY  LTC2488IDE#PBF  模数转换器, 四路 Δ-Σ, 16 bit, 7.5 SPS, 单, 2.7 V, 5.5 V, DFN

The is a 4-channel 16-bit delta-sigma™ Analog-to-digital Converter ADC with EasyDrive™ technology. The patented sampling scheme eliminates dynamic input current errors and the short comings 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 an integrated oscillator. This device can be configured to measure an external signal from combinations of 4 analog input channels operating in single-ended or differential modes. It automatically rejects line frequencies of 50Hz and 60Hz simultaneously. 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 selection is valid.
