The TI ADS112U04 ADC stocked by the company is a four-channel 16-bit delta-sigma ADC that integrates a low-noise programmable gain amplifier (PGA) in a small, 16-pin 5.0 mm × 4.4 mm package. The ADS112U04 supports two differential inputs or four. Single-ended input measurement flexible input multiplexer providing four analog inputs. The integrated low-noise PGA supports gain settings from 1 to 128. For industrial applications in noisy environments, when the sampling rate is 20 SPS, digital The filter can suppress 50-Hz and 60-Hz noise at the same time.
The ADS112U04 integrates a highly linear internal temperature sensor with a typical accuracy of 0.5 °C, and a dual-match programmable current source (IDAC) for sensor excitation. This device minimizes digital data transmission through a 2-wire UART-compatible interface. Digitally isolated channels reduce cost and power consumption and save board space. The ADS112U04 supports an extended operating temperature range of –40°C to +125°C. In addition, the ADS1256EVM, a companion evaluation module, can be purchased from MOUSER.
