Description
The ISL26132 is a complete analog front ends for high resolution measurement applications. These 24-bit Delta-Sigma Analog-to-Digital Converters include a very low-noise amplifier and are available as either two or four differential multiplexer inputs. The devices offer the same pinout as the ADS1232 device and is functionally compatible with these devices. The ISL26132 offer improved noise performance at 10Sps and 80Sps conversion rates. 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 (4.9152MHz typical), or the on-chip oscillator. The two channel ISL26132 is available in a 24 Ld TSSOP package and operate over the automotive temperature range (-40°C to +105°C).
