General Description

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 V_A. 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.

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.

The ADC141S626 may be operated with independent analog (V_A) and digital input/output (V_IO) supplies. V_A and V_IO 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 V_A 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 respectively when the ADC141S626 enters acquisition (power-down) mode. The differential input, 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 MSOP package.
