CS5525  
CS5526  
16-Bit/20-Bit Multi-Range ADC with 4-Bit Latch  
Features  
General Description  
The 16-bit CS5525 and the 20-bit CS5526 are highly in-  
tegrated ∆Σ A/D converters which include an  
instrumentation amplifier, a PGA (programmable gain  
amplifier), eight digital filters, and self and system cali-  
bration circuitry.  
Delta-Sigma A/D Converter  
- Linearity Error: 0.0015%FS  
- Noise Free Resolution: 18-bits  
Bipolar/Unipolar Input Ranges  
- 25 mV, 55 mV, 100 mV, 1 V, 2.5 V and 5 V  
Chopper Stabilized Instrumentation Amplifier  
On-Chip Charge Pump Drive Circuitry  
4-Bit Output Latch  
Simple three-wire serial interface  
- SPI™ and Microwire™ Compatible  
- Schmitt Trigger on Serial Clock (SCLK)  
Programmable Output Word Rates  
- 3.76 Hz to 202Hz (XIN = 32.768 kHz)  
- 11.47 Hz to 616 Hz (XIN = 100 kHz)  
Output Settles in One Conversion Cycle  
Simultaneous 50/60 Hz Noise Rejection  
System and Self-Calibration with  
Read/Write Registers  
Single +5 V Analog Supply  
+3.0 V or +5 V Digital Supply  
The converters are designed to provide their own nega-  
tive supply which enables their on-chip instrumentation  
amplifiers to measure bipolar ground-referenced signals  
≤ 100 mV. By directly supplying NBV with -2.5 V and  
with VA+ at 5 V, ±2.5 V signals (with respect to ground)  
can be measured.  
The digital filters provide programmable output update  
rates between 3.76 Hz to 202 Hz (XIN = 32.768 kHz).  
Output word rates can be increased by approximately 3X  
by using XIN = 100 kHz. Each filter is designed to settle  
to full accuracy for its output update rate in one conver-  
sion cycle. The filters with word rates of 15 Hz or less  
(XIN = 32.768 kHz) reject both 50 and 60 Hz (±3 Hz) line  
interference simultaneously.  
Low power, single conversion settling time, programma-  
ble output rates, and the ability to handle negative input  
signals make these single supply products ideal solu-  
tions for isolated and non-isolated applications.  
Low Power Mode Consumption: 4.9 mW  
- 1.8 mW in 1 V, 2.5 V, and 5 V Input Ranges
