Description
The CS5506 is a family of low power CMOS A/D converters which are ideal for measuring low-frequency signals representing physical, chemical, and biological processes. The on-chip digital filter offers superior line rejection at 50 and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Sps). The CS5506 include on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors. The CS5506 serial port offers two general-purpose modes for the direct interface to shift registers or synchronous serial ports of industry-standard microcontrollers.
- Very Low Power Consumption
- Single supply +5 V operation: 1.7 mW
- Dual supply ±5 V operation: 3.2 mW
- Offers superior performance to VFCs and multi-slope integrating ADCs
- Differential Inputs
- Four-channel (CS5506) pseudo-differential versions
- Either 5 V or 3.3 V Digital Interface
- Linearity Error:
- ±0.0007% FS (20-bit CS5506)
- Output update rates up to 100 Sps
- Flexible Serial Port
- Pin-Selectable Unipolar/Bipolar Ranges
