Features
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.
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
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 CS5505/6/7/8 sample
upon command up to 100 Sps.
(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 Sps
l Flexible Serial Port
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 CS5505/6/7/8 include on-chip self-calibration cir-
cuitry which can be initiated at any time or temperature
to ensure minimum offset and full-scale errors.
l Pin-Selectable Unipolar/Bipolar Ranges
The CS5505/6/7/8 serial port offers two general-purpose
modes for the direct interface to shift registers or syn-
chronous
serial
ports
of
industry-standard
microcontrollers.
