CS5531/32/33/34
16-Bit and 24-Bit ADCs with Ultra Low Noise PGIA
Features
Chopper Stabilized PGIA (Programmable
Gain Instrumentation Amplifier, 1x to 64x)
6 nV/鈭欻z @ 0.1 Hz (No 1/f noise) at 64x
500 pA Input Current with Gains >1
General Description
The CS5531/32/33/34 are highly integrated
鈭單?/div>
Analog-
to-Digital Converters (ADCs) which use charge-balance
techniques to achieve 16-bit (CS5531/33) and 24-bit
(CS5532/34) performance. The ADCs are optimized for
measuring low-level unipolar or bipolar signals in weigh
scale, process control, scientific, and medical
applications.
To accommodate these applications, the ADCs come as
either two-channel (CS5531/32) or four-channel
(CS5533/34) devices and include a very low noise chop-
per-stabilized instrumentation amplifier (6 nV/鈭欻z @ 0.1
Hz) with selectable gains of 1脳, 2脳, 4脳, 8脳, 16脳, 32脳, and
64脳. These ADCs also include a fourth order
鈭單?/div>
modu-
lator followed by a digital filter which provides twenty
selectable output word rates of 6.25, 7.5, 12.5, 15, 25, 30,
50, 60, 100, 120, 200, 240, 400, 480, 800, 960, 1600,
1920, 3200, and 3840 Sps (MCLK = 4.9152 MHz).
To ease communication between the ADCs and a micro-
controller, the converters include a simple three-wire se-
rial interface which is SPI and Microwire compatible with
a Schmitt Trigger input on the serial clock (SCLK).
High dynamic range, programmable output rates, and
flexible power supply options makes these ADCs ideal
solutions for weigh scale and process control
applications.
