FEATURES  
DESCRIPTION

•
True Differential Inputs  
The ADC141S626 is a 14-bit, 50 kSPS to 250 kSPS  
sampling Analog-to-Digital (A/D) converter. The  
converter is based on a successive-approximation  
register (SAR) architecture where the differential  
nature of the analog inputs is maintained from the  
internal sample-and-hold circuits throughout the A/D  
converter to provide excellent common-mode signal  
rejection. The ADC141S626 features an external  
reference that can be varied from 1.0V to VA. It also  
features a zero-power track mode where the ADC is  
consuming the minimum amount of supply current  
while the internal sampling capacitor is tracking the  
applied analog input voltage.

External Reference  
Zero-Power Track Mode  
Wide Input Common-Mode Voltage Range  
Operating Temperature Range of −40°C to

SPI™/QSPI™/MICROWIRE/DSP Compatible  
Serial Interface  
APPLICATIONS  
The serial data output is binary 2's complement and  
is compatible with several standards, such as SPI™,  
QSPI™, MICROWIRE, and many common DSP  
serial interfaces. The conversion result is clocked out  
by the serial clock input and is the result of the  
conversion currently in progress; thus, ADC141S626  
has no latency.

Instrumentation and Control Systems  
Motor Control  
Direct Sensor Interface  
The ADC141S626 may be operated with independent  
analog (VA) and digital input/output (VIO) supplies. VA  
and VIO can range from 2.7V to 5.5V and can be set  
independent of each other. This allows a user to  
maximize performance and minimize power  
consumption by operating the analog portion of the  
ADC at a VA of 5V while communicating with a 3V  
controller on the digital side. With a 3V source, the  
power consumption when operating at 200 kSPS is  
2.0 mW. With a 5V source, the power consumption  
when operating at 250 kSPS is 4.8 mW. The power  
consumption drops down to 4 µW and 13 µW

low power consumption, and small size make the  
ADC141S626 ideal for direct connection to bridge  
sensors and transducers in battery operated systems  
or remote data acquisition applications.  
Operation is guaranteed over the temperature range  
of −40°C to +85°C and clock rates of 0.9 MHz to 4.5  
MHz. The ADC141S626 is available in a 10-lead  
VSSOP package.
