16-bit sigma-delta ADC with integrated PGA in a 16-TSSOP tube
The ADS1146IPW is a 16-bit sigma-delta ADC from Texas Instruments, configured as MUX-PGA-ADC with a single differential or single-ended input channel. It samples at 2k SPS and communicates over an SPI data interface, requiring an external voltage reference. Housed in a 16-TSSOP package supplied in tubes, this part is suited for precision measurement applications where the on-chip PGA conditions low-level sensor signals before conversion.
Supply range and temperature grade
Both analog and digital supply rails accept 2.7V to 5.25V, simplifying single-supply designs when the same rail powers the ADC core and the SPI bus. The -40°C to 105°C operating temperature range covers industrial and extended-commercial environments — suitable for factory-floor sensor interfaces and process-control modules that see ambient heat from adjacent power stages.
