Texas Instruments' ADS9110 is an 18-bit, 2 MSPS, successive approximation register (SAR) ADC with ±0.5 LSB INL and 100 dB SNR specifications under typical operating conditions. The high throughput enables developers to oversample the input signal to improve dynamic range and accuracy of the measurement.

The device supports unipolar, fully differential analog input signals and operates with a 2.5 V to 5 V external reference, offering a wide selection of input ranges without additional input scaling. The device consumes only 15 mW of power when operating at the full 2 MSPS throughput. Power consumption at lower throughputs can be reduced by using the flexible low-power modes (NAP and PD).

The integrated multiSPI serial interface is backward compatible to the traditional SPI™ protocol. Additionally, configurable features simplify board layout, timing, and firmware and achieve high throughput at lower clock speeds, thus allowing easy interface with a variety of microcontrollers, digital signal processors (DSPs), and field-programmable gate arrays (FPGAs).

The device supports JESD8-7A compliant I/Os, the standard industrial temperature range, and is offered in a space-saving, 4 mm x 4 mm, VQFN package.
