AD7190 24-Bit Sigma-Delta ADC

Analog Devices Inc. AD7190 24-Bit Sigma-Delta ADC is offered as a low-noise, complete analog front end designed for high-precision measurement applications. AD7190 includes a low-noise, 24-bit sigma-delta (∑-Δ) analog-to-digital converter (ADC). An on-chip, low-noise gain stage allows small amplitude signals to interface directly to the ADC. Designers can configure the device with two differential inputs or four pseudo-differential inputs. Analog Devices AD7190 ADC delivers an output data rate of 4.7Hz to 4.8kHz and provides two digital filter options. The AD7190 operates with a 5V analog power supply and a digital power supply from 2.7V to 5.25V. This device consumes a current of 6mA and is available in a 24-lead TSSOP package.
