CS5507

CS5505/6/7/8 Very Low Power, 16-Bit and 20-Bit A/D Converters Features l Very Low Power Consumption - Single supply +5 V operation: 1.7 mW - Dual supply ±5 V operation: 3.2 mW l Offers superior performance to VFCs and multi-slope integrating ADCs l Differential Inputs - Single Channel (CS5507/8) and Four-Channel (CS5505/6) pseudo-differential versions l Either 5 V or 3.3 V Digital Interface l Linearity Error: - ±0.0015% FS (16-bit CS5505/7) - ±0.0007% FS (20-bit CS5506/8) l Output update rates up to 100/second l Flexible Serial Port l Pin-Selectable Unipolar/Bipolar Ranges Description The CS5505/6/7/8 are a family of low power CMOS A/D converters which are ideal for measuring low-frequency signals representing physical, chemical, and biological processes. The CS5507/8 have single-channel differential analog and reference inputs while the CS5505/6 have four pseudo-differential analog input channels. The CS5505/7 have a 16-bit output word. The CS5506/8 have a 20-bit output word.The...
