The ADS9120 is a 16-bit, 2.5-MSPS, successive approximation register
(SAR) analog-to-digital converter (ADC) with enhanced performance features. The high throughput
enables developers to oversample the input signal to improve dynamic range and accuracy of the
measurement. The ADS9110 is a pin-compatible, 18-bit, 2-MSPS variant
of the ADS9120.
The ADS9120 boosts
analog performance while maintaining high-resolution data transfer by using TI’s enhanced SPI
feature. Enhanced SPI enables the ADS9120 to achieve high throughput at lower clock speeds, thereby
simplifying board layout and lowering system cost.
Enhanced SPI also simplifies the host clocking-in of data, thereby making the device
ideal for applications involving FPGAs and DSPs. The ADS9120 is compatible with a standard SPI Interface. The
ADS9120 has an internal data
parity feature that can be appended to the ADC data output. ADC data validation by the host, using
parity 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.
