The ADS9120 is an 16-bit, 2.5-MSPS, successive approximation register
(SAR) analog-to-digital converter (ADC) with ±0.25-LSB INL and 96-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
The device consumes only 15.5 mW of power when operating at the full 2.5-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
The device supports JESD8-7A compliant I/Os, the extended industrial temperature range, and is offered in a
space-saving, 4-mm × 4-mm, VQFN package.
