AD1555 Product details

Description

24-Bit ⌺-⌬ ADC with Low Noise PGA AD1555/AD1556 high dynamic range measurement applications.The AD1555 outputs a ones-density bitstream proportional to the analog input.When used in conjunction with the AD1556 digital filter/ decimator, a high performance ADC is realized.The continuous-time analog modulator input architecture avoids the need for an external antialias filter.The programmable gain front end simplifies system design, extends the dynamic range, and reduces the system board area
