Description
General part information
ADS1235 Series
The ADS1235 is a precision, 7200-SPS, delta-sigma (ΔΣ) analog-to-digital converter (ADC) with an integrated programmable gain amplifier (PGA). This device also includes diagnostic features such as PGA overrange and reference monitors. The ADC provides high-accuracy, zero-drift conversion data for high-precision equipment, including weigh scales, strain gauges, and resistive pressure sensors.
The ADC has signal and reference multiplexers that support three differential signal inputs and two reference inputs. The ADC also includes a low-noise PGA that provides gains of 1, 64, and 128. The ADC also has a 24-bit ΔΣ modulator and programmable digital filter.
The high-impedance inputs (1 GΩ) of the PGA reduce measurement error that is caused by sensor loading.
