3 Description  
The ADC141S628-Q1 device is a 14-bit, 200-kSPS,  
pseudo-differential, analog-to-digital converter (ADC)  
that is AEC-Q100 grade 2 qualified. The converter is  
based on a successive-approximation register (SAR)  
architecture and has pseudo-differential analog  
inputs. The signal path is maintained from the internal  
sample-and-hold circuits throughout the ADC to  
provide excellent common-mode noise rejection. The  
ADC141S628-Q1 features a zero-power track mode  
where the ADC is consuming the minimum amount of  
supply current while the internal sampling capacitor  
tracks the applied analog input voltage.  
Zero-Power Track Mode  
±150-mV Swing Around GND on Negative Input  
Separate Digital I/O and Analog Supplies  
Operating Temperature Range of –40°C to  
+105°C  
SPI™, QSPI™, Microwire, DSP-Compatible Serial  
Interface  
Conversion Rate: 50 kSPS to 200 kSPS  
INL (–15°C to +65°C): ±0.95 LSB (max)  
DNL: ±0.95 LSB (max)  
The serial data output of the ADC141S628-Q1 is  
straight binary and is compatible with several  
standards, such as SPI, QSPI, Microwire, and many  
common DSP serial interfaces. The ADC141S628-Q1  
has no latency which means the conversion result is  
clocked out by the serial clock input and is the result  
of the conversion currently in progress.  
Post Calibration TUE (–15°C to +65°C): ±0.5 mV  
(max)  
SNR: 80 dBc (min)  
THD: –97 dBc (typ)  
ENOB: 13.0 Bits (min)  
Power Consumption:  
The ADC141S628-Q1 can be operated with  
independent analog (VA) and digital input/output  
(VIO) supplies. VA and VIO can range from 4.5 V to  
5.5 V and can be set independent of each other. This  
functionality allows a user to maximize performance  
and minimize power consumption. Similarly, the  
ADC141S628-Q1 uses an external reference that can  
be varied from 1.0 V to VA allowing users to optimize  
the full dynamic range of the input. The pseudo-  
differential input, low power consumption, and small  
size make the ADC141S628-Q1 ideal for remote data  
acquisition applications.  
200 kSPS, 5 V: 4.8 mW (typ)
