- ADS1235-Q1 — PGA 및 AC 여기를 갖춘 오토모티브 24비트, 7.2kSPS, 3채널 차동 입력, 델타-시그마 ADC
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.
The ADC supports ac-bridge excitation to remove the drift errors from the sensor wiring. The ADC provides the clock control signals for the ac-excitation operation.
The flexible digital filter is programmable for single-cycle settled conversions, and provides 50-Hz and 60-Hz line cycle rejection at the same time.
The ADS1235 is available in a 5-mm × 5-mm QFN package, and is specified across the –40°C to +125°C temperature range.
