ADS1601  
www.ti.com  
SBAS322D –DECEMBER 2004–REVISED OCTOBER 2011  
16-Bit, 1.25MSPS Analog-to-Digital Converter  
Check for Samples: ADS1601  
1
FEATURES  
DESCRIPTION  
The ADS1601 is  
delta-sigma analog-to-digital  
a
high-speed, high-precision,  
converter (ADC)  
2
•
High Speed:  
–
–
Data Rate: 1.25MSPS  
Bandwidth: 615kHz  
manufactured on an advanced CMOS process. The  
ADS1601 oversampling topology reduces clock jitter  
sensitivity during the sampling of high-frequency,  
large amplitude signals by a factor of four over that  
achieved by Nyquist-rate ADCs. Consequently,  
signal-to-noise ratio (SNR) is particularly improved.  
Total harmonic distortion (THD) is –103dB, and the  
spurious-free dynamic range (SFDR) is 105dB  
•
Outstanding Performance:  
–
–
–
SNR: 92dB at fIN = 100kHz, –1dBFS  
THD: –103dB at fIN = 100kHz, –6dBFS  
SFDR: 105dB at fIN = 100kHz, –6dBFS  
•
Ease-of-Use:  
Optimized for power and performance, the ADS1601  
dissipates only 330mW while providing a full-scale  
differential input range of ±0.94VREF. Having such a  
wide input range makes out-of-range signals  
uncommon. The OTR pin indicates if an analog input  
out-of-range condition does occur. The differential  
input signal is measured against the differential  
reference, which can be generated internally on the  
ADS1601 or supplied externally.

High-Speed 3-Wire Serial Interface  
Directly Connects to TMS320 DSPs  
On-Chip Digital Filter Simplifies Anti-Alias  
Requirements  
–
Simple Pin-Driven Control—No On-Chip  
Registers to Program  
–
–
Selectable On-Chip Voltage Reference  
Simultaneous Sampling with Multiple  
ADS1601s  
The ADS1601 uses an inherently stable advanced  
modulator with an on-chip decimation filter. The filter  
stop band extends to 19.3MHz, which greatly  
simplifies the anti-aliasing circuitry. The modulator  
samples the input signal up to 20MSPS, depending  
on fCLK, while the 16x decimation filter uses a series  
of four half-band FIR filter stages to provide 75dB of  
stop band attenuation and 0.001dB of passband  
ripple.

APPLICATIONS  
•
•
•
Sonar  
Output data is provided over a simple 3-wire serial  
interface at rates up to 1.25MSPS, with a –3dB  
bandwidth of 615kHz. The output data or its  
complementary format directly connects to DSPs  
such as TI’s TMS320 family, FPGAs, or ASICs. A  
dedicated synchronization pin enables simultaneous  
sampling with multiple ADS1601s in multi-channel  
systems. Power dissipation is set by an external  
resistor that allows a reduction in dissipation when  
operating at slower speeds. All of the ADS1601  
features are controlled by dedicated I/O pins, which  
simplify operation by eliminating the need for on-chip  
registers.
