Texas Instruments  ADS9120IRGER

The ADS9120 is a 16-bit, 2.5-MSPS, successive approximation register(SAR) analog-to-digital converter (ADC) with enhanced performance features. The high throughputenables developers to oversample the input signal to improve dynamic range and accuracy of themeasurement. The ADS9110 is a pin-compatible, 18-bit, 2-MSPS variantof the ADS9120.

The ADS9120 boostsanalog performance while maintaining high-resolution data transfer by using TI’s enhanced SPIfeature. Enhanced SPI enables the ADS9120 to achieve high throughput at lower clock speeds, therebysimplifying board layout and lowering system cost.

Enhanced SPI also simplifies the host clocking-in of data, thereby making the deviceideal for applications involving FPGAs and DSPs. The ADS9120 is compatible with a standard SPI Interface. TheADS9120 has an internal dataparity feature that can be appended to the ADC data output. ADC data validation by the host, usingparity bits, improves system reliability.

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.
