ISL26132AVZ

The ISL26132AVZ is a low-noise delta sigma Analog-to-digital Converter (ADC) for high resolution measurement applications. These 24-bit delta-sigma analog-to-digital converter includes a very low-noise amplifier and are available as either two or four differential multiplexer inputs. The ADC offers improved noise performance at 10Sps and 80Sps conversion rates. The high input impedance allows direct connection of sensors, such as load cell bridges to ensure the specified measurement accuracy without additional circuitry. The inputs accept signals 100mV outside the supply rails when the device is set for unity gain. The delta-sigma ADC features a third order modulator providing up to 21.6-bit noise-free performance. The device can be operated from an external clock source, crystal or the on-chip oscillator.
