Datasheet Analog Devices AD1555APZ — Ficha de datos

a 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. FEATURES
