FEATURES  
DESCRIPTION  
2
•
AC Performance:  
The ADS1672 is  
a
high-speed, high-precision  
107dB of Dynamic Range at 625kSPS  
115.5dB of Dynamic Range at 78kSPS  
–115dB THD  
analog-to-digital converter (ADC). Using an advanced  
delta-sigma (ΔΣ) architecture, it operates at speeds  
up to 625kSPS with outstanding ac performance and  
dc accuracy.  
•
•
DC Accuracy:  
3ppm INL  
2µV/°C Offset Drift  
2ppm/°C Gain Drift  
The ADS1672 ADC is comprised of a low-drift,  
chopper-stabilized modulator with out-of-range  
detection and a dual-path programmable digital filter.  
The dual filter path allows the user to select between  
Programmable Digital Filter with  
User-Selectable Path:  
two  
post-processing  
filters:  
low-latency  
or  
wide-bandwidth. The low-latency filter settles quickly  
in one cycle, for applications with large instantaneous  
changes, such as a multiplexer. The wide-bandwidth  
path provides an optimized frequency response for ac  
measurements with a passband ripple of less than  
0.001dB, stop band attenuation of 115dB, and a  
bandwidth of 305kHz.  
–
–
Low-Latency: Completely settles in 5.5µs  
Wide-Bandwidth: 305kHz BW with flat  
passband  
•
Flexible Read-Only Serial Interface:  
–
–
Standard CMOS  
Serialized LVDS  
The ADS1672 is controlled through I/O pins—there  
are no registers to program. A dedicated START pin  
allows for direct control of conversions: toggle the  
START pin to begin a conversion, and then retrieve  
the output data. The flexible serial interface supports  
data readback with either standard CMOS and LVDS  
logic levels, allowing the ADS1672 to directly connect  
to a wide range of microcontrollers, digital signal  
processors (DSPs), or field-programmable grid arrays  
(FPGAs).  
•
•
•
•
Easy Conversion Control with START Pin  
Out-of-Range Detection  
Supply: Analog +5V, Digital +3V  
Power: 350mW  
APPLICATIONS  
•
•
•
•
Automated Test Equipment  
Vibration Analysis  
Sonar  
The ADS1672 operates from an analog supply of 5V  
and digital supply of 3V, and dissipates 350mW of  
power. When not in use, the PDWN pin can be used  
to power down all device circuitry. The device is fully  
specified over the industrial temperature range and is  
offered in a TQFP-64 package.
