Low-Noise 24-bit Delta Sigma ADC
ISL26132, ISL26134
The ISL26132 and ISL26134 are 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 and ADS1234 devices and are
functionally compatible with these devices. The ISL26132 and
ISL26134 offer improved noise performance at 10Sps and
80Sps conversion rates.
The on-chip low-noise programmable-gain amplifier provides
gains of 1x/2x/64x/128x. The 128x gain setting provides an
input range of ±9.766mVFS when using a 2.5V reference. 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 (4.9152MHz typical), or the on-chip oscillator.
The two channel ISL26132 is available in a 24 Ld TSSOP
package and the four channel ISL26134 is available in a 28 Ld
TSSOP package. Both are specified for operation over the
automotive temperature range (-40°C to +105°C).
