Frequently Asked Questions
What resolution and conversion type does the ADS1242IPWRG4 offer?
The ADS1242IPWRG4 is a 24-bit delta-sigma ADC, providing extremely high resolution for precision measurement applications. The delta-sigma architecture oversamples the input signal and applies digital filtering, offering excellent noise rejection, inherent anti-aliasing, and very low total harmonic distortion.
How many analog input channels does the ADS1242IPWRG4 support?
The device features 4 analog input channels with an integrated multiplexer, allowing the single ADC core to be shared across multiple sensors. This reduces the external component count and PCB area required for multi-channel precision data acquisition systems.
What is the supply voltage range and linearity specification for the ADS1242IPWRG4?
The ADS1242IPWRG4 operates from an analog supply voltage of 2.7 V to 5.25 V and achieves a maximum linearity error of 0.0015%, ensuring highly accurate ADC transfer characteristics across its full-scale input range. This level of precision is suitable for calibrated industrial and scientific measurement systems.
What package does the ADS1242IPWRG4 come in, and what does the suffix mean?
The device is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package, R-PDSO-G16). The I suffix indicates industrial temperature range (-40°C to +85°C), PWR refers to the TSSOP package type, and G4 denotes RoHS-compliant (lead-free) construction.
What are typical applications for the ADS1242IPWRG4?
Typical applications include industrial weigh scales, strain gauge amplifiers, RTD and thermocouple temperature measurement, process control instrumentation, chromatography analyzers, and multi-channel data loggers. Any application needing high resolution, low noise, and multi-channel analog input in a compact package is well served by this device.
