Texas Instruments  ADC141S628QIMMX/NOPB

The ADC141S628-Q1 device is a 14-bit, 200-kSPS, pseudo-differential, analog-to-digitalconverter (ADC) that is AEC-Q100 grade 2 qualified. The converter is based on asuccessive-approximation register (SAR) architecture and has pseudo-differential analog inputs. Thesignal path is maintained from the internal sample-and-hold circuits throughout the ADC to provideexcellent common-mode noise rejection. The ADC141S628-Q1 features a zero-power track mode where theADC is consuming the minimum amount of supply current while the internal sampling capacitor tracksthe applied analog input voltage.

The serial data output of the ADC141S628-Q1 is straight binary and is compatible withseveral standards, such as SPI, QSPI, Microwire, and many common DSP serial interfaces. TheADC141S628-Q1 has no latency which means the conversion result is clocked out by the serial clockinput and is the result of the conversion currently in progress.

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 tooptimize 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.

Operation is specified over the temperature range of –40°C to +105°C and clock rates of0.36 MHz to 3.6 MHz. The ADC141S628-Q1 is available in a 10-lead package.
