ADS9120IRGER

具有增强型 SPI 接口的 16 位、2.5MSPS、单通道 SAR ADC 24-VQFN -40 to 125

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 scaling.

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 FPGAs.

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.
