The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.
The ADS8472 combined with the THS4032 offers similar functionality.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The ADS8254 is a high-performance analog system-on-chip (SoC) device with an 16-bit, 1-MSPS A/D converter, 4-V internal reference, an on-chip ADC driver (OPA), and a 4-channel differential multiplexer. The channel count of the multiplexer and auto/manual scan modes of the device are user selectable.
The ADC driver is designed to leverage the very high noise performance of the differential ADC at optimum power usage levels.
The ADS8254 outputs a buffered reference signal for level shifting of a ±4-V bipolar signal with an external resistance divider. A Vref/2 output signal is available to set the common-mode of a signal conditioning circuit. The device also includes an 16-/8-bit parallel interface.
The ADS8254 is available in a 9 mm × 9 mm, 64-pin QFN package and is characterized from 40°C to 85°C.
